Uploading Native Data on Everlaw

To read more about uploading documents on Everlaw, please refer to the articles in our Uploads section. 

Table of Contents

Everlaw has a cloud-processing system that will automatically process native files for ingestion into the platform. This includes de-NISTing, deduping, and generating text, metadata, and images for your documents.

A native upload can contain one file, or multiple files. You can also retroactively upload new documents to an existing upload (This is useful if you want to group related documents together. See the “Preparing your native data for upload” section for more information). Uploaded documents go through three stages of processing before being added to your case: examine, PDF, and text.

Accepted native data types

Native data are copies of the original data in the format generated by the originating application. For example, Microsoft word creates .doc and .docx files. Everlaw supports automatic native uploading and processing for the following file formats:

Email and Chat Formats Web Formats Microsoft Office Formats Image Formats Container Files

EML, Gchat, iChat, Slack, Lotus Notes (NSF), MBox, MSG, OST, PST

HTML, MHTML, SVG All modern formats, such as docx, pptx, xlsx, etc. All original formats, such as doc, ppt, xls, etc.  Apple graphics, BMP, CAL, DCX, DIB, EMF, GIF, JPG, MIL, PDC, PCT, PCX, PNG, PSD, RAS, TGA, TIFF (all compression types), WMF, and many more .7Zip, AD1, E01, Gzip, L01, PST, Rar, Tar, TrueCrypt, Zip, .Zip.001
Medical Image Files CAD Formats Audio and Video Other Formats  
DCM DGN (V7, V8), DWG, DXF Most common audio and video formats Google Drive files (Docs, Sheets, Slides, etc) ICS, PList, PostScript, TXT, Source Code, SQLite databases, WPD

Unsupported files might return an ‘error’ during the 'examine' stage of the upload process. If so, these files can be accessed via the upload card by clicking on the ‘examine' stage. You can review the files to see what the filetype is, and reach out to Everlaw support (support@everlaw.com) for troubleshooting help. If you upload an unsupported file, one of two things can happen: If you are trying to upload file types not included in the box above, such as SQL databases, please reach out to support@everlaw.com.  

  • Unsupported files could also be categorized as ‘binary‘ files. In this case, these documents will not return any errors during processing, but will not display properly during review. Please see the “Troubleshooting upload errors” section for more information about how to find and troubleshoot these documents. Once identified, you can reach out to Everlaw support (support@everlaw.com) for help.

Preparing your native data for upload


In order to make the native upload process as smooth as possible, please keep the following in mind:

  • For documents without embedded text, Everlaw will automatically generate text for .pdf and .tiff images using optical character recognition (OCR). Text embedded in .pdf or .tiff images is automatically extracted, and the image is updated to allow for hit highlighting and text selection within the image view of the document. If you need to have text generated for files in a different image format, please contact Everlaw support.
  • Be aware that CGM and Shockwave files do not work well with our platform. If you want to add these files to your case, please reach out to support@everlaw.com for help.
  • If you have documents with multiple custodians, make sure documents of the same custodian are organized in their own sub-folders. You can create one top-level folder with any number and depth of sub-folders, but make sure that all documents within each sub-folder are from the same custodian. This is useful for preserving document path information, and will save you from having to specify the proper custodian at the document-level during the native upload process.
    • If you are uploading via a cloud-based app, like Drive and Dropbpox, you can only define one custodian per file, including zip files. This means all files within a zip file should belong to one custodian. For an in-depth guide on uploading files with multiple custodians, please see this article


  • If you are uploading a large folder, or a top-level folder that contains many subfolders, use a program like 7zip or iZip to compress the top-level folder before uploading. The uploads page will not accept folders.
  • If any of your files or folders are password-protected, make sure that you know the password(s) as you will need to provide them during the upload process. Inaccessible files and folders will not be processed or uploaded into the platform.
  • If your upload includes multiple documents, make sure that you are comfortable propagating the same time zone to documents that do not have a time zone specified in the metadata. If you want to propagate different time zones to documents in an upload that do not have a time zone specified, you should break up your upload in multiple uploads.

All documents in an upload will be added to an uploads card on the homepage. Some review teams like using these cards to organize uploaded documents. For example, you might want to add all documents from a particular custodian to a single upload card. In that case, you would want to ensure that all documents in a particular upload are from the same custodian, and that subsequent data from the custodian are added to the original upload as opposed to a new upload.

Please keep your preferences in mind as you prepare and package your documents for upload, and as you decide whether to create a new upload or add documents to an existing upload.

Preparing split archives for upload

 If you are uploading a forensic image archive that is split up into several parts (e.g. parts example.E01, example.E02, and example.E03), there are special preparations to undertake to make sure that our system can handle them correctly.

First, files in a split archive must be uploaded together in a single container (zip, tar, etc). Second, inside this archive you should have all the parts for the archive, and nothing else aside from summary/information files generated by the software that produced the E01/L01 file. No other types of files, like PDF's or emails, should be included. 

All the files in the container should be in a single directory. Here are examples of good and bad container files and their contents: 

   - folder1/folder2/part.E01
   - folder1/folder2/part.E02
   - folder1/folder2/part.E01_summary.txt
Bad (not all in same directory):
   - folder1/part.E01
   - folder1/part.E02
   - folder2/part.E03
Bad (not all in same directory):
   - part.E01
   - part.E02
   - folder1/summary.txt
Bad (lots of extra files):
 - part.E01
 - part.E02
 - misc.pst
 - file.pst
 - random.xyz (or whatever suffix is included)
Please contact Everlaw Support if you have any additional questions about uploading split archives.

Creating a native data upload
To access the uploads page:
  • Click the admin icon in the top right-hand corner of the navigation bar
  • Select “Uploads” from the dropdown menu
  • Select “New Upload” on the left-hand sidebar


Here, you can add the data you want to upload. Please see the “Preparing your native data for upload” section for information on how to prepare your files.

Uploading via cloud-based apps: 

At the bottom of the screen, you will see options to upload via popular cloud based storage apps. At this time, you can upload directly from the following apps: 

  • Box
  • Dropbox
  • Google Drive
  • SharePoint
  • One Drive

You can also select "direct link" to copy-paste a direct download URL. Make sure you have copied a shareable link. 

  • Shareable link: For a Google Drive document, you can obtain a shareable link by clicking on the blue Share button in the top right corner of the document, then clicking "Get shareable link" in the top right of the share dialog. 
  • Non-shareable link: An example of a non-shareable link is the URL located in the address bar of a document in Google Drive. This is a personal URL for your Drive account; if other users attempt to use the URL to view the document. Make sure you are always pasting in a shareable link, and not a non-shareable link, when uploading using the cloud uploader.

Once you click an app, you will be asked to log in via a separate dialog box. After logging in, you will be able to select a zip file directly from that app's site. Once you hit "enter" or "submit" within that app, you will be taken to the next step in the upload process. 


Once you select your file, you will be asked to specify whether you’re uploading native files or processed files. Choose "native."


Once you’ve made your selection, a wizard will appear where you can specify settings for the upload:

Step 1: Dataset details


  • Dataset Name: The name you give here will appear as the name of the associated uploads card on the homepage. The card will also display the date of the upload.
  • Display Timezone: The timezone you select here will be used as the assumed timezone for metadata fields that lack an explicit timezone value. If you do not select a timezone, then the timezone provided as raw text from the PDF's or emails being uploaded will be displayed. 
  • Create PDFs: By default, Everlaw creates PDF images for all files in an upload, and placeholder images for file types that don’t image well (like spreadsheets). If desired, you can choose to image the file types that don’t image well, or choose to not image any of the files in an upload.
  • Deduplication: Upon upload, you can choose to:
    • Deduplicate against all of the existing documents in your database
    • Deduplicate against all of the existing documents by custodian
    • Not deduplicate the documents in an upload
  • Duplicates of documents other than emails are identified using the hash value. Email duplicates are identified through the content, headers and attachments. All attributes must be exactly the same for an email to be deemed a duplicate.
  • Passwords: If any of your files/folders are password-protected, input the password(s) into the password box (one password per line). Inaccessible files will not be processed.

Step 2: Select custodians


The custodians step allows you to specify what custodian value to associate with the documents you’re uploading. You can specify a default custodian for all documents in an upload and/or set custom custodian values for particular files or folders.  

To set a default custodian, input the custodian name into the “default custodian” box at the top of the table.

To set custom custodian values for particular files or folders, find the file/folder on the table and input the custodian name into the custodian box on the right. If there is a default custodian, it’ll be overridden for that particular file/folder. Files that have a black caret symbol in the far left can be expanded to display the individual sub-folders/files they contain. Click on the caret icon to expand or collapse. 

Step 3: Uploading into children and partial projects

Aside from uploading the documents into the current database you’re on, you can also add the uploaded documents to any partial project you have access to. In addition, documents you upload will automatically be added to all complete projects associated with the primary database (ie. projects that share all of the documents from the primary database). The upload will be added to any project that has been selected in the table. To select or deselect a project, click on the checkbox. You cannot deselect complete projects.


Once you click ‘upload’, your data will be transferred to our servers. An overlay will appear to show you the status of the transfer. From the overlay, you can add additional documents to the upload by clicking on the “+Add files” button. If you don’t want to add files, close out of the overlay and you’ll be able to see your full native upload history.


A status card will be added to the native data page corresponding to your upload. A time estimate will appear on this status card to indicate approximately how long it will be until processing is complete. As your upload progresses, you can start reviewing completed docs. You do not need to stay on this page for the upload to continue processing. Once all your files are successfully processed, you will see a document icon with a green checkmark in the status card. Clicking the icon will take you to a results table of your processed documents.  


Note that uploaded native files will not be assigned EVER numbers; instead they will have a “#” value as its prefix. Documents already on the platform will keep their assigned EVER numbers.


To learn how to view upload status, rerun, delete, rename, and take other actions, please see the “Managing native uploads” section.

Managing native uploads

Your native upload history will appear in the “Native Data” section on the upload and productions page.


You can take the following actions on an upload status card:


1. Rename the upload

2. Click the three-dot menu icon to:

  • Manage source files
  • View configuration
  • Delete the upload

3. Click on the document count to see your uploaded documents

4. View a report of your uploads

Here are some additional details about these actions:

  • Manage source files: When you select this option, a dialogue box will appear. You can see if previous files have been successfully transferred to Everlaw’s servers for processing.  You can also add more files by clicking “add files” in the bottom right. Adding files to an existing upload is a good way to keep related files, such as files from the same custodian, together in a single upload.
  • View configuration: View the timezone propagated to your documents and projects the data was uploaded to.
  • Delete an upload: The documents in the upload, including the files generate during processing, will be removed from your database.
  • View report: The native uploads reporting tool will analyze your upload, including the upload errors and billable size. 

The pie chart in the middle of the report shows a breakdown of the file types that have been processed and uploaded. You can also see the absolute number documents for each file type using the list on the left. At the top, you can see the number and size of documents that were deduplicated or de-NISTed.  At the bottom, you can view the number of documents that were OCR’d and imaged, as well as the billable size of the upload. Finally, the right panel shows the number of documents that registered errors during processing, broken down by processing stage. Any number in blue is clickable, and will bring you to a results table with the appropriate documents.  Print the report by clicking “print report” in the bottom right-hand corner.


If you are on the homepage, you can access documents from a completed native upload from the Document Sets column. The card’s name will be “Natives:” followed up the name of the upload (the name of the title given upon upload).  Native upload cards have a dark orange band.

Updating an existing native upload

You can retroactively re-configure native documents that have already been uploaded. For example, you can change the timezone information, create image files that weren’t initially imaged, or re-run documents that weren’t initially processed because of a missing or incorrect password.

To update documents, first run a search to fetch the ones you want to alter. You can use the uploaded search term to quickly pull up documents from a particular upload. Then, use additional terms to get a subset of those documents, if desired.


Next, click the blue Begin Review button to pull up the results table. Finally, click export, choose to the Process tab from the resulting menu, select any re-configurations you need, and hit Process.

Troubleshooting native upload errors

Native files go through three stages during processing: examine, PDF conversion, and text conversion. Your data may experience issues during any of these stages.  For example, upon examine stage, the system may be unable to open the content of a container file (such as a zip file), which could contain thousands of important documents. It is important to examine these errors, and reach out to support@everlaw.com if you experience these issues. 

To view issues, click any of the stages, displayed as red icons in each status card (if they exist). Clicking on the number of issues within a stage will open a results table with the affected documents.


You can also locate documents based on potential issues through the reporting tool.

Please refer to the “accepted native data types” section to learn more about what could happen if you uploaded an unsupported filetype. You can also look at the uploads and productions FAQ page for answers to questions we commonly see.

Sometimes errors can be fixed if you re-run the upload. You can re-run documents from the results table view. See the "Updating an existing upload" section for more details.

Reach out to support@everlaw.com if you need help troubleshooting upload errors or to re-run uploads.
