We strive to make it as easy as possible for you to quickly and easily get your data into Logikcull! This article will cover how to do a file upload. This means that you have native data files, typically stored somewhere locally on your device, that you would like to upload into Logikcull. A file upload may suit your purposes if:

  • You have exported a .PST file from Outlook

  • You have exported an MBOX file from Google Workspace

  • Your client has provided you with a folder of PDFs to review

  • You exported a zip file containing JSON files from Slack

  • Any other scenario involving native data without an accompanying load file

There are three ways to upload data into Logikcull:

File Upload

Drag and drop a file or browse for the file on your computer. Detailed instructions can be found below.

Cloud Upload

Pull files directly from Slack, Microsoft 365, Google Vault, or Learn more about Cloud uploads here. πŸ”—

Database Upload

Upload productions or databases from other systems into Logikcull using a load file. Full step by step instructions for database upload can be found here. πŸ”—

File Upload Instructions

To start your file upload, select Now, just drag-and-drop individual files, folders, or containers (i.e., ZIP, PST) onto the upload page and fill in the blanks in the pop-up form:

  1. Name your upload. Drag and Drop or select browse to locate the individual files, folder, ZIP, or PST you are uploading.

  2. Assign a custodian* (required) by choosing an existing custodian or adding a new one. After adding a custodian, hit Enter to save your selection.

    *Please note that the assigned custodian cannot be changed or modified after the upload, so take care when assigning a custodian at this stage. Read more about custodian assignment here.

  3. Select the drop-down arrow next to "More options" to add a note about the upload.

Select "Start Upload" to start the upload. If you dragged/dropped the wrong file(s), just click "x" next to the file and choose a different file to upload.


What happens after I kick off my upload?

Your upload of native electronic documents will now be transferred, processed, and prepared for your team's review. A progress bar will appear to show you what stage your upload is currently in, and we'll notify you when the process is completed:

  1. Transferring: The data is being transported from your local machine to Logikcull’s secure cloud environment. It is important during this stage to keep the browser window active. The upload cannot begin processing until the entire data set is completely transferred.

  2. Scheduled: Your upload has been received and may now be queued in line behind one or more other uploads within this project. At this point, you can safely navigate away from the Uploads page at any time knowing that we've received your data and will process it in the order in which it was received.

  3. Analyzing Data: Your uploaded data is now being scanned and shuttled through the heart of Logikcull, where documents are virus-scanned, applying OCR or text extraction, searching for DTR, passing through language detection, rendering to PDF and web-viewable formats, and much more, before moving on to Post-Processing.

  4. Post-Processing: Logikcull is now wrapping up its work on your uploaded data by applying applicable Auto Tags (QC Tags), analyzing duplicates, indexing all text into our search engine, and syncing up with previous uploads. Once Post-Processing is complete, your upload will be ready and you'll receive a highly detailed notification via email.

Note: Uploads can only be cancelled during the Transferring stage. If you would like to delete an upload, see this article here for more information.

Will I need to ZIP my files prior to uploading into Logikcull?

For most file uploads, nope! Logikcull will collect and zip up your files automatically. However, depending on file size limitations for your device or browser, you may be prompted to zip your files first. We recommend using Keka for Mac, or 7-Zip for Windows/Linux. See here for additional guidance on recommended ZIP software.

Why is my Project's storage size larger than what was uploaded?

Data expands as part of Logikcull’s comprehensive processing workflow, an automated process that is essential to maintaining the integrity of your information. When you upload documents, Logikcull preserves, organizes and enhances them to:

  1. Ensure files are secure: this entails scanning for hard-to-detect viruses, preserving metadata to protect against spoliation, and encrypting files at rest.

  2. Speed up the search and review process: this includes:

    1. Deduplication πŸ”—

    2. Running Deep Text Recognition and Optical Character Recognition πŸ”— on document images

    3. Indexing metadata πŸ”— so you can find documents easily

    4. Flagging potentially privileged documents (see Auto Tags below)

    5. Rendering PDF image snapshots πŸ”— of native documents for easy review

    6. Applying Auto Tags πŸ”— to provide insights into document metadata and processing

These processes occur automatically, so no need to worry whether key data is being missed or processes are being skipped. This automation allows Logikcull to repeat the same processes consistently and reliably across all data sets.

Migrating data into Logikcull

Migrating an active matter from an alternative review platform into Logikcull can bring significant cost savings and improved functionality, while allowing you to maintain work product and continuity of review. This downloadable guide shows you how, from initial considerations to the technical details. We’ve broken the process into three parts:

  1. Exporting your data

  2. Importing your data to Logikcull

  3. Post-upload quality control

How do I import and view emails from Outlook (PST file) or Gmail (MBOX file)?

We support the following formats for email:


Typically we see Outlook email being exported as a PST file, and Gmail email as MBOX. You can choose to use a third-party solution for your export, or depending on what version you have, you can use the built-in tools to get these files. See What kind of files can I upload into Logikcull? for more information.

Once you have these email files, just drag and drop into Logikcull!*

* Please note: If you are uploading Outlook PST files, the PST should be disconnected from MS Outlook before uploading. To disconnect the PST, Open Outlook > Right-click the Personal Folders file (i.e. the PST) that you want to remove from the Navigation Pane > Click Close Personal Folders.

How do I connect an external hard drive to upload custodian data?

Connect, drag, and drop - but beware of older hardware!

⚠️ Beware of older hardware!

USB transfer rates are not all equal, and can dramatically impact time to transfer:

  • USB 1.0: 1.5 Megabits per second (Mbps)

  • USB 1.1: 12 Megabits per second (Mbps)

  • USB 2.0: 480 Megabits per second (Mbps)

  • USB 3.0: 5 Gigabits per second (Gbps)

  • USB 3.1: 10 Gigabits per second (Gbps)

USB 3.0 and 3.1 ports are more common in modern computers. You should note, however, that it does not always live up to its potential. USB transfer rates are limited by the slowest connected device. Even when two USB 3.1-compatible devices are connected, there is a chance the speeds will fall short of what the device is capable of.

Troubleshooting Failed Uploads

A failed upload can be caused by one or a variety of different factors. Here are some troubleshooting steps you can investigate:

Optimize for data transfer.

For file uploads, the first phase - Transferring (i.e., yellow progress bar) - relies on your Internet connection to get documents over to Logikcull for processing. We recommend the following to help move your upload through the transfer stage and into processing:

  • Upload from a local drive (i.e., desktop files) as opposed to a shared drive or a thumb drive.

  • Plug into a high-speed DSL line (as opposed to WiFi). You can check Internet speed here:

  • Stay logged into Logikcull while the item is transferring. You can adjust computer sleep settings to ensure the system does not go to sleep during the transfer process.

  • If you're trying to upload a spanned zip (e.g. items ending in .zip.001 or .z001) please first extract all parts of the spanned zip, starting with the first section, and re-combine the entire volume in a non-spanned format to upload to Logikcull.

Check for password protection on the file.

If your file is password-protected, Logikcull will load it as a 0 byte file. We recommend decrypting the password protection prior to uploading into Logikcull.

PST still connected to Outlook.

We typically see best results when uploading PSTs if the item is uploaded from a local drive such as a desktop (vs. a shared drive), and also if the PST is disconnected from Outlook.

To disconnect the PST, Open Outlook > Right-click the Personal Folders file (i.e., the PST) that you want to remove from the Navigation Pane > Click Close Personal Folders.

Corrupt PST

Fortunately, this can be easily remedied using ScanPST, a program that is meant to specifically address corrupt PST files.

⚠️ Keep in mind, ScanPST can alter/delete data when used with a damaged PST. More information about this can be found here:
