Maximum file size you can Upload or Download

Authors list

The maximum individual file size that you can upload through our progress bar uploader is 20GB. That's quite a large file - roughly the contents of 4 DVDs or the equivalent of combining 200,000 documents into one file.

In places where you can upload several files at a time, the limit applies to individual files, not the total of all files.

Note: If you're using our "Accessible Uploader," the upload limit is 512MB.

When uploading very large files, remember the upload will only go as fast as the slowest point on the network between your computer and the Kahootz servers. That's often your own internet connection, particularly if shared with other users at your location.

Kahootz Tip: You can add more than one document at once! If you add a file with the same name as an existing document, instead of creating a new document, your new file will be added as a new version of the existing file.

Zip files

When uploading a ZIP file, you can either keep it as a single file or expand it in the workspace.

If your ZIP file contains folders and you choose to expand it, the folder structure inside your ZIP file will be recreated in your workspace. New versions of documents will be created if they already exist in your workspace.

Note: The maximum amount of files a ZIP can contain is 200.

Comments, Tasks, and Related Items

It's possible to enable comments, tasks, and related items now, or at a later date:

  • Comments allow you to receive feedback from users, so you don't have to chase them to hear what they think!
  • Adding tasks helps keep track of who's actually read or edited the document. You can assign a task to a workspace member, which they'll need to mark as done once they've read/edited it.
  • Another useful tool is connecting items which have related content - this works well as a "See also" tool.


When downloading, the file size is not limited to how many documents you have, but the ZIP file it will generate in the background.

When you click "Download all Documents" it requests the server to generate this file in the background and for several reasons, we have to limit that job.

If your ZIP file is smaller then it will run, otherwise, you'll be presented with an error message advising you have exceeded the size limit.
