Uploading large files

By default, SharePoint supports uploading files up to 50 MB in size. Here’s how to change the maximum file size:

1. Go to “Central Administration" in SharePoint and then to “Configure Virtual Server Settings from Virtual Server List Page.”

2. Select your server.

3. Go to “Virtual Server General Settings” (in the “Virtual Server Management” block).

4. Change the value of the maximum upload size in MB.

If you increase the file size limit, your site might occasionally time out for users while they are uploading files. To accommodate this issue you have to increase the default time out property for IIS.

If you receive error message when you try to upload a large file to a document library, use information from Microsoft 365 troubleshooting to resolve the problem.
