I have created network drive connected to webdav server. When I try to upload file(4gb) then I see file size as -1 on the webdav server request. What is the max file size limit and how to change the time out? as the webdav client is sending delete req when uploading large files.

The default file size limit for WebDAV in Windows is set to 50MB. This restriction is implemented to avoid performance issues during file transfers. Users frequently encounter this limit, causing frustration when uploading critical files.

You can check it right here :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileSizeLimitInBytes
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileAttributesLimitInBytes

Once you’ve located the registry key, the next step is to modify the ‘FileSizeLimitInBytes’ entry. Changing this value will increase the file size limit for WebDAV transfers. Double-click on the ‘FileSizeLimitInBytes’ entry and increase its value to a higher number. The maximum value you can set is FFFFFFFF, which corresponds to a 4GB limit.

Restart your computer after this change to apply the new settings. This reboot is necessary for the system to recognize and apply the updated registry values effectively.

Hi Joseph... I have done the registry changes and restarted the webclient service. And the file size limit changes are applied. Can we do anything to make it support more than 4GB file? Because I am using this webdav as mounted drive to hit my local webdav server to upload files to cloud. And it is not supporting more than 4GB.

Hi K,

Currently, the limit remains at 4GB. It's possible that Microsoft may implement an update to change this in the future, but as of now, I have not received any official information regarding such a change. For the time being, you will need to split the file into segments under 4GB and send them individually.

You can try to use a tool like 7-Zip to split:

7z a -v4000m bigfile_split.7z bigfile.iso

Upload the split archives and reassemble them on the destination.
