Windows Error 0x800700df

[BrentS]

Describe the issue
When I attempt to copy a large file from the network share folder or the virtual CD/DVD drive, I receive an "Error 0x800700df: The file size exceeds the limit allowed and cannot be saved." I have attempt two known Windows solutions - increasing the "FileSizeLimitInBytes" registry entry for WebClient and ensuring WebClient is running.

Configuration

• UTM Version: 2.4.1 (40)
• OS Version: Windows 11 ARM 22523.1000, OS Monterey 12.1
• Intel or Apple Silicon? Apple Silicon

I'm not sure if something can be done on the UTM side about the WebDAV file size limit. I can only recommend: for large files or professional use, don't use the WebDAV file sharing. Instead, configure your VM to use Bridged Network and make a SMB share in the VM or host.

Much appreciated! I disabled the SPICE kit sharing feature, connected via the network, and everything works. Thanks!

I was able to copy the file after editing the registry value. afaik, the hard limit for webdav protocol is 4G. it can rarely be reached.

Worked for me, too. For anyone else wondering, go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters.
Change FileSizeLimitInBytes to 0xFFFFFFFF hex or 4294967295 decimal and click OK.

I got the same issue for coping a 2.9GB file, what is the solution?

Change FileSizeLimitInBytes to 0xFFFFFFFF hex or 4294967295 decimal and click OK

That worked. Seems to need a restart though.

This also worked for me, however, for some reason, the copied and pasted hex value was never accepted by regedit, and I had to use the pasted decimal value instead. I also did a restart afterward.

This is not working for me. I tried both decimal and hex, and rebooted the windows 11 box.

Still not allowing large file sharing..

anyone have any thoughts ?

Something else I later figured out, is that the Windows Bitlocker was creating issues, and turning it off helped me. At that time I was trying to install legit software and could not, but turning off Bitlocker helped. I cannot promise it will help with your situation, but worth a try maybe.

Still not working, instead I've used the following way:

• copy needed files to external USB device or external SSD
• just use USB devices to share whole drive
• copy needed files
• unmount
