FILE CANNOT BE SAVED BECAUSE THE FILE SIZE EXCEEDS THE PERMITTED LIMIT

[realperest]

Hello.
I want to share a flash disk, open it from UTM and copy a file from there to UTM WIN side.

About 10 gb. outlook.pst file

When I copy paste, I get an error message that the FILE CANNOT BE SAVED BECAUSE THE FILE SIZE EXCEEDS THE PERMITTED LIMIT.

Is there a solution for this?

How are you copying the file? Via the folder sharing feature, or via USB? If the file is on a USB flash drive, you could try using the USB sharing feature instead of folder share, as that doesn't have a file size limitation. (the limit here is probably the Windows WebDAV client IIRC)

I'm seeing this issue to - using the folder sharing feature.

I see the issue too. I have mapped a macOS folder using Spice webdav. I can successfully browse it. I am doing drag & drop from the network drive Z: (SPICE webdav mapped) to desktop and getting this error.

File size: the limit seems to be 50MB (42MB was fine, 52MB throws the error)
host: macOS 13.5
guest: Windows 11 ARM
UTM 4.3.5 (87)

Solved: I increased webdav size limit in windows registry (FileSizeLimitInBytes) and it works now.

Ok, so any idea how we solve this for a 5GB file? You can only increase the WebDAV limit so much :(

For future reference

Tip

To solve this The file size exceeds the limit allowed and cannot be saved

1. Open regedit by
   • Press command + R
   • Type regedit
2. in the address bard go copy the following and press enter

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

4. Open the FileSizeLimitinBytes
5. Add max value ffffffff
