Warning: Error opening file (mp4, Windows)

[bugmenot]

Hi all,
I'm trying to rename an mp4 file using exiftool under windows. However, I'm not able to open it.

Code Select Expand

> exiftool.exe -v3 -api largefilesupport=1 .\PXL_20240811_095552201.mp4
ExifToolVersion = 12.92
FileName = PXL_20240811_095552201.mp4
Directory = .
Error = Error opening file
It works using Ubuntu, but not Windows. Am I missing something?

Thanks in advance!

The only way I can see this happing is if you don't have read permission for the file.

Other possibility might be a path length that exceeds MAXPATH. Approx. 260 chars.

Permissions and file size are correct, but I found the solution. As said, the issue was with Windows. The files are on a Nextcloud and mounted on my PC using WebDAV. Apparently, by default Windows limits the file size for WebDAV to 50MB. By increasing this, I could open the files :-)

For anyone stumbling across this issue, search for Windows Error 0x800700DF to find out how to fix this.
