Permission denied when copying some files ( due to certain characters in the file name)

Hello Everyone.

I have a Vero 4K+ with an external USB connected to it, mounting it via fstab and shared via samba.

When I want to add files to the vero, I transfer them via samba share on the vero.

The problem is some files I try share fail to copy. This seems to be down to certain characters in it. For example, Japanese or Chinese characters, ?, Some quotation marks (e.g. this fails but this " copies fine)

If I connect the hard drive to my computer and copy them directly and connect it backup to the Vero, I can watch the videos just fine which makes me think it’s something samba related

my fstab to mount the drive

UUID="5DFC-C6EC" /media/EXT vfat user,uid=osmc,gid=osmc,umask=022,relatime 0 0

Is the drive formatted as FAT32?
We don’t recommend this for larger files.

Thanks sam. It is FAT32. But it is not a file size issue, these are typically between 10 and 100MB.

It’s to do with the certain characters in the file name, as renaming the file to remove these characters lets the file copy fine.

I believe FAT16/FAT32 only supports short filenames and UTF-16 filenames are stored in a hacky way that won’t work well on Linux.

Unfortuante, as the same drive and copying method was working fine with a WDTV. Thanks for the assistance

Have you tried changing this to UTF16?

Special characters can be an issue in SMB shares.
