Description

Currently, copying a 5G file to a vfat drive will first spend a lot of time copying, then give a message "error splicing file", fortunately also mentioning that the file size was too large.

It'd be nice if Thunar could notice that it's copying into a vfat file system and mention before trying that it won't be possible to copy such a large file.
