Bug 324384

Dolphin should warn about some operations that aren't supported by the FS. For example, copying a 8GB file to a FAT32 drive will always fail (because FAT32 can't handle such a big file), so instead of trying to copy it, Dolphin should halt the action, explaining why it can't be done.

Another example: Some FS don't support some characters in the file name (NTFS doesn't support ¿?/ and a few others, EXT* doesn't support /). Dolphin should warn about such unsupported characters instead of writing them (as writing them may cause volume soft-failure, another OS not being able to read the volume, or any other bugs).



Reproducible: Always

Steps to Reproduce:
1. Copy a +4GB file.
2. Paste to a FAT32 volume
3. Error
Actual Results:  
Dolphin fails after copying ~4gb of the file

Expected Results:  
Dolphin should halt the operation instead of trying to do it (as it will fail always)
