SUMMARY While trying copying files to a USB stick(FAT formatted), I observed that if a directory's name was changed by an automatic action, Dolphin will fail to copy content of that directory. STEPS TO REPRODUCE 1. Make a directory with a name that contains characters that target file system doesn't like ( '|' for example) 2. Add some files to that directory 3. Try to copy/move the directory to a FAT filesystem(USB stick) via Dolphin 4. It will ask you to rename offending characters, choose "rename" option. OBSERVED RESULT 5. Dolphin will now fail to copy files that were in the directory. EXPECTED RESULT - Files copied/moved normally.
