For exaple: when ripping an audio CD to MP3, and the tracks are named by an online database, it is possible that k3b will generate mp3 files with characters like ":" "><" "?" "\". If you want to copy these files to an USB drive or a SD card for your car, you run into problems because your car expects a FAT32 media source. Trying to copy a file with : or ? in its name to a FAT32 device in Dolphin leads to an ugly error. The attempt will be refused. Suggestion: Make copying to FAT32 more user friendly. -check if the destination file system has "forbidden" characters. If so, show a dialog with the options to abort copying or the option to make the destination filename compatible on the fly. -offer an option in the action menu: Rename File Windows Compatible SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
