SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** When I try to overwrite a larger file with a smaller one on fat32 micro SDcard, Dolphin deletes contents of file. After reinserting the sdcard, it becomes noticeable. STEPS TO REPRODUCE 1. Have hard drive formatted as btrfs, exfat, ext4, or anything, and sdcard formatted as fat32. 2. Make text file "config.txt" on hard drive and edit with Kate so it has "less text\n" 3. Make text file "config.txt" on fat32 sdcard and edit with Kate so it has "whatever text\n" 4. Drag and drop from hard drive to sdcard, select copy here, and overwrite. 5. It appears it has worked, but reinsert sdcard and open "config.txt" file on sdcard with Kate and it is empty "". I have two hard drives with btrfs and exfat and they both did same thing. Also I am using Vivitar sdcard reader MOV416-WHT. OBSERVED RESULT Open "config.txt" file on sdcard with Kate and it is empty "" EXPECTED RESULT Open "config.txt" file on sdcard with Kate and it should have "less text\n" SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian (available in About System) KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 Kernal version: 5.10.0-21-rt-amd64 ADDITIONAL INFORMATION Albert Astals Cid tried to replicate the bug, but couldn't.
