Run the following commands in bash to generate a directory with 3000 empty files: 1.1 mkdir /tmp/dolphin_copy_test_src /tmp/dolphin_copy_test_dst 1.2 cd /tmp/dolphin_copy_test_src 1.3 for ((i=1;i<=3000;i++)); do touch $(uuidgen); done 2. Open Dolphin file manager, preferably from terminal 3. Navigate to /tmp/dolphin_copy_test_src 4. Press Ctrl+A to select all 3000 files in directory 5.
