MTP is deprecated technology from 2004, supports no parallelism and has enormous latency issues, yet there has not yet been any successor. In my experience, MTP sometimes glitches by not displaying existing files. And sometimes, already moved and deleted files are still listed (filename visible, but obviously not openable). If one moves or deletes a folder, the entire contents including files not displayed due to a MTP glitch will be gone. MTP's *moving*, even when just moving **within the phone**, first copies and then deletes instead of moving immediately, which is usually possible within a file system. If you wish to move directories from your phone to the computer (i.e. for space freeing), I recommend: 1. Copy 2. Compare file sizes (bytes) and counts on computer and on the phone (using a file managing app on the phone itself) 3. Delete on phone if file size matched. If you wish to move directly, only do it on file level (select files, no folders), to avoid the risk of MTP glitch data loss. Or alternatively, just use USB-OTG or SMB (if it works).
