I am so obsessed with programming that I am surprised when everyday products just work and do not fall apart when being used.

When file managers copy and delete files within the same partition instead of moving or renaming them…

When Google's Storage Access Framework was introduced, it did not feature a move command, so file managers just resorted to copying and deleting files within the same storage. Not only does this cause needless wear and is much slower, but it also destroys the date/time attribute (it gets changed to current).

When moving files through MTP (miserable transfer protocol, used for connecting smartphones to PC), they are also copy-deleted. This makes moving a 20-Gigabyte DCIM folder impractical. Also, if one cancels the operation, it might end up whoopsie-daisy deleting some files from the source before they have been transferred.

MTP is so bogus that it is incapable of a simple operation that would JustWork™ on mass storage devices. Not to mention, MTP lacks parallelism and its directory listing loading it S-L-O-W. Upwards of a minute for just 1000 files. Sometimes, it fails loading at all.

Also, trying to rename a file through MTP using the terminal through GVFS, even if just within the same folder, it copy-deletes it. If I want to rename a 1 GB 2160p 4K video in a highly populated DCIM folder, I can not do so through the terminal. At least, the 4K video has a time stamp in its internal metadata, but it still renames slowly and adds needless wear to the smartphone's flash memory.
