Description red_Arti 2024-02-19 06:29:18 UTC 
SUMMARY
I store some temporary work middle files in some tmpfs like `/dev/shm` or `/tmp`.
I use Dolphin to explore those paths.
Deleting files under those paths will move them into `/home/xxx/.local/share/Trash` .
I see folders (permission 700) `/tmp/.Trash-1000` and `/dev/shm/.Trash-1000` but Dolphin not using them.

`/home` is harddisk. `/tmp` or `/dev/shm` are in memory. Deleting files from memory should definitly NOT move them into harddisk

STEPS TO REPRODUCE
1. 
2. 
3. 

OBSERVED RESULT
Deleting files from `/tmp` or `/dev/shm`, Dolphin moves them into  `/home/xxx/.local/share/Trash`

EXPECTED RESULT
Dolphin should move deleted files into `/tmp/.Trash-1000` or `/dev/shm/.Trash-1000`

...

no option for user to set trash path or modify the list.
Comment 1 red_Arti 2025-07-30 13:27:13 UTC 
Please consider this: Add an option. Let user decide the behavior of trashing a file. Enable/Disable cross-disk trashing. 

Windows never move cross partition/disk/filesystem, when trashing files. I think that's the right way.

trash: don't fallback to home trash if trash is unavailable

If no trash can be created for the partition or network share, it might
not be desirable to move a file to the main trash on the home partition.
Especially when the partition is tmpfs (like /tmp), it would be
counterintuitive when the files would be persisted when it is "removed".
Even though this means, we can no longer test trash by using files
under /tmp.

So instead provide the user with a choice to delete the file
directly.
