Feature: Support filtering in/out unavailable images

[przemoc]

Is your feature request related to a problem? Please describe.

1. Avoid seeing unavailable images.
2. Display only unavailable images, so that they could be easily selected and removed.

Describe the solution you'd like Additional filter, Availability, which could be enabled, and then filtered by true of false.

Describe alternatives you've considered For 1.: not aware of any. For 2.: there could be a button to remove unavailable images.

Additional context Recently there was change in behavior that previously indexed images that are no longer available are kept in DB. It is reasonable approach in the context of removable storage, but there are also users not using removable media that may reorganize their images outside of DiffusionToolkit, so it would be good to be able to still remove stale content without extra effort (which seems to be necessary now, unless I'm missing some obvious feature).

BTW Thanks for creating DiffusionToolkit!

The thing is that Unavailable images aren't a database "data point", if that makes sense. They only happen if the user deletes the image without Diffusion Toolkit knowing, so I have to do at least a directory scan everywhere to find them. This is pretty fast, but it requires scanning through the entire hard disk (or at least all the subdirectories under each watched folder). I assume it's really fast anyway, and that Windows is just checking the file table if it's there, but I still would rather avoid making unnecesary file scans, so I don't necessarily want a filter for Available images.

I've added an menu item to scan and delete / tag for delete unavailable images.

This build artifact should have these changes, if you don't want to wait for an official build:

Thank you for letting me know. I downloaded g9269cd0 build that you linked, which allowed me to remove some stale entries.

I noticed one issue, though. I was in Search view, which was showing many Unavailable entries, before I used Tools > Unavailable Files. I chosen Delete immediately option, upon starting progress bar quickly reached ~70%, it seemed to be stuck, but eventually I got information that images were deleted. When I returned to main window, Unavailable entries were still showing and number of results in status bar has not updated. I had to change view to something else and go back to Search view to make it stop showing Unavailable entries and update number of results in status bar.

hi, what if auto tag is used with first scan of available images and then only available tag is used, just like favorites and tags or albums? would this solve this issue? tag: show available and unavailable? or this is exactly what the new updates in this beta build meant?
