I have over a thousand merged (duplicate) files and they take a lot of space. For some reason they don’t appear in the duplicate checker. The only way I know of deleting them is to go in the scenes file info tab, one by one, and delete the duplicate. I read somewhere that there was a plugin to facilitate just that but I could not find such a plugin.
This must be a very common problem so I’d be amazed if there was no solution to this.
So I had a very similar issue as well, I no longer do but it did take me a long time to clean up. Unfortunately as far as I know there is no “easy” way to do it. I had to use a combination of things to clean up my collection.
Run it through the dup checker plugin. I ran it so it would check for any length and then selected 1 by 1 exact, high, medium, low.
Then I used a the filter to show “file count greater than 1” and started to manually go into each one and delete the dup scene. That part is the tedious part. So what I did since I also use the renamer plugin and it sorts each performer/scene into folders for me I would just go into each folder and look for the files that have a “_1 or _2” at the end of them and just delete those files.
Then just run the clean up process in Stash. Most of the time if a scene gets merged they should have the same file name so it should end with that.
From what I can tell the plugin for the dup checker is looking for unmerged scenes, but I could be wrong on that. I guess since you have a lot of dups you can try to unmerge a few and see if the dup checker catches them. But even then that would be a lot of manual work since I dont think there is a plugin to unmerge scenes.
Someone with a bit more knowledge might know a better way but that is the way I had to do it since I was getting multiple packs of content of certain performers and you never know what may be in them.
Thanks for this, I was wondering the same and this seems to be the easiest (though not easy) way to do it. Seems almost like an oversight that you can’t delete Merged files automatically.
