Two folders:
X:\Folder1
Y:\Folder2

both folder1 and folder2 with sub folders.

Talking about many files (60,000 or so).

Folder1 has files with duplicates elsewhere in folder2.
The files in folder1 should not be touched. However, the duplicates of the files in folder1 that are found in folder2, should be deleted.

However... folder2 may also have duplicates of OTHER files (i.e. other files than those of in folder1).
Those should remain in place, I will do that separately.

Example:
Folder1\sub folder\sub subf folder: SomePDF123.pdf
Folder2\sub folder: SomePDF123.pdf <-to be deleted
Folder2\sub folder\sub folder: otherduplicate.txt
Folder2\sub folder: otherduplicate.txt <- this will be done separately

So, first only delete duplicates found in folder2, being the duplicates of files in folder1
(folder1 should remain untouched).

How to proceed?

Thanks!

Set Folder 1 to "Protected" and "Find Duplicates->Master"
The Protected will stop you making files in Folder 1. The Master setting means that only files which duplicate this folder will be matched in other folders.

You can set Folder 2 to 'Find Duplicates->External only" though it shouldn't make a difference as long a Folder 1 is set to 'Master'

Thank you very much indeed!

I'll give it a try later.

Initially I messed up things: folder1 untouched, but folder 2 all duplicates are deleted, but that was not correct of course.
So I am restoring folder2, from a backup.
Takes a while ...

Update: Actually try setting Folder 1 to External Only+Master - this will stop it finding duplicates that are within folder 1 only, giving you less files to sort through.

Thanks - well, actually I went on to do the first suggestion.
I believe that went fine, but am still busy with it.
(Something else came up, so I'll finish it tomorrow)

Just to say thanks again.

Things worked out just fine!
Frankly, I wouldn't have figured this out myself.

Best regards and keep up the good work.
