On the Automatic add page in Preferences the warning says "WARNING: Files in the above folder will be deleted after being added to calibre."

Reading the warning I thought that only books actually added would be deleted. That the rest would be left alone. I dumped a heap of books into that folder, said don't add the duplicates that it found and it looks like calibre deleted EVERYTHING in that folder after processing (again... even the ones it did not add to my Library). To make matters worse it didn't send the removed files to the Windows Recycle bin.

In this case a LOT of the dupes were false positives caused by "Title - Author" and "Author - Title" flips, "Last, First" and "First Last" flips, and books with "&" in the Title (being read as Authors) as well as actual duplicates.

Did I miss a configuration somewhere? How do I get calibre to not delete books it didn't add (for any reason) or at the very least to get it to use the Recycle Bin?

Thanks!

P.S. For whatever it's worth I very much would consider this a bug and at the very least bad UX. First, the warning is NOT clear, in my opinion, that non-added books are also deleted. Second, the files should NOT have skipped the Recycle Bin. Not in this day and age where storage is backed by NVMe and SSD with TRIM enabled by default on Win10 and 11.

I do realize this behavior might be to avoid having files linger in the import folder but an option "Remove permanently" or "Send to Recycle Bin" would be one way to handle this. Another would be to automatically create a sub-folder "Unable to Add to Library" (or whatever...) and move files to that.
