No more problems - thnaks for helping.

Hi nukecad, thanks for your effort but I did all the steps you told me. And the solution of the "secret" is quite simple: The pagefile.sys is actual 12,5 GB. So that's the file Recuva is using to store its file lists and perhaps some information more about the scan. So, thanks again - to talk to you has been the right way to activate my brain... Best regards

Hi, and thanks for the quick answer. The 10 GB were gone after the scan. I'm looking for my space very strictly, that's the reason why I know it. And I'm using the Windows "Datenträgerbereinigung" and CCleaner "Health Check" very often to delete all obsolete files. I'm using Windows 10 Pro, 22H2. The scan runs on a HDD System Drive - Drive "C". And aside from that the space is reducing while Recuva runs. But if you don't think that Recuva is responsable for the lost of space, I will wait some days. Kind regards

Hi, I would like to know, where Recuva stores the Results after a deep scan. When Recuva finishes the scan ca. 10 GB of space are used permanently and I want to delete the files manual. Perhaps someone can help Thanks.
