    I'd still be interested to know what happens with a false /dummy fff file.
    E.g. create a .txt file and change its extension to .fff then try to delete it.

    This was odd: can't recover from recycle bin:

    - but could cancel the dialogue.
    I did wait a while..

    If I create a txt file and change it into a fff it behaves normaly. Can be renamed, copied and deleted.
    If I rename a fff file on another machine (MAC) to a tif an copy it to my PC, I can open it in Photoshop and save it into another tif file, which then behaves normaly. The original file, that is now a tif however, behaves in the same manner than the fff files (also cant be renamed, copied or deleted). So I would guess, that it is somehow related to a raw file extension like the preview picture or any other raw data that is implemented in these particular fff file types.
    (in short: fff files are used as a camera-raw standard by hasselblad cameras and in my case a hasselblad scanner - but only the ones created by cameras are supported by default raw-converters - since the scanner has been discontinued, the software development and sopport has as well..)

    If you can move the files into a folder, try deleting the folder via the script in option seven in the following tutorial:

    You may learn more about what's going on by using e.g. Process Monitor

    and inspecting the log.

    Start the capture, note as exactly as you can the time when you click the file to start deleting it so you can look back at the log at the right time.

    Warning- the log can be huge- make sure as little is happening on your PC as possible before starting the capture.
    Filters can be applied to the log to eliminate background events for example: filters can be very technical.

    Tried the DOS prompt - It just freezes.
    Did you simply open a command prompt box when logged in, or did you boot to a command prompt and then try to delete the file? (E.g. via SHIFT + left click Restart and folowing the prompts).

    These two are very different.

    Hi, this problem is likely related to the Photos app- perhaps related to its album and indexing.

    Here's one way michael_miller_4g8agax0a5bfx resolved the same symptoms:

    A post above indicated that it was likely a permissions issue/being open somewhere in some other file, so I eventually traced it to likely relating to the Windows 10 'Photos' app and perhaps related to having a preview of the file (i.e. after I had opened a .fff file in Photos and could see the negative, if I closed it in Windows explorer it would show me a preview thumbnail of that photo, but not other 3f photos in the same directory that I hadn't specifically opened in Photos). I then uninstalled Photos app (instructions online) and also made sure to remove thumbnails when using the Disk Cleanup option - and this seems to have resolved the issue - I can now rename, move, delete at my hearts content.

    If all else fails you can boot into recovery mode and force delete just about anything at the command line. Alternatively, you can do the same thing by booting into a flash drive running Linux, then working through a suitable NTFS (or other file system) capable tool.

    I once failed to delete Windows files even on Linux running from a USB device..

    Have you tried uninstalling the Photos app? See my previous post where it solved the same problem for someone.

    Maybe that is not even needed. Maybe it is sufficient to define a different default app, based on the extension fff.
