    I'd suspect interference from an anti-virus program. Can you check if these users have an AV installed, and whether the problem disappears
    if they remove it.

    Thanks, I'll check that one out.
    I've had this, and initially thought that I had too many files open

    Actually, when reading other answers, I realized I have a regular

    How the issue got resolved? I am getting same error randomly

    In my case (writing 6000 files via a Java program), the problem seemed to be Dropbox synchronisation somehow blocking the file writing. Paused Dropbox synch, error gone.

    the problem seemed to be Dropbox synchronisation somehow blocking the
    file writing. Paused Dropbox synch, error gone.

    Sounds like a reason :

    The full text corresponding to this code is "The requested operation cannot
    be performed on a file with a user-mapped section open."
    [/quote]

    https://groups.google.com/g/comp.os.ms-windows.programmer.win32/c/plQmyXqAeOI

    IOW, if DropBox is has a file open using a memory-mapped file method than
    the writing to that same file using normal means is likely disallowed (the files contents on the disk and the already-present "view of file" - cached
    file contents - would mismatch).

    One possible solution (no idea if you can delete a file that is
    memory-mapped though) could be to delete the target file before writing a fully new one.
