    Are you trying to encrypt a file that is placed on an external device? Cipher only supports NTFS.

  • I'm trying to encrypt two txt documents using cmd well known Cipher command but it returns Request not supported.

    For reference,

    My HDD's file system is NTFS and I've already run sfc /scannow and it is internal disk drive. (System File Checker tool for fixing any corrupt file if any)

    Such that all the above has not worked. Please help me in this case.

  • Hi,

    I can run this commands well on my 1709 Windows 10 Enterprise.

    Please try examples like these:

    To use cipher to encrypt a subfolder named May in a folder named MonthlyReports, type:

    cipher /e monthlyreports\may

    To encrypt the MonthlyReports folder, the January through December subfolders, and the Manufacturing subfolders within the month subfolders, type:

    cipher /e /s:monthlyreports

    To encrypt only the Marketing.xls file in the May subfolder, type:

    cipher /e /a monthlyreports\may\marketing.xls

    To encrypt the Marketing.xls file, the Maintenance.doc file, and the Manufacturing subfolder (located in the May folder), type:

    cipher /e /a monthlyreports\may\ma\*
