    How to Encrypt or Unencrypt Offline Files Cache in Windows


    Offline Files is a feature of Sync Center that makes network files available to a user, even if the network connection to the server is unavailable.

    Users can use offline files (if always available offline to keep a copy of the files stored on the network on your computer. This allows users to work with them even when they are not connected to the network or a server is unavailable. The next time the user connects to the network or the server is available, their offline files on your computer will automatically sync to the network files on the server to update.

    Users can encrypt the contents of their Offline Files cache on the computer to protect it from unwanted access.

    This tutorial will show you how to encrypt or unencrypt the Offline Files cache for your account or all users in Windows 7, Windows 8, and Windows 10.

    In Windows 8, the offline files feature is only available in the Pro and Enterprise editions.

    In Windows 10, the offline files feature is only available in the Pro, Enterprise, and Education editions.

    Windows XP file encryption

    My suggestion to you is to look into what kind of encryption the program used, and look for a way to break that type of encryption. Sorry I can't say a specific program for sure.

    Reduce offline files cache size

    Hi ZigZag, thanks for the reply.

    Actually it turns out I have misunderstood the concept of offline files - it actually
    does copy the files to the server, and the error simply indicates that it failed to copy the files back from the server into the offline cache. TIL...

    My initial question (how to reduce the offline files cache) is now slightly different, since I would actually like to assign as much cache space as possible to one network storage, but keep a smaller limit on the other network storage. I have started a new
    thread with that question here:
    http://answers.microsoft.com/en-us/windows/forum/windows_10-files/managing-offline-files-cache-on-a-per-folder-basis/b4e03410-bc1f-436d-9252-c1ce562d0d11?tm=1466672260879

    On another note, why is this not a consumer question? I would simply like to configure the offline files cache size on an end user's computer.

    encrypted files

    Hi Iman,

    Error message 0x80071771 means that you need to restore the file encryption key in order for you to decrypt the encrypted files. On the other hand, you can still try these steps and see if it will work:

    • Right-click the file or folder that you want to decrypt.
    • Click File ownership and click Personal.

    Feel free to contact us if you need assistance with Windows.
