    lost permissions/encryption problem


    I have just installed windows PRO 10/64 with all the updates.
    I saved my previous downloads folder to a USB memory stick.
    Now I can't access those files anymore as there is a gold padlock on each of them and message appears saying that I don't have permission to access those files; with attributes AE shown?
    No security tab appears for each file!
    Any ideas?
    Many Thanks!

    The problems that usually arise with encryption and backup programs when changing the OS/Operating System is that the encryption key used gets lost [probably was in the Registry which gets rewritten] or with backup programs the catalog gets lost, most likely for the same reason. Conventional logic says the files should have been decrypted before backing them up or copying to a different location. The backups usually have a means to recover such as a USB Thumb drive, years ago I had an MS-DOS backup from Colorado Memory that was a bootable 3.5" floppy disk containing a copy of the catalog, backed up to and restored from a tape drive and had to be recreated during each backup process.

    1. Follow this How to Add Take Ownership to Context Menu in Windows 10 tutorial (I prefer the Step 3 option - i.e. with pause - as you can see the results).
    2. Once installed, open your USB stick in File Explorer; right-click on a folder or file then choose Take ownership from the context menu.
    3. Accept the User Access Control (UAC) prompt by clicking on the Yes button.
    4. Rinse and repeat.

    Hope this helps...

    EDIT: Oops... I completely missed the "with attributes AE shown" bit (i.e. Authenticated Encryption) in the first post. Sorry...

    I only realised this later on when it was too late! - so, is there no way to recover?

    I've not yet found any surefire solution to decrypting when the key is lost. If a third-party program was used maybe the publisher/s will have help.

    I just get this now:

    "ERROR: File ownership cannot be applied on insecure file systems;
    there is no support for ACLs.
    Press any key to continue . . ."


    I think I did it right?
    cheers!

    I guess this means that the USB stick is not formatted using NTFS. Can you copy the files/folders from the USB stick to a folder on your HDD/SDD?

    Most USB Thumb drives come formatted as FAT32 up through 64GB, haven't gotten my hands on a larger one yet. Even the SD/SDHC cards and MicroSDXC cards are formatted FAT32. FAT32 is more compatible for use on storage devices with a number of Operating Systems. Bypassing the 32GB limit of Windows can be done on Linux systems with GPARTED program or using the Bootable GPARTED CD [free]. It can work with External USB drives also, I have a portable 500GB formatted as FAT32, Windows can read and write most FAT32 drives, it's the partitioning and formatting that has the limit.

    A limit of the SD/SDHC card formatting is if used in a digital camera and needing formatting/cleaning it should be done in the camera, not in a computer, even though the formatting seems to be the same.

    No! "access is denied"!
    It's only the the files in the 'moved' previous downloads folder that is affected, nothing else!
    i.e. even older files and even older 'moved' downloads folders are all OK, it's just the current/present downloads folder were access is denied; all the other folders and files are OK, i.e. from 2016 backwards.
    Many thanks!
