I own this computer but I can not see what is inside hidden files. I thought the owner had full access

    Hi Douglas Swanson,

    Being the owner of the computer does not necessarily mean every hidden or protected file can be opened, since Windows can apply separate permissions or protection to individual files and folders.

    Since the visibility and ownership steps have already been covered, could you provide:

    • The exact path of one folder/file you cannot access, for example C:\Users\...\ (please note to remove any personal information)
    • The exact message or error you receive when you try to open it.
    • Whether the files came from this Windows installation, another PC/drive, or another user account.

    This should help determine whether you're dealing with permissions, protected system files, encryption, or files associated with another Windows profile, without making unnecessary changes to system folders.

    Once you share those details, we can narrow down the safest next step.

    Enable Hidden items in File Explorer first; owning the computer or being an administrator does not automatically make hidden files visible or grant unrestricted access to every file.

    Show hidden files

    • Windows 11: Open File Explorer → View → Show → select Hidden items.
    • Windows 10: Open File Explorer → View → Options → Change folder and search options → View → select Show hidden files, folders, and drives → OK. ^1^

    Hidden files should then appear, usually with faded icons.

    If the files appear but say “Access denied”

    Visibility and access are separate. Windows gives each file or folder its own owner and access-control permissions. The owner can change permissions, but ownership itself is not the same as having Full control. ^2^

    For a personal data folder that belongs to you:

    1. Right-click the folder → Properties → Security → Advanced.
    2. Next to Owner, select Change.
    3. Enter your Windows account name → Check Names → OK.
    4. If appropriate for all contents, select Replace owner on subcontainers and objects.
    5. Select Apply.
    6. Return to Security → Edit, select your account, and grant the permissions required—such as Read or Full control. ^3^

    Do not take ownership of an entire Windows, Program Files, recovery, or system folder merely to inspect it. Some hidden files are protected operating-system data; recursively replacing their permissions can interfere with Windows services. Apply ownership changes only to a specific personal folder whose contents should belong to your account.

    If the files are encrypted, owned by another Windows installation, or stored under another person’s profile, changing visibility alone will not provide access. The exact folder path and the message shown when opening it are needed to distinguish those cases.
