Two days ago everything was fine. Today I can't view any of them. The actual jpg files have no header, according to Easeus support.

Windows 11

No viruses

Hard drive has no errors

Only update has been Microsoft's Virus Definitions

    There's not enough information in your question, even for a guess. Files don't suddenly become corrupted for no reason. If you have additional information to provide that might be helpful. It could be something that you did, since you're sure it isn't malware. Malware wouldn't do that anyway, since there's nothing in it for the attacker.

    Otherwise, I suggest showing your computer to a professional who can go through the software and try to figure out what happened.

    Hi Jim R,

    I understand how concerning it is to suddenly lose access to such a large number of photos, especially when everything was working just a couple of days ago.

    To narrow this down further, could you confirm:

    1. Are all affected files located on the same drive or folder?
    2. Were these files synced with OneDrive or any NAS/external drive?
    3. Did anything else happen recently (e.g., file transfer, cleanup tool, disk repair)?

    In the meantime, please try the following checks:

    1, Test files on another device/application

    • Copy a few affected JPG files to another PC or phone
    • Try opening them using a different viewer (e.g., Photos app, Paint, or a web browser)

    Confirm whether the files are truly corrupted or just unreadable on your system

    2, Check previous versions (if available)

    1. Right-click a folder that contains the JPG files
    2. Select “Properties” > “Previous Versions”
    3. Restore a version from before the issue occurred

    This relies on File History or System Protection being enabled

    3, Check OneDrive or backup sources (if used)

    If your Pictures folder was syncing, older intact versions may exist

    4, Run system file integrity checks

    • Open Command Prompt (Admin) and run: sfc /scannow
    • Then: DISM /Online /Cleanup-Image /RestoreHealth
