OneDrive did an automated dump of a large number of files a few days ago but the files did not all get successfully backed up. My HDD still seems to indicate the files are occupying space, i.e. no big changes is HDD storage but many files on OneDrive are marked with a red circle and a white cross. I have cleaned up enough space on my HDD to accomodate the files but they don't seem to open from OneDrive. If i drag them back to the original directory can I recover the files?

    Hello. The red circle with a white X means OneDrive failed to sync that item. It does not mean the file is still in the cloud.

    In File Explorer's Details view, what size do the red-X files show, and does a copy pasted outside OneDrive actually open? On onedrive.com, do those same files open, and does Version history have an older copy?

    Also, what exact message does the OneDrive tray icon give for those files?

    Do not unlink the PC, empty the OneDrive folder, or run Storage Sense / Free up space until you have confirmed the important files open from the website or from the copies you made outside OneDrive.

    Do not drag the files back to the original directory as a recovery method. The supported recovery path is to restore from OneDrive first.

    Recommended steps:

    1. Let the current delete/move action finish if it is still in progress.
      • The safest option after a large accidental delete or move is to let the action complete, then undo or restore the files.
    2. Check the OneDrive website first.
      • Sign in to the OneDrive website.
      • Use Search everything at the top to look for the missing files.
      • Search by filename, description, tags, dates, or places.
    3. Check the OneDrive Recycle bin.
      • On the left side of the OneDrive website, select Recycle bin.
      • If the files are there, select them and choose Restore.
      • If the files might have been in Personal Vault, use Show Personal Vault items in the recycle bin.
    4. Check local storage on the PC.
      • Use File Explorer to search the computer for the files.
      • Also check the Windows Recycle Bin.
      • This is important because files saved outside OneDrive, or files not yet synced, may still exist locally.
    5. If many files changed at once and there is a Microsoft 365 subscription, use Restore your OneDrive.
      • Open Restore your OneDrive.
      • This can roll back changes to files and folders from the last 30 days.
      • Warning: files or folders created after the restore point are moved to the OneDrive Recycle Bin.
    6. If the files are found online but not downloaded correctly to the PC, avoid moving them manually until they are restored or fully available again.
      • Manual moves do not restore failed cloud copies.
    7. If the files are not found in search or in the OneDrive Recycle bin, recovery is usually not possible through self-service.
      • For personal OneDrive, deleted files can be restored within 30 days.
      • After permanent deletion from the OneDrive recycle bin, they cannot be restored.

    The red circle with a white cross indicates a sync problem, not a confirmed recovery path. The safest supported approach is: search OneDrive web, restore from Recycle bin if available, check local disk and Windows Recycle Bin, then use full OneDrive restore if eligible.
