Product
OneDrive
Device & OS
Windows
Scenario
Attempting to access, sync, or open files within OneDrive, Documents, Desktop, or Pictures folders.
Observed behavior
Windows displays an error stating 'The file or directory is corrupted and unreadable,' blocking access to the files and folders.
Before you start

Before attempting complex software fixes, ensure your local C: drive has sufficient free storage space, as a completely full drive can cause this exact error.

Solution 1Recommended

Free Up Space on Your Local System Drive (C:)

A full C: drive can prevent Windows from functioning correctly, causing synced folders and shortcuts to appear corrupted or unreadable.

OneDrive relies on your local system drive to manage files and cache data. When the drive runs out of space, the file system cannot write new data, leading to corruption errors when attempting to access Desktop, Documents, or Pictures folders.

1
Check drive capacity

Open File Explorer, click on 'This PC' in the left pane, and check the storage bar under your Local Disk (C:).

2
Delete unnecessary files

Right-click the C: drive, select 'Properties', and click 'Disk Cleanup' to remove temporary files and empty the Recycle Bin safely.

3
Restart your computer

Once sufficient space is cleared, restart your PC to allow Windows to refresh the file system and restore access to OneDrive folders.

Focus on the OS First: Resolve the disk-space problem before attempting to troubleshoot the OneDrive application or Microsoft Office itself.

Frequently Asked Questions

Why does OneDrive say my file is corrupted and unreadable?

This error usually occurs when the local file system on your hard drive (typically the C: drive) is completely out of storage space, damaged, or suffering from bad sectors, which prevents Windows from reading the locally synced OneDrive folders.

Can I recover files if my local OneDrive folder is unreadable?

Yes. First, check if your files are intact by logging into OneDrive via a web browser. If they are available online, the issue is isolated to your local PC. You can download them directly from the web.

Will reinstalling OneDrive fix the corrupted directory error?

Reinstalling the OneDrive application typically will not fix this issue because the error originates from the Windows OS file system or local disk health, rather than a software bug within OneDrive itself. Address disk space and run a disk check first.
