Error Codes

Hello! Michael. Thanks for the details.

This is a storage-related error, and it often appears when installing, updating, or reinstalling apps (like OneDrive) — Windows can’t complete the process because the drive (typically C:) is too full.

Here are the most Reliable Solution (Step-by-Step)

1. Free Up Space on C: Drive

The error 0x80070070 means “not enough disk space.” OneDrive needs at least 2–3 GB free to install.

Do these in order:

Empty Recycle Bin: Right-click Recycle Bin → Empty.

Delete temporary files:

Press Win + I → System → Storage → Temporary files → select all → Remove files.

Run Disk Cleanup:

  Press `Win + R`, type `cleanmgr`, press Enter.
  
     Select `C:` → Clean up system files → check all boxes → OK.
     
     Uninstall unused apps:
     
        `Win + I` → Apps → Installed apps → remove big programs you don’t use.
        

Aim for at least 3 GB free.

2. Fully Remove Any Old OneDrive Files

Sometimes leftover files block the reinstall:

• Press Win + R → paste:
  %localappdata%\Microsoft\OneDrive
• Delete everything inside that folder.
• Then press Win + R again → paste:
  C:\ProgramData\Microsoft OneDrive
• Delete that folder if it exists.

3. Uninstall Any Stuck OneDrive Install

Run this command to force-remove it (even if it’s not listed in Apps):

• Press Win + R → paste:
  %localappdata%\Microsoft\OneDrive\OneDrive.exe /uninstall
• Press Enter.
• Restart your computer.

4. Reinstall OneDrive (Fresh)

Download the latest official installer from Microsoft:

🔗 https://www.microsoft.com/onedrive

Run the installer as Administrator (right-click → Run as administrator).

• Sign in when prompted.

This 4-step process fixes 0x80070070 almost 100 % of the time because it clears space, removes corrupted leftovers, and ensures a clean install.

See if this helps. If you need further assistance, just let me know.

Best regards,
