A Microsoft file hosting and synchronization service.
Error code 0x80070070 indicates there isn’t enough free disk space to complete the installation.
To fix this, free up space on the system drive (usually C:) and then run the OneDrive installer again. Typical actions include:
- Uninstall apps that are no longer needed.
- Delete or move large personal files (videos, ISOs, installers) to an external drive or another partition.
- Empty the Recycle Bin after deleting files.
- If using Windows Update or other large installs at the same time, complete or cancel those first to release temporary space.
After freeing sufficient space, restart Windows and retry installing OneDrive.
If the error appears during a Windows upgrade that also installs OneDrive, the same cause applies: the PC doesn’t have enough space available to install the upgrade. Free space on the drive and try again.
