There are certain technological limitations in OneDrive and SharePoint. Note that unless stated, the limit applies to both OneDrive and SharePoint.
Storage Limits
OneDrive - 1TB
SharePoint - 25TB across 30 million files.
File Size and Path
250 GB - File upload limit. Applies to each individual file uploaded to Microsoft Teams Files tab, SharePoint document libraries, and OneDrive folders.
The entire decoded file path, including the file name, can't contain more than 400 characters. Learn more: OneDrive - File Path Limit or SharePoint - File Path Limit
Moving and Copying files
No more than 100 GB total file size
No more than 30,000 files
Each file must be less than 15 GB
If you need to conduct a transfer larger than this, you will need to use File Explorer (Windows) or Finder (macOS). Please reach out to techsupport@uconn.edu if you need help or have questions.
OneDrive App - Sync
OneDrive has a “soft limit” of 300,000 items. This means sync tasks of more than 300,000 files will work, but will greatly slow down the application and possibly cause it to crash.
