File Size Limitations

...

• For example, if the file URL in SharePoint is https://www.contoso.com/sites/marketing/documents/Shared%20Documents/Promotion/Some%20File.xlsx, the limit applies to “sites/marketing/documents/Shared Documents/Promotion/Some File.xlsx.”

• Likewise, if the file URL in OneDrive is https://contoso-my.sharepoint.com/personal/meganb_contoso%20_com/_layouts/15/onedrive.aspx?id=%2Fpersonal%2Fmeganb%5Fcontoso%5Fcom%2FDocuments%2FContracts%2FVendor%20Quotations/Some%20File.xlsx, the limit applies to “personal/meganb_contoso_com/Documents/Contracts/Vendor Quotations/Some File.xlsx.”

...

• Each segment of the path (a segment is a file name or folder name like “Promotion” or “Some File.xlsx” in the examples above) can't be more than 255 characters due to operating system limitations.

• The length of the OneDrive root folder (e.g. C:\users\meganb\OneDrive - Contoso) + the relative path of the file (up to 400 charscharacters) cannot be more than 520 characters.

• The organization name can be updated in the M365 admin center but that will not propagate to existing Sync relationships (only newly established ones). For existing Sync relationships to have the new organization name, users need to unlink and relink their accountaccounts.

SharePoint Server versions only support up to 260 characters for file and path lengths, Microsoft Excel and older Office version versions have a lower limit, see KB 326039Microsoft's troubleshooting page for details.

If you exceed any limits, you'll receive an error message.

...

Certain characters have special meanings when used in file names in OneDrive, SharePoint, Windows and macOS, such as "*" for wildcards, and "\" in file name paths. If a file or folder you’re trying to upload to OneDrive contains any of the characters listed below, it may prevent files and folders from syncing. Rename the file or folder to remove these characters before you upload it.

Notes

• To rename a file or folder in Windows, select it and press F2. To rename a file or folder on a Mac, select it and press the 'return' key. 

• Some organizations don't yet support # and % in names. If you're a global admin or SharePoint admin in Microsoft 365, see Enabling # and % Support on the SharePoint blog to learn how to allow these characters.

• For Office desktop win32 apps: If you're saving an Office file via the Backstage view to a OneDrive or SharePoint folder, you won't be able to save the file if the folder name contains ; (semicolon).

• If you're using Office 2010, you can't use "&" in file and folder names

...

For security reasons, a number of file names and extensions can't be uploaded since they are executable, used by SharePoint Server, or used by Windows itself.

Can I sync network or mapped drives?

You can't add a network or mapped drive as your OneDrive sync location. OneDrive doesn't support syncing using symbolic links or junction points.

Elevated privileges

OneDrive can’t be run with elevated privileges, and you will not be able to see OneDrive menu items within File Explorer. However, the per-machine sync app installation is helpful, especially for multi-user computers and when you don’t want exe files running from the user profile. See also Unable to share OneDrive files.

Although SharePoint can store 30 million documents per library, for optimum performance we recommend syncing no more than 300,000 files across all document libraries. Performance issues can occur if you have 300,000 items or more across all libraries that you are syncing, even if you are not syncing all items within those libraries.Notes

• If you are uploading, downloading, or moving a large number of files at once, you may need to wait an extended period of time before the sync process can complete. The desktop app showing “syncing” icon or displaying "processing changes" during this period is not necessarily an indication of a problem. You can always click the OneDrive taskbar icon to see the status of content that is in the process of syncing. To help reduce sync times, we recommend reviewing and possibly modifying your bandwidth settings before starting your upload or download. You can also read how to Choose which OneDrive folders to sync to your computer.

• There are other SharePoint limits on viewing a document library using the web that may affect how you structure your files in OneDrive.
