File length restriction for access sharepoint files in windows while amking shortcut is very difficult

The limit cannot effectively be increased for Windows File Explorer and Office desktop apps in this scenario.

Key limits:

1. Windows File Explorer: 260 characters for opening, renaming, and moving files.
2. Office desktop apps on Windows: 256 characters (260 UTF16 WCHARs).
3. OneDrive and SharePoint in the cloud: 400 characters.
4. OneDrive sync: 520 characters total, which includes the local synced path plus the OneDrive root folder.

Why the registry change did not help:

• Windows can support longer paths only when long path support is enabled.
• But File Explorer and Office desktop apps do not currently opt in, so enabling the policy or registry setting alone does not remove the 260-character limit for most users.

Practical ways to work around it:

1. Shorten file and folder names
   • Reduce long descriptive names.
   • Shorter names leave more room for folder depth.
2. Flatten the folder structure
   • Deep nesting quickly consumes the available path length.
   • Move frequently used files closer to the root.
3. Use OneDrive Files On-Demand
   • Browse files in File Explorer without downloading everything.
   • When a file has a long path, open it in the browser, where the 400-character cloud limit applies instead of the 260-character desktop limit.
4. Rename from the web
   • If a file or folder path is too long to manage in File Explorer, rename it in OneDrive on the web or in the SharePoint site.
   • After the path is shortened enough, it can sync normally to the desktop.
5. Be careful with SharePoint shortcuts and synced libraries
   • Adding a shortcut to a deeply nested shared library or Teams channel folder can quickly exceed the local Windows limit.
   • Sync only a subfolder if possible, or shorten the shortcut name in OneDrive.
6. Check the OneDrive root folder length
   • A work or school sync path such as C:\Users\Name\OneDrive - Organization Name\... already uses many characters before the actual file path starts.
   • A longer organization name leaves fewer characters for folders and file names.
7. Use OneDrive sync notifications
   • If OneDrive detects a path that is too long, it shows a notification identifying affected files.

Important behavior to expect:

• A file may work in SharePoint or OneDrive on the web but fail in Windows Explorer.
• If a synced file’s full path exceeds 520 characters, OneDrive shows a path is too long notification and the sync client quits until the over-limit item is fixed.
• Individual file or folder names can be up to 255 characters, but the full path can still fail because of nesting.

For migrated on-premises data, the supported fix is usually to shorten names, reduce nesting, sync a smaller subfolder, or use the web for long paths. There is no supported setting that makes File Explorer use the same 400-character limit as SharePoint Online.
