claude-code - 💡(How to fix) Fix [BUG] Cowork: Folder does not support UNC under Windows [3 comments, 4 participants]

Error Messages/Logs

TL;DR

The issue can likely be resolved by using a mapped drive letter instead of the UNC path for the network folder.

Guidance

• Verify that the network folder is properly mapped to a drive letter in Windows, as this may allow Claude to access it without complaining about UNC paths.
• Try using the mapped drive letter in the path instead of the UNC path to see if this resolves the issue.
• Check if there are any configuration options in Claude or Cowork that allow specifying the path format or supporting UNC paths.
• If the issue persists, consider reaching out to the developers or searching for updates that may address this regression.

Example

No code snippet is provided as this issue seems related to configuration or path handling rather than code.

Notes

The solution may depend on the specific configuration of the Windows environment and how network folders are handled. This approach may not work if the UNC path is required for other reasons.

Recommendation

Apply workaround: Use a mapped drive letter instead of the UNC path, as this is a simple and non-invasive change that may resolve the issue without requiring updates or code changes.
