I dove into 3uTools logs and Windows Event Viewer. The log hinted at an access denied result when trying to create a temporary folder under C:\Users<me>\AppData\Local\Temp\3uTools. Checking that folder, I found a leftover temporary directory from an earlier failed session, owned by SYSTEM, inaccessible to my account. I deleted the orphaned temp folder and created a new empty temp folder with correct permissions.
If you’re seeing in 3uTools when trying to access a folder — usually during backup, flash, or file management — it means the application does not have permission to read or write to that specific directory.
