3utools Failed To Access Folder Error Code 13 New < 2024 >

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.

This time I looked beyond standard permissions. I had a cloud-sync client running that locks files while syncing. I paused OneDrive and any other backup services. That solved a handful of issues in the past; here it helped too. Files started moving. But the error kept appearing intermittently, like a bird that landed, then flew away.

I opened my laptop, eager to back up my iPhone before an important update. I installed 3uTools — I’d used it before — and plugged in the phone. The app launched, scanned the device, and then showed a small, cold line of red text: “Failed to access folder — Error code 13.”
