6 Tested Methods to Fix “The Directory Name Is Invalid” Error in Windows
Fix 1: Check the Connection
There’s no need to panic if you encounter the “The directory name is invalid USB” error, as it’s usually caused by a simple connection issue. Start by safely unplugging the affected drive from your computer. Wait a few seconds, then plug it back in. If your PC has multiple USB ports, try connecting the drive to a different one. USB cables can wear out over time due to frequent use or bending, so switching to another cable is also a good idea.
Fix 2: Change the Drive Letter
One effective way to fix the “D the directory name is invalid” error is to manually assign a unique drive letter to the affected drive. The detailed steps are as follows:
Step 1: Write “Disk Management” into the taskbar search box, and then press Enter.

Step 3: Tap “Change,” assign an unused drive letter, and confirm.
Fix 3: Run the CHKDSK Utility
File system errors can occur if a drive is unplugged without being safely removed, experiences a sudden power loss, or develops bad sectors over time. If these errors are the culprit, you can try running a built-in Windows tool called CHKDSK. The following steps are how to fix the “The directory name is invalid USB” error with the aid of Check Disk:
Step 1: Right-click on the Windows icon followed by selecting “Command Prompt (Admin).”

Step 2: Expand the Disk drives section by double-clicking on it.
Step 3: Locate the problematic drive, right-click on it, and choose “Update driver.”
