Issue: How to fix "The directory is not empty" error 0x80070091 in Windows?

Hi. I was trying to remove some files from my C drive on Windows, and I received an error 0x80070091, which says, “The directory is not empty.” What does it mean, and why can't I delete my files?

Solved Answer

“The directory is not empty” error, coded as 0x80070091, is a Windows-based issue that users may encounter while trying to delete, move, or rename folders on their system. This error not only halts the intended action but can also be frustrating for users looking to manage their files efficiently. The problem can arise under several circumstances and is indicative of underlying issues that need to be addressed.

The error 0x80070091 occurs most commonly when users attempt to delete a folder that Windows believes still contains files or subfolders. Despite the folder appearing empty or even if it has hidden system files, the operating system restricts the action, presenting the user with this error message. This is usually a result of corrupted system files, faulty folder configurations, or conflicts with file permissions.

One might encounter the 0x80070091 error when trying to clean up disk space or during the process of transferring files from one directory to another. Additionally, it may occur when software applications try to modify folders during updates or installations but fail to do so because of this issue.

Although the error message does not provide specific guidance, there are multiple ways to resolve this issue. Solutions may involve using Command Prompt to manually delete the folder, adjusting folder permissions, or scanning and repairing corrupted system files. Additionally, checking for and terminating any background processes that may be using the folder could also be a viable solution. These methods will be detailed below this article for anyone looking to tackle the problem.

Fix 1. Perform Check Disk

The Check Disk utility scans and fixes errors on the hard drive, which can include corrupted files that may be causing the 0x80070091 error. This is an inbuilt tool in Windows that works by identifying and automatically repairing filesystem errors and bad sectors.

• Open the Start menu and type cmd.
• Right-click on Command Prompt and select Run as administrator.
• When UAC shows up, click Yes.
• In the new window, type in the following command and press Enter after:
  chkdsk c: /f
  (Note: use chkdsk c: /f /r /x command if you are using SSD as your primary partition)
• If you receive an error, type in Y, close down Command Prompt and restart your system.
• Wait until the scan is finished – you can find the results in the Event Viewer.

Fix 2. Restart Windows Explorer

Windows Explorer is the application you use to navigate files and folders. Restarting it can help resolve issues with file and folder manipulations, such as deleting a folder.

• Press Ctrl + Shift + Esc to open Task Manager.

Fix 3. Run SFC and DISM

System File Checker and Deployment Imaging Service and Management Tool can repair corrupted system files that might be preventing you from deleting a folder. These utilities are built into Windows and are known for their ability to fix various system-related issues.

  sfc /scannow

Fix 4. Adjust folder permissions

Sometimes, the issue is with the folder permissions that prevent you from making changes. Adjusting these can resolve the issue.

Sometimes, remnants of deleted files can conflict with the folder you are trying to delete. Emptying the Recycle Bin can resolve such conflicts.

Some background applications may be using files within the folder you are trying to delete, causing the error.
