What Does ‘Folder in Use’ Error Mean?
The ‘folder in use’ error is a common message users may encounter in Windows when trying to perform an action like deleting, renaming, or moving a folder. The error indicates that the folder cannot be altered because it is currently opened by another process.
Specifically, the error message will read something like: “Cannot delete folder: It is being used by another person or program.” This vague message does not specify what process or program is using the folder. Essentially, it means Windows has placed a lock on the folder, preventing it from being modified.
This lock is a protective measure to avoid potential corruption or data loss if the folder were to be changed while a program is actively accessing files within it. The system generates the ‘folder in use’ error to alert the user to close any programs that may be interacting with the folder before trying to alter it.
Common Causes of the ‘Folder in Use’ Error
The ‘folder in use’ error occurs when a folder or file within it is being accessed by another process, preventing you from modifying or deleting the folder. There are several common causes behind this:
Open Files
If a file within the folder is currently open in an application, Windows will prevent deleting or renaming the folder. For example, having a Word document open from that location can trigger the error when trying to delete the folder containing it.1
Running Programs
Programs that are currently running may be accessing files in the folder, causing the access error. This includes software running in the background you may not be aware of.2
Background Processes
Windows services, malware scans, search indexing, and other background processes can sometimes access files or lock folders while running, preventing you from deleting or modifying them.3
Files Being Accessed
One of the most common reasons for getting the ‘folder in use’ error message is having files in that folder open in other programs [1]. If a file within the folder you want to delete is currently open in an application like Word, Excel, Photoshop, etc., Windows will not allow deleting the folder since it contains files that are still being accessed. Trying to delete a folder while files inside it are still open is like trying to delete a book that someone is currently reading – Windows prevents this to avoid potential data loss or corruption.
To resolve this, you need to close any open files that are inside the folder you want to delete. Check the taskbar and open programs to see if you have any files open from that folder. Save and close those files, then try deleting the folder again. You may need to close and re-open the File Explorer window to refresh it. If you still get the error, there may be background processes or services accessing files in that folder, in which case you’ll need to identify and end those processes first before deleting.
Background Processes
One common cause of the ‘folder in use’ error is background processes running on your computer. System processes, indexing services, and antivirus software will often access folders and files while performing routine tasks.[1] These types of background operations usually happen automatically without any user interaction. As a result, you may try to delete or modify a folder that is currently being accessed by one of these processes.
For example, Windows Search indexing will regularly scan folders to keep the search index up-to-date. If the indexing service is running when you attempt to delete a folder, you will likely see the ‘folder in use’ error message. Similarly, antivirus software needs to scan files and folders routinely. So your antivirus could be scanning a folder at the same time you try to delete or move it.
The key is that while a background system process has a folder open, that folder cannot be deleted, moved, or renamed. Trying to modify the folder results in the ‘folder in use’ error.
How to Fix – Close Files/Programs
One of the most common causes of the ‘folder in use’ error is having files or programs open that are accessing the folder you are trying to delete or modify. To fix this:
- Open up Task Manager by pressing Ctrl+Shift+Esc on your keyboard.
- Go through the processes list and applications tab and close any files, programs or apps that you aren’t currently using or that could be accessing the locked folder.
- Pay particular attention to apps like File Explorer, command prompt windows, or text editors that may have the folder open.
- Restarting File Explorer after closing programs can also help release any locked folders.
Closing out unnecessary applications and processes gives Windows the ability to fully release the folder so it is no longer ‘in use’. Be sure to save any unsaved work before closing programs to avoid data loss.[1]
How to Fix – End Processes
One way to fix the “folder in use” error is to end any processes that may be accessing the folder through the Windows Task Manager. The Task Manager provides a list of currently running programs and services, allowing you to forcibly quit them.
To use the Task Manager to fix the error:
- Press Ctrl + Shift + Esc to open the Task Manager.
- Go to the “Processes” tab.
- Look for any process that might be accessing the folder, such as Windows Explorer or a program you had open with files in that folder.
- Select the process and click “End task” to force it to close.
- Try deleting the folder again.
Ending processes with the Task Manager will abruptly close any open files or unsaved work. But it can quickly resolve the “folder in use” issue when a background process or open program is preventing access to the folder. Just be sure to save your work first!

How to Fix – Unlock Folder
One option to unlock a folder that is in use is to utilize a dedicated unlocker utility. Tools like EMCO UnLock IT are designed to unlock files and folders that are locked by the system or other applications. These utilities work by ending processes and releasing file handles that are locking the resource.
Unlocker utilities like EMCO UnLock IT provide an easy way to unlock folders without having to end processes manually. They can scan for locks, display which processes are blocking access, and resolve folder in use errors with a single click. This allows you to quickly gain access to folders for renaming, moving, or deletion.
Using an unlocker tool is often faster and easier compared to manually closing programs or restarting your computer. They provide a targeted solution to unlock folders that get stuck in use. However, free unlocker utilities may have limited capabilities compared to paid solutions.
How to Fix – Restart Computer
One simple fix for the ‘folder in use’ error is to restart your computer. Restarting the computer ends all running processes and clears any locks on folders and files. This essentially provides a ‘clean slate’ for the operating system.
When you get the error message that a folder can’t be accessed or deleted because it’s in use, there is likely a background process or open program still accessing files in that folder. Restarting the computer closes all programs and stops any processes that may be locking the folder.
To restart your computer, click the Start menu and select the Power button near the bottom-right. Then choose ‘Restart’ to initiate a reboot. After the computer restarts, try accessing the folder again. In most cases, restarting will clear the error and allow you to delete or modify the folder as intended.
Restarting the PC essentially refreshes the operating system, which forces all locks and accesses on folders/files to be discontinued. It’s a quick and straightforward solution for ‘folder in use’ errors if you don’t need to keep any programs or processes running in the background.

How to Avoid the “Folder in Use” Error
There are some simple ways to avoid getting the “folder in use” error when trying to delete a folder in Windows:
First, make sure to close any files or programs that may be accessing the folder before trying to delete it. Sometimes a document, media file, or program executable may still be open with connections to the folder, preventing it from being deleted. Closing out of any open windows and applications that could be linked to the folder can free it up.
You can also disable indexing on the drive where the folder is located. The Windows indexing service runs in the background and scans files to make them searchable. This constant access can result in a “folder in use” error. Turning off indexing on that drive avoids this issue.
Finally, a simple restart of the computer will close all open files and stop any background processes that could be accessing the folder. Upon restart, you should then be able to delete the folder freely without any access conflicts. Just be sure to delete right away before opening anything else.
Following these tips should allow you to avoid the frustrating “folder in use” errors. Be sure to close programs, disable indexing if needed, and restart your computer before attempting to delete restricted folders.
When to Seek Further Help
In most cases, the ‘folder in use’ error can be resolved through the troubleshooting steps outlined above. However, if you have tried all of the recommended solutions and the error persists, it may be time to seek additional help.
Consult your IT department or support staff if you continue getting the ‘folder in use’ message after closing programs, ending processes, restarting your computer, etc. There may be an underlying issue that requires deeper technical expertise to diagnose and repair.
For example, your IT staff may need to dig into the operating system logs to identify the processes still accessing the folder. Or there could be a corrupted system file or registry issue preventing the folder from being unlocked. Professional IT support can use advanced tools and knowledge to get to the bottom of stubborn ‘folder in use’ errors.
Seeking help from IT professionals is especially recommended if the error occurs across multiple folders or drives, as that points to a wider system problem. Don’t spend hours fruitlessly trying to fix it yourself – consulting your IT team can save time and frustration.
With their help, the ‘folder in use’ message can be banished for good. Don’t hesitate to leverage their skills if you’ve hit a wall troubleshooting on your own.
