DLL Files Automatically Deleted? Prevention & File Recovery Here!

DLL files are crucial for the program to run. This tutorial will guide you step by step to resolve the "DLL file automatic deletion" issue, providing an effective way to recover deleted DLL files and prevent this problem from happening again.

Automatically delete DLL files

A DLL (Dynamic Link Library) is a library file containing code and data. For Windows operating systems, most operating system functions and programs rely on DLL files. Using DLL files helps the operating system and programs load faster and reduces the computer's disk space usage.

However, many users report that their DLL files are always automatically deleted, causing the program to fail to run. Next, we'll cover how to recover deleted DLL files (if Windows automatically deletes DLL files), and what you can do to prevent this issue from happening again.

How to recover deleted DLL files

Method 1: Check the recycling bin

If your DLL file is missing, you can open the Recycle Bin and check if the deleted DLL file is there. If yes, you can select the target DLL file, right-click and select Restore to restore it to its original location.

Method 2: Use MiniTool Power Data Recovery

If the Recycle Bin is grayed out, corrupted, or has been emptied, you cannot find the deleted DLL file in the Recycle Bin. In this case, to recover lost DLL files, you need to use professional data recovery software.

We highly recommend MiniTool Power Data Recovery. This file recovery software can effectively recover deleted WordPad documents, DLL files, videos, Word documents, Excel files, PDF files, audio, etc. The free version supports free file scanning and preview, as well as 1GB of free file recovery.

Step 3. Select the desired DLL files, and then click the "Save" button to select the desired location to store them.

How to prevent Windows from automatically deleting DLL files

"Automatic deletion of DLL files" is usually caused by antivirus software (such as Windows Defender) or storage space aware features. To prevent DLL files from being deleted automatically, you can try adding trusted DLL files to Windows Defender exclusions, turning off antivirus software, or disable storage space awareness.

Method 1: Add DLL file to Windows Defender exclusions

To prevent Windows Defender from deleting files in Windows 11/10, you can add the target file to the exclusions.

Step 1. Press the Windows I key combination to open the settings.

Step 2. Click Update & Security > Windows Security . In the right panel, click Virus and Threat Protection .

Step 4. In the new window, scroll down and click Add or Remove Excludes under Excludes . If the UAC window for requesting permissions appears, you need to select Yes .

Step 5. Click Add Excludes > File Type . Then, enter ".dll" in the input box and click Add . Additionally, you can repeat these steps to add the ".exe" file extension to the exclusions.

Finally, your DLL file should not be automatically deleted by Windows Defender.

Other antivirus software may also delete your DLL files. To prevent this, you might consider disabling these antivirus software.

Method 3: Disable storage space awareness

Storage space awareness is a useful tool that can help you automatically free up disk space on your PC. It may be the reason why the DLL file automatically deletes itself. To disable it, you can do the following:
