How to Repair Broken Folder Associations in Windows When you double-click a folder in Windows and it opens a command prompt, launches a random program, or throws an error, you are dealing with broken folder associations. This happens when the Windows Registry loses track of how to handle the standard directory file type.
Here is how to repair your folder associations and get your system back to normal. Method 1: The Registry Fix (Most Effective)
Broken folder associations usually stem from corrupted Registry keys. You can fix this by creating a registration (.reg) file to reset the default values.
Open Notepad: Press the Start key, type Notepad, and press Enter.
Copy the Code: Paste the following text exactly into the blank document:
Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\shell] @=“none” [HKEY_CLASSES_ROOT\Directory\shell\open] [HKEY_CLASSES_ROOT\Directory\shell\open\command] @=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,\ 00,5c,00,45,00,78,00,70,00,6c,00,6f,00,72,00,65,00,72,00,2e,00,65,00,78,00,\ 65,00,00,00 [HKEY_CLASSES_ROOT\Folder\shell] @=“” [HKEY_CLASSES_ROOT\Folder\shell\open] [HKEY_CLASSES_ROOT\Folder\shell\open\command] @=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,\ 00,5c,00,45,00,78,00,70,00,6c,00,6f,00,72,00,65,00,72,00,2e,00,65,00,78,00,\ 65,00,00,00 Use code with caution. Save the File: Click File > Save As.
Change File Type: Click the Save as type dropdown and select All Files (.).
Name the File: Name it folder_fix.reg and save it to your Desktop.
Run the File: Double-click folder_fix.reg. Click Yes when the User Account Control prompt appears, and click Yes again to confirm the Registry merge.
Restart: Restart your computer for the changes to take effect. Method 2: Use the Command Prompt
If you cannot run registry files, you can use the Command Prompt to re-register the Windows Explorer folder commands.
Press Win + R, type cmd, and press Ctrl + Shift + Enter to open an elevated Command Prompt.
Type the following command and press Enter:assoc folder=Folder
Next, type this command and press Enter:ftype Folder=%SystemRoot%\Explorer.exe /idlist,%I,%L Close the Command Prompt and test your folders. Method 3: System File Checker (SFC)
If a corrupt system file caused the association breakdown, the System File Checker tool can scan and repair it automatically.
Right-click the Start button and select Terminal (Admin) or Command Prompt (Admin). Type sfc /scannow and press Enter.
Wait for the scan to hit 100%. If it finds errors, Windows will repair them. Restart your PC afterward.
