Here i am talking about a manual, highly detailed approach to deleting junk files in Windows 11 by directly targeting specific system and user temporary folders. Here's a breakdown of each part:

Manual Folder Cleanup 

This method involves directly accessing and deleting junk files in Windows 11 and applications use to store temporary data. Doing so can free up disk space and help improve system performance. 

How to do it:
Press Win + R to open the Run dialog, then paste the following paths one by one and delete the contents inside:

1. %TEMP%
Path: User temporary files folder (C:\Users\<YourUserName>\AppData\Local\Temp)
Purpose: Stores temporary files created by Windows and applications during operation.
Cleanup: Deleting these files can free up space and remove leftovers from applications or processes that might not have cleaned up after themselves.

2. C:\Windows\Temp
Path: System temporary files (C:\Windows\Temp)
Purpose: Stores temporary files used by Windows during system operations, updates, or installation processes.
Cleanup: Removing files here can help clear up space used by system processes, especially after updates or installations.

3. %LOCALAPPDATA%\Temp
Path: Local AppData temp folder (C:\Users\<YourUserName>\AppData\Local\Temp)
Purpose: Stores temporary data specific to certain applications.
Cleanup: Similar to the user temp folder, clearing these files can free space used by app-specific temporary data.

4. %LOCALAPPDATA%\Microsoft\Windows\INetCache
Path: Internet cache for IE/Edge (C:\Users\<YourUserName>\AppData\Local\Microsoft\Windows\INetCache)
Purpose: Stores cached web content to speed up browsing.
Cleanup: Clearing cache can free disk space and resolve browsing issues caused by corrupted cache data.

5. %LOCALAPPDATA%\Microsoft\Windows\WER
Path: Error reports (C:\Users\<YourUserName>\AppData\Local\Microsoft\Windows\WER)
Purpose: Stores crash dumps and error reports for Windows Error Reporting.
Cleanup: Deleting these can free space accumulated from crash logs, especially if you're troubleshooting.

6. %LOCALAPPDATA%\Microsoft\Windows\DeliveryOptimization\Cache
Path: Windows Update Delivery Optimization cache (C:\Users\<YourUserName>\AppData\Local\Microsoft\Windows\DeliveryOptimization\Cache)
Purpose: Stores cached data for Windows updates, used to optimize update delivery across devices.
Cleanup: Removing these files can free space, especially if updates have already been installed.
