Hello.
If the system hard drive (C:/) has little free space, it is possible to free up space by deleting temporary files using FRST.

Warning!

The following folders will be emptied:

  •  - Windows temporary files.
  •  - User's temporary folders.
  •  - Caches, HTML5 storage areas, cookies, and history for browsers analyzed by FRST, except for Firefox clones.
  •  - Cache of recently opened files.
  •  - Discord cache.
  •  - Java cache.
  •  - Steam HTML cache
  •  - Thumbnail and icon cache of Explorer
  •  - BITS transfer queue (files qmgr.db and qmgr*.dat)
  •  - WinHTTP AutoProxy cache
  •  - Recycle Bin
  •  - DNS cache


Here’s how to do it:
Download FRST https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/ and save it to the desktop.



Procedure to delete temporary files:
Note: If System Restore is enabled on the PC, a restore point will be created.

1- Open FRST as an administrator by right-clicking on FRST and selecting Run as administrator
2 - Copy the entire script that is in the box below:

Start:: CreateRestorePoint: CloseProcesses: EmptyTemp: End::


3- Once the script is copied, click on Fix, FRST will automatically take the script from the clipboard.



Let the fix complete; once it’s finished, you will be asked to restart the PC, see below:


Once the computer is restarted:
4- There will be a Fixlog file on the desktop indicating the amount of data deleted.
Example of a report:

================================


Once the temporary files are deleted, uninstall FRST:
To uninstall FRST, rename the FRST file to uninstall, then once the file is renamed, open it; the uninstallation will occur automatically upon restart of the PC.
