I would like to manually trim my SSD in Windows 7. Is this possible?


Some SSD manufacturers have provided utilities on their websites that allow you to perform a "TRIM" like function manually. Check yours and see if it has that.


I wrote an article about TRIM; it also refers to a tool to manually TRIM your SSD: ForceTrim (download ForceTrim.zip, scan report at VirusTotal).

OCZ's forum is gone, but an archived version of Here's a tool to force-TRIM your entire drive is available. The source code is unfortunately lost.

  • The source code is unfortunately lost, but it appears that the tool writes <DRIVELETTER>:\_TRIM_, invokes TRIM on that and then removes it again. – Lekensteyn Oct 3 '14 at 12:05

    I have the source code if you need, I remember the original thread a few years ago and having checked the source code, it's made in Delphi. – hikari Oct 14 '14 at 8:03

    Please, would love to have that. – James King Mar 9 '16 at 17:43
  • @JamesKing I know this is ancient, but any chance either of you were able to find the source code for this? – Coldblackice May 14 '20 at 22:36
