Windows 7 free space decreasing

tipti · May 16, 2013

So in the last time i discovered, that may free space on my SSD is increasing. I tryed to serch for big files, make visible the system and hiddden files, no succes. If i look with WinDirStat or TreeSize free i get the result of 47 GB, but when i click on property of my C: - SSD, shows 86 GB. I have Corsair Force 3 SATA3 120GB SSD on Asrock fatality P67 proffesional MoBo with 16 GB RAM, AMD HD 6850 Graphic, I7 2600K processor. I turn off any shadow or recovery option that uses space, also virtual memory is off, my Documents, Mails, Games are all on another Harddrives ! Only instaled programs and utilities that are needed are on my SSD.
I also detect that my SSD is not fast as it should be ?

Corsair Force 3 SSD
1.3.3
msahci - OK
103424K - OK,
111,79 GB

I think that Offset allignement should be 4KB ?

Just want to confirm system restore is off as well.

Maybe a good idea to run chkdsk to ensure you do not have file system errors showing the drive as fuller than it is.

Windows does have lots of hidden files, but not nearly 40 gigabytes of them. Also note that you have a folder under your user name called appdata that may contain lots of files because many programs store files in that folder.

You alignment should be ok. The offset is because of the System Reserved partition at the start of the drive.

Hello
I switch everything off, whats uses space, system restore, page file, i have 16 GB RAM and i think its enough memory for WIB 7 professional. i done chkdsk also. i checked your idea about user folder appdata and it shows a little bit more then 3 GB. I also wondering why WinDirStat and TreeSize shows less and Windows properties function show more usage ?

Simply put some files are not meant to be access by us end users.

As an example. If you run windir stat as an admin the number will be a bit higher(85.5 vs 84.4 used in my case, Windows shows 91.4 used).

Some of the folders on the drive also show up as ZERO to users including the admin user and unless you find them all and change the security permissions, they will always show that way.

You still seem to have a massive amount of missing space. when you removed the hibernate file, you did it with the command prompt to remove the file? "powercfg -h off"

Have you run the built in Windows Disk Cleanup? and also did a cleanup of system files.

I have never seen THAT much difference.

I would get into that folder to take a look at what it contains. Mine is 14 megabytes and contains what seems like a copy of users folders(but without any data.).

This folder also has an appdata folder.
