help Ghost files on my computer

[CosmicCube789]

I have had this problem for a while but I only just felt like attending to it now.
Cities Skylines and Bluestacks 5 Beta are both "installed" according to windows.
There is no trace of the folders actually existing on windows if I look through the directory that windows says it can't find for example C:\ProgramFiles\(somefilenamethatdoesn'texist)\something\Uninstaller.exe or something like that
 7.23 Gigabytes of my small 120Gb OS drive have been taken up by it.
Btw these are definitely(although unlikely to be anyway) not viruses because Cities skylines was downloaded from steam on my C drive  and Bluestacks 5 was there because I wanted to emulate a game and I am 100 percent sure that I got it from the normal site.
The space where the apps were is there but windows thinks something is there.

How do I delete the parts on my drive for the files so I can get my precious 7 gigabytes back?

treesize free or wiztree will show you where all the files on your system are, that should help you find where the space went.

Try uninstalling them from inside Steam. They might have gone into your SteamApps folder instead of their own folders inside C:\Program Files.

 

Tools like WinDirStat can give you a visualization of what's eating up your drive space.

 

Run Disk Cleanup.

 

If you have a desktop PC and you're really crammed for space, try disabling hibernation. Windows usually reserves a chunk of drive space equal to your system RAM so that it can dump the entire contents of RAM to disk. (That's hiberfil.sys.) Run this command from a run-as-admin command line:

 

powercfg /hibernate off

 

That will disable hibernation and get rid of hiberfil.sys.
