Windows 8.1 and SSD - Managing Disk Space Bloat

January 24, 2016 at 12:14:18
Specs: Windows 8.1
Have a Windows 8.1 machine running on a 100GB SSD, where the SSD is only being used for programs. Also, 16GB RAM.

Got an Out of Memory error after installing a Brother Printer package, and found that the drive went from appx 50GB to nearly full. Ran WinDirStat, and now it has an "Unknown" file type with 40+GB of space allocated to it.

EDIT: Firstly, "Right click the drive > Properties" and run 'Disk Clean-up'. Let it clear the system files too. If by any chance there has been an aborted attempt at the Win 10 upgrade (or MS have foisted prep data on you) that can produce a lot of stuff.

If the space occupied by that unknown file type is 40GB then you should be able to go down the Windows Explorer tree and find what file or files is the culprit. There may then be a means of identifying what program it belongs to. There are other free programs which might assist:
I have not used any of them recently so check with the reviews. As always with free programs watch out for hidden goodies that have been ticked in advance. Use custom installs where possible.

You could uninstall the Brother Printer package to see what happens but 40 GB is a crazy size, even 1GB would be horrendous bloat. Have you looked in "Control Panel > Programs and Features"?

Always pop back and let us know the outcome - thanks

I had run Disk Cleanup several times, and it never worked (yes, ran as Admin). No, there was not an aborted win 10 upgrade. WinDirStat did show the "unknown" file type with all the bloat, but it could not do anything.

What finally worked was downloading CCleaner for Win 8.1, and it identified the files as temporary files and then nuked them all. Machine is much happier now! So is the user.

"Machine is much happier now! So is the user"

This will get rid of more.

Run Wise Disk Cleaner ( Run the 1st three tabs, left to right. I use default settings, leave boxes that are unchecked, unchecked ) Reboot when finished.

"and it identified the files as temporary files"
Sounds like your settings need adjusting.

Here are temp file settings for a normal user, adjust to suit your requirements.
Set Java to 100mb
All browsers, set to 50mb ( that's MB, not GB ) for temp.
Chrome is not so straight forward.
How to set Google Chrome cache to 50mb max temporary files.
With comps, there is always more than one way to do things, try this way.
Right click on the Google Chrome shortcut > Properties.
Copy & Paste this below after .exe" as per SS ( Screenshot )
NOTE: There is a space after .exe"
Click > Apply & then OK.
