TOTAL ~ 116 GB
As you can see, if I sum up all the space amount from my Files and Folders, I get a total amount of approximately 116 GB. However, Windows Explorer tells me that the total used space for (C: ) is 195 GB, and that I have only 6 MB of free space, meaning that my Windows space is almost full. This morning, I still had about 2 GB of free space.
This is really strange. 1. Why this discrepancy? 2. What is this process that runs in the background and eats up all my space and how to eliminate it?
Have you checked the amount of space allocated to system restore? If you turn off system restore and then restart your computer you will see how much it uses.( check disk space before and after) Dont forget to turn it on again after. If it is excessive just alter the amount of space to give it.
CCleaner found about about 86 GB of files to be removed, mainly:
~ 84 GB in System - Temporary Files (C:\Windows\TEMP) (!)
~ 2 GB in the Google Earth cache
So, you were entirely right: I had LOTS (!) of temp files.
What is weird is that those 84 GB of Windows temp files were in C:\Windows\TEMP (before I removed them with CCleaner). However, Windows Explorer had previously shown me (and still currently shows me) an amount of 11.3 GB in the C:\Windows folder ! Very misleading ! Any idea why WE did not take into account the space amount in the TEMP subfolder? Is this a known bug, or is there something wrong in my config? (If WE had given me the correct space amount in the Windows folder, I think I would have been able to find the presence of all these temp files data...)
I guess I will have to monitor my disk space usage in the next few days/week to make sure that it does not increase too fast, and use CCleaner from time to time...
Many thanks for suggesting to use this CCleaner! Looks like a great tool. You have been very helpful !
