free space decreases when doing clean up

On Win 7 (also noted on XP) why when using the Windows cleanup tool does the actual total free space decrease? This seems very contra to what one would expect.
Thank you

 

Hi muruga, Is this using the Disk Cleanup in Properties?
When I delete a file on my computer, where does it go?

This is worth looking at. Neil.

 

Disc cleanup does not increase free space

Yes - that is the tool I am referring to
thanks

 

Have you had a look at the link I Posted?
I think it answers your question. Neil.

 

disc clean up does not increase free space

Yes I did. It refers to recycle bin - but when using that windows tool files are not dumped to recycle bin - so that does not apply to this .
thanks

 

Try CCleaner instead. For example:

I started with:

51,251,224,576 bytes free

Ran Windows Disk Cleanup which left me:

51,247,689,728 bytes free, which is actually a LOSS of

(3,534,848) bytes free. <-shrug->


I then ran CCleaner which left me:

51,267,108,864 bytes free, or

15,884,288 more bytes free than when I started.​

I observed the same events comparing CCleaner to Windows - hence my question.
thanks

 

This time:

Code:

Before: 92,673,099,027 bytes
 After: 92,673,275,237 bytes
        --------------------
  Diff:       +176,210 bytes
  
  
C:\Windows\Logs\CBS\DeepClean.log
Before:       0
 After:  37,242
        -------
SubTot: +37,242 
 
C:\Windows\Logs\DISM\dism.log
Before:  11,544
 After: 149,747
        -------
SubTot:+138,203
 
C:\Windows\servicing\Sessions\30361087_112133494.xml
Before:   <n/a>
 After:     765
        -------
SubTot:+176,210

 

Maybe this topic can be of some assistance...

Unexpected free disk space decrease?​

This may sound like a dumb suggestion, but I wonder if using CCleaner's Drive Wiper to overwrite free space would help any.

 

drive wiper is very good just takes LONG time - but yes thanks for reminder.

 

muruga, you're 2nd Heading made it clearer on what you were experiencing.
Thanks Doc for your clarification. Neil.

 

One pass should be sufficient.

 

1) Do a "dir c:\*.* /a /s>X:\before.txt "
2) Run cleanmgr.exe against drive C:
3) Do a "dir c:\*.* /a /s>X:\after.txt "
4) Use AJC Diff to compare your "X:\before.txt" and "X:\after.txt" files.

Note: "X:" - To keep from altering what's on drive C: with your "before.txt" and "after.txt" files, use a drive other than the one you cleaning up with cleanmgr.
