Amount removed by Cleaner

[grits2]

Sometimes the amount removed is larger than the analysis, why?

 

Just a bit ago the analysis was 1.11MB but it removed 3.86MB.

Which OS & CCleaner version?

 

Btw. I've also noticed this and that the analyze/clean results differ sometimes.

Two Possible Causes

• Temp files are being created between the analysis and the time that the cleaner finishes with the section they are cleaned in.
  
• CCleaner's Analysis is a Rough estimate (maybe, at a guess, based on "size" blue pen) while the clean is an exact amount of space freed (maybe based on "size on disc" red pen )

Actually, Nergal, I always thought that the blue pen = the actual size of the file, while the red = the disk space taken up by that file.

 

For instance, if you have two sectors at 512 KB & that = 1,024 KB (1 MB), then if you copy a file that = 1,500 KB, then it will take up yet another 512 KB sector & = 1,536 used because of not placing another file at the end.

 

I am not 100% sure if this is correct, however, so I could be wrong.

Sorry Speedfast, I think you may be a bit off here.

Our moderator has shown us a file with contents that are only 10.1 KB, but the system only provides space in 4 KB chunks so the size taken from the disk is 12 KB

Size on disk can also be less than file size if Windows has compressed it.

 

Sorry Nergal but I cannot resist a tut tut - you keep files instead of links on your desktop

 

Back on Topic

 

I hate Flash so much that I include the root of all evil in my INCLUDE.

I also use Winapp2.ini which hits some of the FLASH that I hate.

 

Analyze adds up the sum total of Flash targeted by both Winapp2.ini and INCLUDE.

Results only sees the actual deletion so that is a smaller amount.

 

Also, sometimes after a Clean I analyze again, and extra items may be present which were absent 10 seconds earlier.

If only they had been available 5 seconds earlier then Analyze would still have not seen them,

but Clean would have found and zapped them.

I think Thumbnail Caches is one of these things.

[Augeas]

SF, in the vast majority of cases a disk sector is 512 bytes, not 512 k, and the default unit of data allocation is 8 sectors, a cluster of 4k. Which is why Nergal's file is allocated as a multiple of 4k. (Very new disks may have larger sector and cluster sizes).

 

I would think that CC's total removed is the allocation size, as that is what is actually freed. I have never noticed any difference myself between the analysis and the removed size.

 

Why do some see a difference? I don't really know, maybe the clean process digs a little deeper than the analysis, or maybe Nergal is correct. It is curious, but not, I think, a worry.

Sorry Nergal but I cannot resist a tut tut - you keep files instead of links on your desktop

rarely and only ones I need quick access to and plan to delete soon (i.e. a temporary spreadsheet listing Mp3s without album art)

 

Please everyone don't going running off with my postulation, that's all that it ever was.
