automatic file compression

[Skybuck Flying]

Hi,

When windows xp is low on disk space it starts auto compressing files.

It was stupid enough to compress system32 and dllcache.

I found out dllcache is stupid in itself.

I guess windows xp is constantly decompressing dllcache to see if a dll has
changed.

This caused major performance degration.

I have deleted the dllcache with sfc /purgecache and set sfc /cachsize 1


Now... how can I turn off automatic ntfs file compression ?! when low on
disk space.

( I hate it and find it stupid how windows does all kinds of things
automatically, the user should be in control
not some little gremlins inside the os. It's windows xp professional, not
windows xp childesh. )
Bye,
Skybuck.

Hi,

Windows XP does NOT compress files on its own. the dllcache folder is always
compressed. The files and folders which have been unused for a long time get
compressed only after the Disk Cleanup utility is run and if 'Compress old
files' is checked.

Hi Skybuck,

Thanks for your posting and thanks for Anando's help. As Anando mentioned,
if "Compress old
files" is checked the utility will compress old files automatically. You
can run "cleanmgr /sageset" and uncheck the option. For more information
please refer to

Ok,

I run the tool like this:

cleanmgr /sagerun

or

cleanmgr /d c: /sagerun

It doesn't make a difference.

It will start saying:

"Calculating"

"Scanning: Compress old files"

So I can't even reach the options.

It better not be compressing my files haha !

Anyway.

I am now convinced this tool's purpose is backfiring.

Since I decompressed some system files and deleted the dllcache my system's
performance is much much much better.

The harddisk is a lot more quite and everything starts faster.

It doesn't seem the tool is compressing anything yet....

Since repeatedly clicking on C: reveals the same ammount of disk space
available.

Though it would be nice if there was an option to skip this scanning.

Or modify the registry ?

Thanks for the help

Well if what you say is true then this is clearly a performance issue

Since I now believe Windows XP was actually constantly using the DLLcache to
compare other DLL's to it, etc.

( Normally the word "cache" indicates something which is regularly used )

I am just glad I now have my system/harddisk performance back to normal

 

[Skybuck Flying]

Oh shit...

I read that article wrong

I thought it was the same option but without parameters.

I thought cleanmgr /sagerun ment the same as cleanmgr /d c: /sageset.

But that is a totally different option

Stupiddd

It's actually

cleanmgr /sageSET

and

cleanmgr /sageRUN

This option cleanmgr /sageSET allows one to bypass the scanning stuff and go
to the options

Skybuck.

 

[Skybuck Flying]

Hmmm well that is weird.

It says compress old files is off.

So how did it start compressing my files ?

Maybe I checked some option when it asked if I wanted to compress when I ran
out of diskspace I am not sure...

The option is off...

Huh... it's really weird ?!

Why does /sagerun start scanning and saying: 'compressing old files'

Etc..

It doesn't make sense...

Maybe because I cancelled it a few times... and now the boolean option is
'****ed up'.

Off means on ? and on means off ?

Anyway I'll just check it on and then check it off and see what happens

There are also many other nice options

Skybuck.

 

[Skybuck Flying]

Well it seems like a bug to me...

It still says: "Compress old files"

While I made sure the option was checked off.

It seems it is continueing a task from the last time it ran and when I
cancelled it, is that possible ?

Sageset:<number>

You set with /sageset:<a number> then run with sagerun:<a number>

EG

cleanmgr /sageset:0

Then to run Disk Cleanup with the options specified

cleanmgr /sagerun:0

Delete this Registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Compress old files

Type regsvr32 dataclen to undo.
