Re: Compression reduces free space

Where are you getting your fee disk space information from?

In Windows XP most users looked at the figures in Windows Explorer. If users
used third party file managers they also got their figures from the same
source as Windows Explorer. The figures never reconciled because the results
of file compression were ignored. Instead of using size on disk the file
size figures were taken. I would not be surprised if the same situation
applies in Vista except that you have the added complication of shadow
copies referred to by DL.

Are you using any third party backup programmes?

Have you run Disk CleanUp?

Start, All Programs, Accessories, System Tools, Disk CleanUp to empty the
Recycle Bin, remove Temporary Internet Files etc. Also select the More
Options tabs and remove System Restore Points and Shadow Copies. Please
advise what affect this has on free disk space?

Gerry -

Thanks to you and DL for the reference to removing shadow copies - I ran
this and the computer got back up to 22.8 GB!

And to R.C. - thanks for your info. It's always interesting to hear about
the technicalities, although I find it a bit hard to follow -

Glad to be able to help.

It would appear likely that you will need to include their removal in your
routine housekeeping to maintain a reasonable amount of free disk space.

DL

22gb free is still borderline and unless you have a large ammount of data
something else is consumming space.
If you are creating backups on this drive there is little point since if the
drive goes west so do your backups.
You perhaps should be considering installing a second drive.
