I am having the very same problem. I even re-installed
windows xp and it is still doing that. I tried the link
above also and it is still stopping on compress old
files. I let the program run all night last night and it
still didn't finish. I checked the task manager when I
woke up and it said it was still running and not the "not
responding" message so it seems like it is just running
in a loop. Can anyone help fix this for us? Thanks
You may want to try changing the age of the files that are tagged for
compression. Select "Compress Old Files" in Disk Cleanup and click
[Options]. The default age is 50 days, I have mine set at the maximum
500 days.
But really, compress old files is not worth the trouble turn it off.
On the other hand if you're having problems compressing files you may
want to run a scan disk and make sure your file system is healthy.
The compress files is heavily dependent on the speed of your processor;
so how much is it trying to compress and how fast is your CPU?
