Disk Cleanup use up CPU resources and could not finish cleanup process.

Disk Cleanup use up CPU resources and could not finish cleanup process.

On the pop up disk cleanup calculating processing message window, it showed Scanning: Compress old files

On the task manager window, I can see cpu usage is 99% over and performance window showed the curve stay in top all the way.

The environment is in enterprise WAN and department LAN with SAP, Oracle, SQL Server and XP

compression algorithms are heavily cpu intensive and will cause that to max out, that is definitely normal.  Although disk cleanup is not a good approach to clean up data on your server.  You must manually determine which files can be compressed/deleted as letting windows do that simply by the 'last accessed' info can be very troublesome and degrade performance SEVERELY.  I strongly suggest that you not use disk cleanup on a server.  Also I would check the following (in order)

1) is the drive in a Raid 5 array?  if so is the array intact?

2) does the drive have at least 15% free space?  if not you must manually determine how to accomplish (AT LEAST 10%) 15% free space.

3) does the drive pass a chkdsk on bootup

4) move to NTFS

5) defragment

acesover2000,

I am working on a local work station and I want to perform disk clean up on my own local computer.

I have done defragment. I have 27% free space. The file system is NTFS.

Your other 2 request I am not sure. Please provide further instruction.

Thanks.

See the following Microsoft link,

This happens more than you would think, there is an issue with the compress old files option.
