Free space consolidation (no defragmentation needed)

Hello experts, I'm working with Virtual PC using dynamic expanding disks.

I need to compact some virtual disks that have a lot of free space but some data sectors are near the end of the disk, disallowing me to do it.

I've tried several defragmenters that claim they "consolidate free space" but they really don't do it the way I need.

Diskeeper is near to really consolidate space with its boot time defrag option; but for some reason, it lets a small chunk of data near the end.

This question is for ask you if you know about an application that move all used sectors to the start of the disk (or partition); I don't care if files remains fragmented, only the space at the end is what I need.

Thank you very much.


Fidencio Monroy.

I've heard of somebody who mounted the VHD files under a Virtual Vista, and used Vista's own defrag utility to compact the disks.   This apparently does a fairly good job of consolidating the free space

The VHD files themselves where from an assortment of OSs.   I don't remember if the story also included the use of the "Pre Compactor" utility.

I personnally have never tried it (so I'd recommend you make a backup).

If it works, please do let us know, so we can have this answer for the next time somebody asks

I still have no a vista's license to do that test, this do the work:
Use PerfectDisk 8 to do an offline defrag of system and page files.
Then use the precompactor utility as u suggested.

I read that swap file space can be compacted too, but not with this method.

You can get rid of swap file to allow maximum compression using this way. It's OK for me, because I need those vhds as templates or fresh installations.

Thanks a lot.
