I have a Parallels Desktop VM installed with Windows XP. One day I recognized that the disk usage increased dramatically. I found out that there are multiple files like <diskname>.0.{GUID}.hds :
-rw-r--r-- 1 admin staff 2,1K 14 Nov 00:44 DiskDescriptor.xml
-rw-r--r-- 1 admin staff 2,1K 14 Nov 00:44 DiskDescriptor.xml.Backup

Which action created new .hds files, are thy related to snapshots ?
Are really all of them used or is only the newest one relevant and others can be deleted ?
