Some thing every VMWare admin will end up doing at some point is orpahen file hunting. That fun task of hunting down unused VM disks hopefully before your datastore is out of space.<\/p>\n\n\n\n
Working for a cloud provider, wasted space is always a problem and RVTools has been my tool of choice for years. RVTools does not give me file size or last modification time. Two very important bits of information in the “can I delete this?” decision. But RVTools is quick, very quick (and free). <\/p>\n\n\n\n
Here is a handy bit of Powershell that is not quite as quick as RVTools but is not that much slower, and will give me Last modified date and the file size.<\/p>\n\n\n

Orphs.cav will list every file on your datastore that is not part of a VM or template.<\/p>\n\n\n\n
Orph-disks.csv will list only the VMDKs <\/p>\n\n\n\n
Note: when scanning the datastore at the file level the result can not distinguish between a file and a directory. So in the full report there will be odd results more then once directory level deep.<\/p>\n\n\n\n
The is a lot of system stuff saved on DataStores. Cluster HA, Host scratch etc. all this will show up in the full report. <\/p>\n\n\n\n
Disks are what you are looking for, Use the disk report.<\/p>\n","protected":false},"excerpt":{"rendered":"
