Can I delete a .vmfsBalloon file ?

I started an unmap command, vmkfstools -y 65  and all was good. I went away for 60 min and when I returned, I had lost my vpn connection and my putty connection ,and have a 143 GB .vmfsBalloon file in the root of the datastore

Can I delete this file ?

Do I need to check for a stuck process first ?

Thanks !

Tommy

This command creates temporary hidden files at the top level of the datastore with names using the .vmfsBalloon* pattern (for example, .vmfsBalloonGdwBBv). These files can be as large as the aggregate size of blocks being reclaimed. If the reclaim operation or storage access is interrupted, these temporary files might not be automatically deleted and you must delete them manually to create free space on the datastore. For more information, see How to reclaim VMFS deleted blocks on thin-provisioned LUNs (2014849) | VMware KB and Using the esxcli storage vmfs unmap command to reclaim VMFS deleted blocks on thin-provisioned LUNs ...
