I have two datastores and each one has contentlib-xxxxxxxx-xxxx-xxxxxxxxxxxx folders but I don't have a content library set up (and from what I've read that seems to be the purpose of these folders) - I'm guessing that they are left over from a previous vCenter installation which no longer exists.
One of the contentlib folders has two subfolders with xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx names. These folders each contain a vmdk and an ovf file.
The other datastore contentlib folder has a single subfolder with two vmdk's, an iso and an ovf file.
All of the files in both contentlib folders have the same time stamp from over two rears ago,
Is there anything likely to be relying on or running from any of these files? I need to create a bit of free space and these look like good targets to be deleted.
