What is the difference between -vmdk and -flat.vmdk
One is a pointer to the other - The reason for having 2 is something to do with management of thin disks (I think)
almost all of the different virtual disk types use a separate descriptor-file because it is easier to handle than embedded descriptor-files.

the .vmdk file is a stub file or descriptive file as was mentioned.
the -flat file is the actial virtual disk file

The .vmdk file (also called the descriptor) is a text file that contains configuration information about a VM’s virtual hard drive. The *-flat.vmdk file is the virtual equivalent of a physical hard drive, this is where raw data is written to. You won’t find this file listed in Directory Browser. It is instead combined with the descriptor file and presented as a single file.
VMDK files. All virtual disks are made up of two files, a large data file equal to the size of the virtual disk and a small text disk descriptor file, which describes the size and geometry of the virtual disk file. The descriptor file also contains a pointer to the large data file as well as information on the virtual disks drive sectors, heads, cylinders and disk adapter type. In most cases these files will have the same name as the data file that it is associated with (i.e., myvm_1.vmdk and myvm_1-flat.vmdk). You can match the descriptor file to the data file by checking the Extent Description field in this file to see which -flat, -rdm or -delta file is linked to it.
node7 has two disks listed in config, in a datastore default thin provision
Do I have wasted space/orphan files here?
You should open an new fresh thread with your question. Please provide the output of
grep vmdk *.vmx
It looks like that you create a snap 2 month ago and have not deleted it since.
In case you will lose or damage your flat. vmdk you can lost your data. Only backup will be able to assist.
that was it. thank you for the reply, and sorry for intruding in this thread.
