By default, all VM-related files are in a single folder with the original VM name (or the VM name after a VM storage migration). You can place the different files in different datastores based on your needs. The following files are part of the virtual machine:

• VMDK files: Having virtual disks in different datastores allows you to choose the proper type of disks with the proper performance and service level. You can choose a new location when you add a new virtual disk or choose different locations for each VMDK when you apply a storage migration.
• Swap file: Migrating VM swap (.vswp) files to a different datastore is possible and described in KB 2003956: Migrating virtual machine swap (.vswp) files from one datastore to another (https://kb.vmware.com/kb/2003956). You can also use an SSD datastore for this purpose, but usually, the need for a different position occurs when storage array replication is used, and you need to avoid swap file replication.
• Log files: By default, ESXi/ESX hosts store VMs specific logging in the same directory as the VM configuration files. VM logs can be reconfigured to archive at different intervals, with different names, in different volumes, or when the log reaches a specific size. For more information, see KB 1007805: Locating virtual machine log files on an ESXi/ESX host (https://kb.vmware.com/kb/1007805).
• Snapshot files: All files with snapshots are created in the VM working directory, which, by default, is the same directory as that of the VM. The working directory can be changed with KB 1002929: Creating snapshots in a different location than default virtual machine directory for VMware ESXi and VMware ESX (https://kb.vmware.com/kb/1002929).
