How to Reduce disk space consumption when using VMware Workstation 1. if not necessary, "shutdown" rather than "suspended" is mainly based on the following two reasons: (1) when a VM is running, a file with the suffix vmem will be generated (the file size is the same as the configured VM memory size). The file is automatically cleared only after the VM is shut down. After the VM is suspended, the file still exists. (2) After the VM is suspended, A vmss file with the same name as the vmem file will be generated in the directory where the VM is located. 2. shut down the VM before creating a snapshot. If a snapshot is created during running, an additional vmem file is generated to record the memory status of the VM. The file size is equal to the memory capacity of the VM. This additional overhead is necessary in most cases. 3. creating a VM snapshot file at a very important location takes up a certain amount of disk space (creating a snapshot after Shutdown only allows the snapshot file to be as small as possible, not equal to not occupying space ), therefore, snapshots cannot be flooded.

Two data values indicate the size before and after the virtual machine tool is installed.
