Too many vmware files on documents

I have installed sierra on vmware workstation pro. When I looked up my vmware files on my documents, I recognized that the folder includes lots of vmdk files. Can I delete some of them ?

From the Virtual Machine Files article in VMware Workstation Pro Documentation:

vname-s###.vmdk

If you specified that the files can increase, filenames include an s in the file number, for example, Windows 7-s001.vmdk.

If you specified that the virtual disk is divided into 2GB sections, the number of files depends on the size of the virtual disk. As data is added to a virtual disk, the files increase to a maximum of 2GB each.

In other words:

Your virtual hard drive(s) are split into multiple discrete files on your hypervisor file system.

Don't delete them.

VMware will manage its own files according to its own rules and taking into account any settings you may have set. Leave them alone.
