In Windows 7, for example, when using vmware workstation to access Linux (the disk XX. vmdk cannot be opened or the disk on which a snapshot is dependent: the file cannot be locked)

Cause:
Virtual Disk (. vmdk) has a disk protection mechanism to prevent multiple virtual machines from simultaneously accessing the same virtual disk (. vmdk) brings about data loss and performance reduction risks. Each time a virtual machine is started, the virtual opportunity to use the extension is. the LCK (Disk lock) file on the Virtual Disk (. vmdk. When the VM is disabled, the. LCK (Disk lock) file is automatically deleted. However, you may not be able to delete the. LCK (Disk lock) file on your system before shutting down the VM abnormally. The above error occurs the next time you start the VM.
Solution: Delete the virtual machine configuration file and all files and folders ending with. LCK in the Virtual Disk folder.
