VMware Server 當掉後重新啟動 Guest OS 時，出現
cannot open the disk '*.vmdk' or one of the snapshot disk is depends on.
Reason: Failed to lock the file.
解決方法一:
進到 VMware 的 Guest OS 資料夾，將所有的 *.lck 資料夾或檔案刪除
可以使用everything.exe 搜索虚拟机对应的文件夹下的所有*.lck文件，然后全部删除。
VMWare Workstation VM not starting because of locked portion of file
The process cannot access the file because another process has locked a portion of the file
Cannot open the disk 'C:\Users\t825665\VM's\VPC\Windows 10 x64.vmdk' or one of the snapshot disks it depends on.
Module 'Disk' power on failed.
Failed to start the virtual machine.
I just found the solution for this issue. I created a backup and moved the 'lck' files from my VM's directory (*.lck), removing them from the VM's directory. Then just restarted the virtual machine
The above solution worked perfectly
