When attempting to copy-paste your Virtual machine's .pvm file to some other location (to/from the External Hard disk or another folder on the same Hard Drive) the error message shows up:
The Finder can’t complete the operation because some data in “***.pvm” can’t be read or written. (Error code -36)
The issue may occur if incorrect permissions were set to the .pvm bundle or some of the files inside it. Another possible cause for the issue is bad blocks on the hard drive your .pvm is located on.
We would recommend checking the macOS system log for I/O errors while attempting to copy the .pvm.
For more information, please contact Apple Support for help.
We would strongly recommend you contacting Apple Support to recover your data.
