Cannot Generate .tar File

Question

How do I make a .tar from current directory tree in Win10? Trying tar -c Archive.tar * and getting tar: Failed to open '\\.\tape0'.

C:\>tar -h

Answer 1

-f <filename>  Location of archive (default \\.\tape0)

You missed -f so tar used the default location (treating Archive.tar as a file to be archived). Your command should be like

tar -cf Archive.tar *

although I don't know PowerShell's rules of usage of *. You may try to pass -- just before * to make tar stop parsing options, I hope your tar understands this. This is in case * returns something which initial part looks like options for tar.
