I recently had to create a symbolic link to overcome a bug in OpenSSH whereby OPENSSH won’t work with the path C:\Program Files\PowerShell\6\pwsh.exe because it has a space.
The answer is to create a symbolic link which is a file that contains a reference to another file (or directory):
New-Item -ItemType SymbolicLink -Path C:\pwsh -Target ‘C:\Program Files\PowerShell\6’
C:\pwsh is the symbolic link and the Target parameter has the original path. You can now use C:\pwsh in place of C:\Program Files\PowerShell\6
New-Item can also create a Hardlink or a Junction.
HardLink is a directory entry that associates a name with a file on disk
Junction is an NTFS artefact that is a pointer to a directory on the local volume
