Windows style path conversion macro X:\path\tofile => //SERVER/res/path/tofile

Please advise if there is any suitable macro/script I can bind to the hotkey to convert file path from windows style x:\path\tofile\name.ext to open directly from MAC?

The problem is that local intranet have all links posted in windows pre-mapped drive names and I need to open them in my MAC.

Thank you in advance.
