Converting between a Mac file path to a Windows file path

I am working in an office that is dominated by PCs, but we are moving select designers to a Mac platform (testing). The biggest issue I have come across is sharing file paths to shared drives, and the formatting differences. Please tell me there is a simple answer.

I am looking for a way for our designers to write an email and link to a file on the drive, but convert the file path to windows formatting. And visa versa (getting an email with a windows file path, and converting it to a mac file path).

File path examples:
Mac formatting: /Volumes/Share/Main Folder/Folder1/Folder2/FinalFolder
Windows formatting: S:\Main Folder\Folder1\Folder2\FinalFolder

We have multiple shared drives, so it could be multiple letters, not just "S".

Stay with the Windows path style and install WinShortcutter 3.5 (Freeware) on the Mac side. Since you are using mapped drives on the Windows PCs: e.g. S:\Main Folder\Folder1... you have to configure the proper mappings e.g \\Share\pictures\ -> S:\ in the app on every Mac though.
