Convert UNC Path to its corresponding mapped Drive path?

On my test system (Windows 10 x64), the UNC PATH \\Mac\Home\Documents is mapped to Y:\Documents. Is there a Delphi function to generally convert a UNC Path to its corresponding mapped Drive path (if it has one)?

function ConvertUNCPathToDrivePath(const AUncPath: string): string;

This would convert \\Mac\Home\Documents to Y:\Documents.

Solution

  • AFAIK, there are no functions to convert a UNC path to a mapped-drive path.

    However, there are Win32 API functions, such as WNetGetConnection() and WNetGetUniversalName(), which can be used to convert a mapped-drive path to its UNC path.

    You can enumerate the local drive letters and see if any of them convert to the UNC you are interested in.
