Method GetMappedDriveFilePath

PathCopyCopy/plugins/src/UNCPathPlugin.cpp:117–138

Checks if the given file resides on a mapped network drive. If it does, returns its corresponding network path. Ex: N:\Data\File.txt -> \\server\share\Data\File.txt @param p_rFilePath Local file path. Upon exit, will contain network path. @returns true if the file was on a mapped network drive and we fetched its network path.

        // @returns true if the file was on a mapped network drive and we fetched its network path.
        //

            // if file is on a mapped drive.
