Parsing Windows shortcut files

As a yard, the work will often use a variety of tools, in order to improve the efficiency of the brick, I have been using executor as a quick start tool, want to open what program directly snapped a few keyboards, forcing lattice full, and then get to a new skill: A folder to store the shortcuts of common programs, Then add the path of this folder to the path system environment variable, you can use "Win + R" To open the common program. Disadvantage is inconvenient management, many programs have been deleted, but the shortcut is still in, causing a lot of invalid shortcuts, so you want to write a program to automatically delete invalid shortcuts, but did not find a ready to parse the shortcut file of the library, it seems to be able to build their own wheels.

Detailed documentation for this file format is available on MSDN. A lot of information in the file, but most of them do not use, do not want to spend time to toss, only resolved three: the target path, whether it is a directory and shortcut keys.

This is basically the class, relatively simple, not a few lines of code:
