    Symlink Creator

    Program to create symlinks. Provides the CMD command as well.

    Just a small application I made to simplify the process of creating symbolic and hard links in Windows 7 and Windows 8 (likely Vista too). It is a GUI for the MKLINK command in Windows, which makes creating the links much easier. The program requires administrator permissions due to use of the command prompt, so you should run it as an administrator if you experience any problems. Note: It is not possible to create a hard link from a network share. You must use a symbolic link instead. Warning: If you incorrectly specify the destination path, such as having the destination and source paths backwards, it will delete the file/folder you are presumably trying to create a symlink from. You will be presented with a confirmation prompt that shows you which folder will be replaced/deleted. It is always a good idea to test this app on empty files or folders.

Files, links and folders are organized in several levels as dropdown menus. Various options like appearance, hotkey, autostart and behavior can be adjusted. It is written in C# and using .NET 7.

After starting the application the first time you have to choose the root directory. In this directory you should put shortcuts, files and folders (App, Game, Script, URL, Network), which you are often using and especially when you can not find them over the windows start menu search. You can also consider to put there all files from your desktop. If you have ideas, questions or a problem you can contact the developer Markus Hofknecht via GitHub or email.
