    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.

    SystemTrayMenu

    SystemTrayMenu

    SystemTrayMenu is an open source 'Desktop Toolbar' or 'Start Menu' alternative. It offers a clear, personalized menu which can be controlled via keyboard, mouse or touchscreen. 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. SystemTrayMenu is portable, so it does not need to be installed. After downloading the zip file, unzip the folder, then start SystemTrayMenu.exe. 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.

    A simple utility for tweaking attributes of directories's contents and

    Computer virus is a major disorder, there is nothing to discuss. But fortunately, a good antivirus can detect and remove these threats. Still, some viruses modify folders on your computer before you remove them, hidden folders, removing shortcuts, among others.

The Attribute Tweaker offers you the option of finding hidden folders in your computer with ease. All you need to do is open the program, choose the directory where to find the file that was hidden or moved and select the desired option - find icons or hidden folders. In the Attribute interface Tweaker, click 'Browse' and select the folder on your computer where you want to find hidden files or folders. Then choose the options available in the program to enable hidden files set to read-only file system. Choose the desired option and click 'Apply'.
