However, they have the effect of changing an otherwise hierarchic filesystem from a tree into a directed graph, which can have consequences for such simple operations as determining the current directory of a process. Symbolic links operate transparently for many operations: programs that read or write to files named by a symbolic link will behave as if operating directly on the target file. Hard links always refer to an existing file, whereas symbolic links may contain an arbitrary path that does not point to anything. Hard links do not link paths on different volumes or file systems, whereas symbolic links may point to any file or directory irrespective of the volumes on which the link and target reside. Symbolic links are different from hard links. Symbolic links pointing to moved or non-existing targets are sometimes called broken, orphaned, dead, or dangling. If a symbolic link points to a target, and sometime later that target is moved, renamed or deleted, the symbolic link is not automatically updated or deleted, but continues to exist and still points to the old target, now a non-existing location or file. If a symbolic link is deleted, its target remains unaffected. The symbolic link is a second file that exists independently of its target. This other file or directory is called the "target". 2 POSIX and Unix-like operating systemsĪ symbolic link contains a text string that is automatically interpreted and followed by the operating system as a path to another file or directory.Here, in this command prompt screenshot, you can see that I created a symbolic link of my Music folder to my desktop. Note that the first path was to the symbolic folder I wanted to create, while the second path was to the real folder. Mklink /J C:\Users\Matthew\Desktop\Dropbox C:\Users\Matthew\Documents\Dropbox For example, if I wanted a folder in my Dropbox folder to appear like it was also stored in my desktop, I would enter the following: So, once you’ve chosen the correct prefix, you need to enter the path you want for the symbolic link, and the path to the original file or folder. /J – creates a hard link to a directory or folder.This is the default option, and mklink will use it if you do not enter a prefix. /D – creates a soft symbolic link, which is similar to a standard folder or file shortcut in Windows.Mklink can create several types of links, including the following: Mklink / prefix link_path file/folder_pathįirst, choose the correct prefix. To create a symbolic link, we need to enter the following in command prompt: Run and install the Visual Studio 2005 Redistributable installer first. Download the correct version (32 bit or 64 bit) for your computer. You need to download both Visual Studio 2005 redistributable, which contains the necessary prerequisites, and Link Shell Extension itself ( links below). This can create a loop, which can cause millions of problems you don’t want to deal with.Ĭreate Symlinks in Any Edition of Windows in ExplorerĬreating symlinks is usually difficult, but thanks to the free Link Shell Extension, you can create symbolic links in all modern version of Windows pain-free. For instance, don’t create a symbolic link to a file that’s contained in a symbolic linked folder. Follow the correct instructions below for your operating system to create the symbolic link.Ĭaution: Make sure to never create a symbolic link inside of a symbolic link.Move the file or folder to the new desired location.Close any programs that may be accessing that file or folder.If you want to move files to a different drive or folder and then symbolically link them, follow these steps: Keep important files accessible from multiple locations.Store your Music/Pictures/Videos on a second hard drive, but make them show up in your standard Music/Pictures/Videos folders so they’ll be detected my your media programs (Windows 7 Libraries can also be good for this).Move the settings folder for any program from its original location.Sync any folder with Dropbox – say, sync your Pidgin Profile Across Computers.There are many things we use symbolic links for, so here’s some of the top uses we can think of: However, a hard link makes it appear as though the file or folder actually exists at the location of the symbolic link, and your applications won’t know any different. When you open a soft link, you will be redirected to the folder where the files are stored. Soft symbolic links work essentially the same as a standard shortcut. There are two types of symbolic links: hard and soft. You can create symbolic links to individual files or folders, and then these will appear like they are stored in the folder with the symbolic link even though the symbolic link only points to their real location. Symbolic links, otherwise known as symlinks, are basically advanced shortcuts.
