Path Length Checker is a stand-alone app that allows you to specify a root (i.e. starting) directory, and it gives you back a list of all paths (i.e. files and directories) in that root directory and their lengths. It includes features such as pattern matching and min/max length constraints, as well as the ability to specify a string that should replace the root directory in the results brought back, allowing you to quickly see path lengths if you were to move the files/folders to another location.

Download it from the Releases page.

To run the Path Length Checker using the GUI, run the PathLengthCheckerGUI.exe.

Once the app is open, simply provide the Starting Directory you want it to search and press the large Get Path Lengths... button.

You can also drag-and-drop a directory from File Explorer onto the PathLengthCheckerGUI.exe file to have it open up the application and search the directory automatically.

The PathLengthChecker.exe is the command-line alternative to the GUI. Simply run it without any parameters to see what parameters you can pass to it.

PathLengthCheckerGUI.exe also supports the same command-line parameter syntax. Additionally, specifying the target directory alone as the only argument is supported and will begin a search on the supplied path using defaults. This is useful for launching the GUI application from other programs, such as a Windows Explorer context menu action.

The Search Pattern parameter is used to match against specific file/directory names. It is not case sensitive, and it supports the wildcards (*) for zero or more characters, and (?) for zero or one character.

Examples:

• test.txt matches only files named "test.txt".
• test matches any directory named "test", as well as any files named "test" that do not have an extension.
• test* matches any file or directory whose name begins with "test".
• *txt matches any files with a ".txt" extension, as well as any directory whose name ends in "txt".
• *test* matches any file or directory that contains "test" anywhere in the name or extension.

For more information on the search pattern syntax, see the official Microsoft documentation.
