Introduction

The other day at work I was cleaning up a project and got frustrated because i wanted to remove all images that are no longer referenced inside CSHTML, CSS, and LESS files ..but couldn't find any soft or plugin that would help me, so I got stuck with selecting each image name one by one and then searching through the entire project for each file to see if I got a match or not ..Grrrrr!

So I decided to whip up a little soft to help automate just that.  

Works as a Standalone Application, from the Windows Explorer context menu, from the Command Line, or as a Visual Studio extension. Thank's to the command line it can easily be integrated with your favorite development IDE too. 

 

Flat View

Tree View

File/Folder Exclusions

Thumbnail Preview

 

Parsing Dialog

 

 

 Windows Explorer (context menu)  

 

 

Visual Studio (context menu)

 

 

The process was really easy, so unless i missed something, i'm surprised i couldn't find some program on the web that already did just that.

Anyways here's how it works: 

  1. enter a regexp that matches files you want to match
  2. choose if you want to match if they are used or not used
  3. choose what filetypes you want to search within to see if they have references in there
  4. select your starting directory 
  5. ......processing 

The simple logic behind it:

  1. load all file names from base directory & sub-directories
  2. extract all file names that match what we are looking for
  3. extract all file names that match which files we will be searching in
  4. iterate over each of the files we are searching in
  5. open each file and iterate over the content
  6. check if the content contains a match and add to a match list if so
  7. do a diff between matched and all

That's all, and it's pretty fast too. And since it uses standard regexp as input, you can match pretty much anything in any type of file. 

Features: 

  • Can be launched via the command line. Like this it's easy to integrate with Visual Studio, Eclipse, Zend Studio, NetBeans, IntelliJ IDEA, etc.  
  • Double clicking a path in the visible list will open the directory the file is contained in
  • Once file processing is done you can toggle the visible list between used/unused lists
  • Select items in list and export the paths to a text file for later investigation 
  • Regexp criteria is saved after successful search and restored on application launch
  • Selecting one or more paths in the visible list and clicking delete, will prompt you if you really want to delete the file(s)
  •   

Requires .NET 4 for the Application or .NET 4.5 / Visual Studio 2012 (and up) for the Plug-in

Oh, I see my suggestion is already in there! Thank you - the current implementation is more than good enough for me! Smile | :)
