Rename directory source code files are in

deleyd used Ask the Experts™
I would like to rename sub folder MyTestProject 20011-09-01 on the right to MyTestProject (see image). How can I do this so Visual Studio 2010 still knows where all my project files are?

If you just want to rename the solution/project, select the solution/project in solution explorer, then press F2 or change Name in properties window.
If you wan't to rename the physical folder. Close Visual Studio, rename the folder in Explorer.
If you changed the solutionname, just open the solutionfile in the new location.
If you changed the projectname, project will be listed as unavailable in solution explorer. Then you have to edit the File path property in properties window.

The *.sln files and the associated project files (*.vbproj, *.csproj, *.vcproj, etc) are all just text-based XML files.

You can easily poke around them using NotePad (or any text editor) and tweak the directory names to match what you've changed them to

Rename the directory, open the .sln and change the path to the project.

If you have standard projects configurations, you do not need to tweak the *.*proj files, since they contain relative paths to the files in the project.

In future projects, when you create the project, do not check the checkbox "Create Directory for Solution". The .sln will then be in the same directory as the *.*proj and all the paths will be relative, so you will be able to change the directory name at any time.

This the way I work with my training material. I can move it in any classroom or in the field when I give private training, and my sample applications can be installed in any directory.
