'I can't see the folders I created in my project

I have been working on a project in C# in Microsoft Visual Studio 2012. Since I have a lot of C# files I decided to put them in a few folders based on their type. For example an interfaces folder and an enumerations folder.

Now when I open my project I can't see any of my folders and all of my C# files are not in folders. I can't open the files because it says that the directory has changed or has been deleted. I am adding a photo so you will be able to see what happened to me.

You should've created the folders and moved the files inside the VS Solution explorer, then everything is tracked automatically.

The easiest way to fix this is to enable "Show all files" at the top of the solution explorer, refresh the view to make sure you can see everything

Then right-click the slightly grayed out folders and choose "Include in project"

Once that's done, delete the "Broken" old files.

Follow the steps to add the files back to the solution

  1. From the Project menu toggle on "Show All Files"
  2. Now you should see the files/folders in Solution Explorer.
  3. Select those you want to include
  4. right click and choose "Include in Project"
  5. after include all files delete the broken file links

Solution 3:[3]

Sometimes you have to click "Refresh" in the solution explorer first. Then you will be able to see hidden files, when clicking "Show all files" and you will be able to "include them in project".

Solution 4:[4]

sometimes Visual Studio file tree lacks your latest update to solution explorer so, the solution is to just right click on your solution and select "Sync Namespaces"
