When a bitmap resource is modified and is moved to a different folder in a Microsoft Visual C# .NET solution without saving the bitmap first, the changes that are made to the bitmap resource are lost. If the solution is closed and then reopened, two bitmap resources are present. One bitmap resource is in the original location and the other bitmap resource is in the folder where the bitmap was moved.
This problem occurs because Microsoft Visual Studio .NET performs a copy operation instead of performing a move operation to move the bitmap to the new location. This problem only occurs when changes are made to the bitmap and it is moved before the changes are saved.

To work around this problem, save changes to a bitmap resource before you move it.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.
Steps to reproduce the problem
In Visual Studio .NET, create a new Microsoft Visual C# .NET Windows Application.
In Solution Explorer, right-click the project, point to Add, and then click New Folder.
Right-click the project, point to Add, and then click New Item.
In the Add New Item dialog box, click Bitmap File.
Edit the bitmap image.
Move the bitmap to the folder that was created in step 2.
Open the bitmap resource. Notice that the changes that were made in step 5 are not saved..
Close and then reopen the solution. Two bitmap resources will appear. One bitmap will be located under the folder that you created in step 2 and the other bitmap will be located under the project root.
The problem can be prevented by saving the bitmap resource after step 5 and before step 6.
