title: How to overwrite an asset (PNG image) file in TFS 2010
body: <p>first question I've asked so please go easy, also an absolute newbie with TFS (within Visual Studio 2010 in this context).</p>
  
  <p>I have spent some time seeking an answer to this question both via SA and further afield, pretty shocked at how unintuitive this process seems to be given how fundamental it is. Slightly embarrassing.</p>
  
  <p>In short: Three assets are shown in Source Control (three icons). I've now created three replacement icons via GIMP that I wish to use in the project, but I can't work out how to overwrite the old ones and put my new ones up.</p>
  
  <p>I have read that I should 'check out' the existing three, which I have done, but I still can't then right-click on their containing folder in TFS and choose 'Add Items to Folder' - it complains that files with these names already exist with no option to overwrite.</p>
  
  <p>edit - I don't have the ability to install any add-ons or other software on my machine :(</p>
