You may have encountered the "File in use" errors when deleting files/folders, especially when clearing out the Temp folder. To successfully delete the temporary files which are in use, you need to determine the process name which has locked the file, and then close the corresponding application first. In Windows 7, the File In Use dialog has improved, as it displays the name of the process which has locked the file.
Here is how the File In Use dialogs appear in various Windows Operating Systems
Windows XP
Windows Vista
Windows 7

Great post! These are necessary things to keep in mind, it’s often easy to forget regarding the simple things once you get consumed by a project.
Hi,
looks like Windows 7 does it itself when you open file with the WIN32 API.

I don’t understand why IE (in Vista) does not implement the interface but IE in W7 does? Those two examples (screenshots 2 & 3) involve IE only. To better explain this, see this screenshot:

In both the occasions, the executable file (clsidviewer.exe) is the same. I’m the author of that proggie and I haven’t implemented the IFileInUse interface.
Windows Explorer calls it too in Vista, but the application that opens the file must implement the inferface. Here is an example of an opened Word File which I try to delete under Vista Sp1.

@Andre: Thanks! Does that mean that Windows Explorer in Vista does not call/use this function, but Windows 7 Explorer does?
Hi,
the Information about the application is also displayed under Vista if the Application implements the IFileIsInUse Inferface ;) This is not a new feature from Windows 7
