It sounds like you are just calling toString() on the selection. Maybe
check if the first element is an IResource, and then you can do
getPath() which has a few additional to*String() methods.
Hope that helps.

Un-checked casting is dangerous because it assumes the selection is an
IFile. Better would be to use the Adatper framework. For example, a call
like this:
org.eclipse.core.runtime.Platform.getAdapterManager().getAda pter(mySelection,
IFile.class)
The selection can be a lot of different things that are not IFile
instances but that can be adapted to IFile. Using code like above, if
the selection is anything that can be adapted to an IFile, you're code
will work even if it is not actually an IFile. Using this technique will
make your code more robust and allow it to integrate with other plug-ins
or views that don't use IFile as the basis for defining the selection.
You can learn about adapters here:

Hope this helps,
