Windows – xcopy /exclude issue


I am trying to run xcopy that copies files excluding .obj, etc.
What I am seeing is that Microsoft.Practices.ObjectBuilder.dll is not copied when my excludes.txt file contains .obj as an extension. When .obj is removed, I Microsoft.Practices.ObjectBuilder.dll is copied correctly. This does not happen to other dlls though.

Does anyone have any idea why this would happen?



Best Solution

I guess because the substring .obj is found in the name Microsoft.Practices**.Obj**ectBuilder.dll and since windows is not case sensitive, it will exclude it.
