Several APIs that I have worked with deal with the file system in some form or fashion. However there does not seem to be any sense of unity with respect to property and method names when it comes to the display form returned or processed.
The two most common forms of file representations that I have encountered are the file name and the full path of the file. It is usually unclear from the property or method name, which it is returning. A lot of places where they return the full path of the file have the property name such as FileName. For me that is counter intuitive and there should be an easy way to tell without having to look up the API every time.
The best representation that I have come across is the following
FileName – Returns just the name of the file
FilePath – Returns the full path of the file including the file name
