This is one that comes up from time to time, and I am always re-inventing the wheel trying to come up with a standard (usually to just find out that it conflicts with the ‘standard’ I came up with six months before).
So, to provide myself with a reference, I am creating this entry: based on the names suggested on this site.
Assume the current directory is C:\users\Joe\For Work\
|Path and File||Part name|
|C:\users\Joe\For Work\Widget\foo.src||absolute path or full path, or path|
|C:\users\Joe\For Work\Widget\foo.src||absolute directory or current directory|
|C:\users\Joe\For Work\Widget\foo.src||relative path|
|C:\users\Joe\For Work\Widget\foo.src||file name or base name|
|C:\users\Joe\For Work\Widget\foo.src||file root|
|C:\users\Joe\For Work\Widget\foo.src||file extension (with or without the dot)|
