A single file can have more than one absolute path, but only one canonical.
That is, if two files have different canonical paths, they are different files. The same is *not* true for absolute paths.
For example, both "C:\foo.txt" and "C:\.\foo.txt" are absolute paths that refer to the same file.

As far as I can tell, comparing canonical paths is the only way to know wether two File objects reference the same physical file. I'd assume that calculating the canonical path is potentially slower and might be inapropriate to confront the user with, though.

Agree with Ilja. Thats why we have to use canonical path to identify symbolic links in Unix based systems.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
