I think we little misunderstood it. Do you want full path of the file (including it's base directory name i.e. absolute path of the file) or only the file name?
If you need full path of the file, simply use the full path of base directory in find cmd, as:
~$ find /full/path/of/base_directory <expressions> <options>
On the other hand, if you need file names only i.e. file1, file2... etc. then you can give a try to (I didn't tested it):
~$ find /full/path/of/base_directory <expressions> <options> | basename -
