( but i don't know how to open a directory when the dir name is
given as a string

ie i would call
myapp.exe F:\mycode\mypngfiles\

any advise ,pointers wd be most appreciated
thank you

Take a look at the functionality included in <dirent.h>. This header files declares functions to browse a directory and lists its content and is, if I recall correctly, also mentioned in the K&R book. However, I can't say for sure this functionality is available on MS Windows using the MS Visual C compiler. Maybe you'll need to find some WINAPI functions that mimic <dirent.h> behavior.

If you have the list of file, you only need to do a string comparison on the file extension. To be a 100% safe you should take a look at the MIME settings of the file because on Unix for example file extensions are not mandatory. This is however outside the scope of this discussion group.
