how to list files in a directory, to then manipulate each file.

I want to automaticaly manipulate each file in a directory. First thing is to be able ( and I have searched long nights unsuccessfully) to list files in a directory, then treat one at a time.
I'm writting a DOS console application, C++, win2000.

you'll find the dir.h header has a lot of file/dir manip stuff

use findnextfile or something like that, getcwd, chdir etc functions to use files and dirs.

hope this gets you started.

HEY! Thanks........just the name of it looks promissing (dir.h)
I'm sure it's not in any of my books. I'll have to wait till I get to work to check it out... in any case...thank you very much. :p

Ok... I bumped into the same challenge recently... First of all, you'll need to find a way to get the file-name of each file ( sometimes directories pretend to be files too). To do this, you can use functions such as 'findfirst()' and 'findnext()' or any other funtion. Then you'll have to use a buffer to store the filename of each individual file. This is though. I'm using linked lists now, but it sometimes gives me problems when I bump into more than 100 or so files in one dir... so you c... If you do come out with anything better than me, please post a reply, coz i'm really interested in finding out...:)

Thanks

As a matter of fact, directories are files. They are just treated differently when encountered. DOS implements numerous disk I/O functions like findnext() and findfirst() via int 21h. Check out RBIL to view these interrupts or you can try to get your hands on a DOS tech ref. The disk I/O functions are far too numerous for me to list them here.

I know BASIC has a statement which will print (to the screen) a directory of a folder (just like typing DIR), but I have never been able to either manipulate so you could access that data as variables in a program, or found the C/ASM equivalent.
