system() too big?

I'm trying to issue a system call from my program. However, when I run the program, I get the message "Program too big to fit in memory"

Does anyone have any idea why this is, and how I might fix this? Specifically, I'm trying to do this:

system (Cmd);

where Cmd is a xcopy command string. I checked the command string and it is what it's supposed to be. If I type the exact same command at the command prompt, it works fine and the folder is copied correctly. But when I'm running it from my program, it says program too big and the very next line it says "File not found - (name of folder I'm trying to copy)

Thanks.

Maybe your program takes up so much memory that xcopy doesn't have any?

Do you have any really big arrays?

I have some string buffers that are maximum of 600 characters. All of them together shouldn't exceed 5k bytes, I'd say. So how is it possible to run out of memory?

Maybe post some code so we can have a look?

Thanks for your help. Just found out I'm not supposed to use the system() call. So now I have a new problem of trying to copy files and folders manually. Still figuring out how to do that.

Um... do it yourself? :)
Write a recursive function which traverses the directories, copying files and creating folders as you go.

Google: opendir, readdir, mkdir, fopen, fread, fwrite. All are part of Standard/POSIX C.

There's an FAQ entry with a sample program that parses directories.
