Question

I would like to check how many files are there in the specified directory. For instance I would have a directory next to my .exe called resources and I would like to check how many of .txt files are located in it.

How this can be done in C++ in Windows?

Answer 1

This depends on the operating system. On Windows, you would use FindFirstFile and FindNextFile to enumerate the directory contents, using an appropriate filter such as "*.txt". Don’t foget to call FindClose when you’re done.

On Unix-based operating systems, you would use opendir(3) and readdir(3) to enumerate the directory contents. You’ll have to filter the file names yourself. Don’t forget to call closedir(3) when you’re done.
