Lightweight, portable and easy to integrate C directory and file reader. TinyDir wraps dirent for POSIX and FindFirstFile for Windows.

Windows unicode is supported by defining UNICODE and _UNICODE before including tinydir.h.

There are two methods. Error checking omitted:

tinydir_dir dir;
tinydir_open(&dir, "/path/to/dir");
while (dir.has_next)
{
	tinydir_file file;
	tinydir_readfile(&dir, &file);
	printf("%s", file.name);
	if (file.is_dir)
	{
		printf("/");
	}
	printf("\n");
	tinydir_next(&dir);
}
tinydir_close(&dir);

tinydir_dir dir;
int i;
tinydir_open_sorted(&dir, "/path/to/dir");
for (i = 0; i < dir.n_files; i++)
{
	tinydir_file file;
	tinydir_readfile_n(&dir, &file, i);
	printf("%s", file.name);
	if (file.is_dir)
	{
		printf("/");
	}
	printf("\n");
}
tinydir_close(&dir);

See the /samples folder for more examples, including an interactive command-line directory navigator.

ANSI C, or C90.

POSIX and Windows supported. Open to the possibility of supporting other platforms.

Simplified BSD; if you use tinydir you can comply by including tinydir.h or COPYING somewhere in your package.

• Limited path and filename sizes
• Possible race condition bug if folder being read has changing content
• Does not support extended-length path lengths in Windows - paths are limited to 260 characters. See https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry
