search file extention in sub directories

[DeaD_EyE]

You can try this:

def find(path, ext):
    for root, dirs, files in os.walk(path):
        for file in files:
            if file.endswith(ext):
                fp = os.path.join(root, file)
                yield fp

I guess, it takes the same time. Maybe you repeat the search twice or more. Try it more then one time.
os.walk and glob is using os.scandir, which is not collecting the stat information, which is faster.
