Can't move files after opening them

[firas5673]

I can't move game files after loading them with UnityPy.
I call a function that has env = UnityPy.load(file_path) inside it, then after that when I try to move the file to another location, I can't do that.

Here's a simplified version of the code:

The function:

def is_excluded_file(file_path):
    try:
        env = UnityPy.load(file_path)
    except:
        return False
    for path,obj in env.container.items():
        if condition(path):
            return True
    return False

for file_path in file_walker(assetbundle_path): #recursively yields every file's path in the folder
    if is_excluded_file(file_path):
        dir_path  = os.path.dirname(file_path)
        nested_path_lib = Path(os.path.join(move_folder, dir_path))
        nested_path_lib.mkdir(parents=True, exist_ok=True)
        shutil.move(file_path, os.path.join(move_folder, file_path))

I get an error at that last line, saying that it's being used by another process (which is UnityPy).
Is there a way to "close" this process?

For a temporary solution, you can "record" the files you want move to a txt file, then run another script to move them.

Yeah, I did exactly that. My project is small, but I could see this becoming an issue in bigger projects.

UnityPy doesn't explicitly call close on opened handles.
It just drops the object, so the garbage cleaner will at some point close the file handle.

You basically have three ways to work around this.

1. pass file handles to UnityPy.load instead of paths, and close them yourself
2. force a gc cleaner pass (rather expensive) after you're done with the env
3. iterate over the env content and close all streams (bit more tricky)
