[Python] How to construct an in-memory virtual file system and then write this structure to...

I'm looking for a way to create a virtual file system in Python for creating directories and files, before writing these directories and files to disk.

Using PyFilesystem I can construct a memory filesystem using the following:

>>> import fs
>>> temp_dir = fs.open_fs('mem://')
>>> temp_dir.makedirs('fruit')
SubFS(MemoryFS(), '/fruit')
>>> temp_dir.makedirs('vegetables')
SubFS(MemoryFS(), '/vegetables')
>>> with temp_dir.open('fruit/apple.txt', 'w') as apple: apple.write('braeburn')
...
8
>>> temp_dir.tree()
├── fruit
│ └── apple.txt
└── vegetables


Ideally, I want to be able to do something like:

temp_dir.write_to_disk('<base path>')


To write this structure to disk, where <base path> is the parent directory in which this structure will be created.

As far as I can tell, PyFilesystem has no way of achieving this. Is there anything else I could use instead or would I have to implement this myself?
