Actually, after converting things to the lua io library, the crash has stopped happening. Not sure what made the difference, but seems to be working smoothly!

Added test files to the repro. The steps to get it to crash: 1) create a new files, 2) open test.cos, 3) create a new file again, 4) open test.cos again. Thanks for checking!

In the meantime I'm converting my nativefs stuff to the lua io library. Totally forgot about that one. Thanks again!

I don't see any way to read/write files using lovefs besides sounds, fonts, and images. I'm using custom filetypes. I'm also running into an issue where if I load a file after I've already loaded one, the program just closes without providing any errors. Any ideas why that might happen? Here's what ...

Fixed it by search-replacing "wchar_t" with "char" in nativefs.lua.

Sadly nativefs and lovefs don't play well together. I think it's due to conflicting ffi.cdef's. Poking around to see if I can get them to work together, otherwise I'll use them as inspiration for my own file load/save dialog.

Thanks for explaining!

So does Love2D prevent you from accessing files at all outside the folder the program is in? Trying to call getInfo on files based on an absolute filepath ("C:\...") return nil.

LoveFS looks perfect! It's even using LuaFrames, which is the GUI framework I went with. Thanks so much!

I'm working on a little modding tool in Love2D, and I'd like to have a way for the user to open/save files with a system file dialog. Is there a library or anything to support that? Thanks!
