Hi @Ethan_Buttazzi, how did you install Aseprite? through the .exe installer? If that is the case you can uncheck the .ase association in the installer steps.
Anyway there are two problems that we might fix for future versions:
- Don’t check the .ase extension association with Aseprite by default
- Disable the association when using Steam (installing Aseprite from steam will run a Steam script to associate the .ase extension with Aseprite)
It’s a shame because Microsoft has created a mess to handle the same file format from multiple apps. E.g. you have to modify the registry, restore it, or the original app has to restore the registry keys, etc. The situation on macOS is quite different: each application has an XML saying “I can open X type of file”, so that’s all, then you have the choice to select the app to open that kind of file.
