Windows applications should not store static files common to all users (even if that is just one user) in the appdata folder.
Common static files like:
- Executables (.exe, .dll, .jar, .bin, .js...)
- Collections (.cab, .zip, .7z...)
- Installation (.msi...)
- Configuration (.ini, json...)
- Data (ryo, .db...)
These should be stored in c:\ProgramData (there is a hint in the very name).
Of course, you would ask why would anyone care? That is a good question. The answer is that when backups are made of the appdata folder, it is a waste of backup time and space to store these files; especially the executables which can be very large in aggregate if all the user wants is data that pertains just to them (after all, these files are in c:\Users\<userid>\...).
And if there are multiple users, then these files a mere duplicates wasting storage space.
