# Filesystem

To browse files, use os.90s.dev/#sys/apps/filer.app.js

# File format

The file system of os.90s.dev is very simple:

• Every directory, including root drives, has the format <dir>/

  • The trailing / is part of the folder name

  • For example sys/ and sys/apps/ are two folders

• Drives are just (special) folders

• All files are text-based, binary is not supported

# Root drives

• sys/ is read-only and contains core system files

• usr/ is stored in IndexedDB

• net/ is backed by a shared database

• You can mount local file system drives to given names

  • NOTE: .js files are stored as .tsx on mounted drives

# Accessing files in usr/

Because sys/ and net/ are the same for everyone, libraries and apps that make use of these will work the same for all users.

It is possible to use usr/ in apps and libs, however, the files may not exist or may be different, depending on what the user has stored there!

There are currently no conventions for what files in usr/ should be expected. This is something that the community will surely decide on as needed.
