That is, you don't have a single "/" root directory that all other filesystems are found under. | Like Windows, but unlike OS-X and Linux, the Amiga has a **multi-rooted** filesystem.

The equivalent on Linux are the files under /dev/. They are not part of the filesystem like in Linux, but they are important to be aware of, especially since their names makes them look the same as volumes and assigns. |
| Volumes are actual filesystems mounted with a name. E.g. commonly System:, Work: etc., that refer to a filesystem on a partition on one of the disk devices. | Volumes are actual filesystems mounted with a name.

| + | ===== ".info" files ===== | ||
| + | |||
| + | ".info" determine whether a file is visible on the Workbench by default or not. To be visible, it needs to have a ".info" file unless the user selects to see all files. The ".info" file also contains additional information, such as "tooltypes" that can be used to pass configuration information to the program. The ".info" file can contain a custom image. | ||

| + | ===== Permissions ===== | ||
| + | |||
| + | AmigaOS is not a multi-user system. As a result, files does not have users. | ||
| + | |||
| + | For a file to be executable, it needs to have the "e" permission set. | ||

| + | TODO: Protect example + how to do it from Workbench / file managers. | ||
