[edit] The System file before System 7
Before System 7, the System file just lay on the root level of the System Folder. It could not be opened by the user.
[edit] The System file in and after System 7
With the release of System 7, the System file became a suitcase. The following items could be dropped onto the System file (or be rerouted to the System file if it was dropped on a closed System Folder icon in Mac OS 8 through Mac OS 9):
- Keyboard layouts
- Fonts (until System 7.1)
- Function keys or Fkeys
- WorldScript files
- System 7 Sounds
[edit] The System file in Mac OS X
The System file in Mac OS X was relocated to System > Library > CoreServices, and is no longer openable. A double-click will result in the error dialogue box, stating "Item "System" is used by Mac OS X and cannot be opened".
[edit] The System file in list views
In Mac OS X, the System file appears in list views as a document icon with the upper-right hand corner folded down.
Before Mac OS X, however, the System file appeared in list views as a document icon with the upper-left hand corner folded down.
