User-Startup and Startup-Sequence 

Related Preferences Although not always handled through a graphical preference editor, startup configuration is a major part of AROS customization. 

Important startup files include: 
S:Startup-Sequence
S:User-Startup

These files can define: 
which commands run at boot
which assigns are created
which services are started
which patches or tools are loaded
which environment variables are set

Beginners should be careful when editing startup files, because mistakes may prevent the system from booting correctly. 

ENV and ENVARC 

AROS uses environment variables in a way similar to AmigaOS. Two important locations are: 
ENV: — current temporary environment settings
ENVARC: — permanent environment settings saved across reboots

Many preferences are stored in ENVARC: and copied or loaded into ENV: during startup. 

This means: 
changes in preferences are often saved permanently in ENVARC:
the running system uses active settings from ENV:
deleting or damaging files in these locations may reset or break preferences

GUI Preferences and Config Files 

Not every setting in AROS is managed through a single central control panel. 

Preferences may be stored as: 
separate preference files
tooltypes
environment variables
configuration files
startup script entries
application-specific settings

This is typical for Amiga-like systems and gives advanced users a lot of control. 

ToolTypes 

Many AROS programs and icons support ToolTypes. ToolTypes are settings stored in icon information. 

They may define: 
program options
startup parameters
window size
screen mode
paths
device names
feature switches

A beginner can think of ToolTypes as small configuration options attached to an icon. 

DOS Preferences and Assigns 

AROS uses Amiga-like logical paths called assigns. 

Examples include: 
SYS:
C:
S:
Prefs:
Tools:
Utilities:
Work:

Preferences and startup scripts may define or rely on these assigns. Assigns make it possible to refer to important system locations without always using full physical paths. 

Shell Preferences 

The AROS Shell can also be customized. 

Typical shell-related preferences include: 
shell window size
default shell fonts
command search paths
aliases
prompt appearance
startup commands
environment variables

Some of these settings may be configured through startup scripts rather than a graphical preferences program. 

Compatibility Preferences 

Depending on the AROS version and distribution, there may be settings related to compatibility with AmigaOS-style software. 

These may involve: 
file system behavior
library paths
assigns
legacy program settings
icon handling
screen handling

Because AROS is Amiga-inspired but not identical to AmigaOS, compatibility settings can be important when running older or ported software. 

Storage and Device Preferences 

Some AROS setups include tools or configuration files for storage devices. 

These may involve: 
partitions
disk devices
file systems
mount lists
device names
boot volumes

On Amiga-like systems, device configuration is often more visible to the user than on modern consumer operating systems. 

How Preferences Are Usually Opened 

Preferences are usually found in a drawer such as: SYS:Prefs or simply: Prefs: From there, the user can open individual preference programs. 

Common examples may include: 
ScreenMode
Locale
Input
Font
Palette
Pointer
Time
AHI
Wanderer
Zune or MUI-related tools

The exact list depends on the AROS distribution. 

How Preferences Are Saved 

Most preference editors usually offer buttons such as: 
Save
Use
Cancel

Their meaning is important: 
Use applies the setting only for the current session.
Save applies the setting and stores it permanently.
Cancel closes the editor without applying changes.

This behavior is very typical for Amiga-like systems. 

Why AROS Preferences Are Important 

Preferences in AROS are important because they define both the appearance and the behavior of the system. 

They control: how the desktop looks
how windows react
how the mouse and keyboard feel
which language and region are used
how sound works
how programs display their interfaces
how the system starts
how paths and assigns are configured

For beginners, the most important preference tools are usually: 
ScreenMode
Locale
Input
Wanderer
Font
AHI
Time
Zune or MUI preferences

Short beginner-friendly summary 

AROS preferences are the system settings of AROS. They are usually stored in the Prefs: drawer and allow the user to configure display, language, keyboard, mouse, sound, desktop behavior, fonts, colors, themes, startup behavior, and program interfaces. Unlike some modern systems, AROS keeps many settings in separate preference tools and configuration files, which gives the user a lot of control but can feel unusual at first.Wanderer is the desktop environment of AROS, comparable to Workbench on classic AmigaOS. It is the part of the system where users see drives, drawers, program icons, files, and windows. For beginners, Wanderer is often the main place for everyday work.
