Safe Mode (disable functionality unsuitable for inexperienced users)
With safe mode enabled, certain navigation functionality is hidden away. Basically any functionality that can cause damage (erasing/moving/copying files for example). If you are building a home entertainment system where inexperienced users have access, you may want to enable this feature.

Use keyboard input to quickly search and input data through navigation interfaces
With this setting enabled, when a navigation interface is visible, keyboard input is used to quickly search through the active navigation interface. When disabled, keyboard input is used to control Zoom Player functionality (play/pause/etc...).

Limit quick search to item-list navigation interfaces (media library, play history, etc...)
When enabled, the keyboard input quick search feature will be limited to navigation interfaces that list dynamic entries (such as file names). Interfaces with fixed entries (such as color control, equalizer, etc) will route keyboard input to player control (play/pause/etc).

Show File Extensions (playlist, file and media library navigators)
This setting controls whether Zoom Player should display (or not) file extensions (".AVI" for example) within the navigation interfaces.

Show File Sizes (file and media library navigators)
This setting controls whether Zoom Player should display (or not) file sizes within the navigation interfaces.

Show Subtitle files (file and media library navigators)
This setting controls whether Zoom Player should list (or not) subtitle files within the navigation interfaces.

Show Archive files (file and media library navigators)
This setting controls whether Zoom Player should list (or not) archive (zip/rar/etc...) files within the navigation interfaces.

Show Hidden files (file and media library navigators)
When enabled, Zoom Player will show files/directories that are marked as "hidden" by windows.

Show "Play all files in this Directory" in the main file list (file and media library navigators)
By default the "Play all files in this Directory" function is part of the function list when clicking the Navigate-Right key on a media file. With this setting enabled, the "Play all files in this Directory" function is made accessible in the main file list.

Close Navigator when opening a new file (playlist, file and media library navigators)
When opening a new file using the Enter/Select key within navigational interfaces, you can choose whether the interface should close or remain open.

Copy / Move operations should overwrite existing files
Some of the navigation interfaces (Media Library, File Browser for example) have the functionality to copy/move files around. This setting controls whether copied/moved files overwrite existing files with the same name at the target directory. With this setting disabled, existing files will be skipped.

"Del" key moves media files to the recycle bin (with confirmation)
By enabling this setting, you are allowing Zoom Player to erase files with the Del key.

Disable Scroll Acceleration
By default, Zoom Player accelerates scrolling of navigation list elements. The reason for this is that most remote controls don't have scrolling capabilities and clicking a "move down" button when dealing with large lists can be aggravating. For this reason, Zoom Player activates acceleration when clicking the up/down navigation keys quickly. This setting allows you to disable this behavior.

When no chapters are specified in the Chapter Navigator, show the Playlist Navigator
Not all media files have chapter information. With this setting enabled, when opening the Chapter Navigator with media files that don't have any chapter information, Zoom Player will automatically open the Playlist Navigator.

Always sort directories first (file and media library navigators)
When enabled, Zoom Player will sort directories first followed by the files. When disabled, the files and directories will be sorted as one group.

Include sub-directories when playing all files in a directory
This setting controls whether sub-directories should be scanned for media files when opening all the files in a directory through the navigation interfaces.

Nav-Left goes up a directory before entering the Drive/Category list
By default, using the Navigate-Left key will move to the Drive List or Category List (depending on the navigation interface being used). With this setting enabled, the Navigate-Left key will first go up directories until reaching the root directory before entering the Drive/Category list.

Highlight previously viewed files
In combination with the "Remember media position" feature, this setting can enable special highlighting in the media library and file browser navigation interfaces that will highlight files that were already played. The downside to this is that it takes quite a bit of CPU time and may slow down the interfaces if activated.

Do not show the "Library Filter Mode" page
In the Media Library navigation interface, pressing "Left" in the category list will open the "Library Filter Mode" interface allowing you to choose between Audio/Video type content. If you do not require filtering, enabling this setting will have pressing Left on the category list go directly to the main navigation interface.

Pause playback when opening file browsing interfaces with a video playing
When enabled, opening file browsing navigation interfaces will pause the video. Does not affect audio playback.

Right-Clicking with the mouse closes the navigation interface
When enabled, using the mouse's right button will close any open navigation interface.

Route Information navigator keyboard input to player control
When enabled and with the Information navigation interface open, all keyboard input is routed to player control (play/pause/etc...).

Do not share the background of inactive navigation text lines
When enabled, only the active item will have a background image, all other lines of text will be drawn against the navigation background image (with some navigation skins, this feature may help unclutter the display).
