Using StuffIt Expander

The quick-and-dirty instructions for using StuffIt Expander (path: Applic a tions/Utilities/StuffIt Expander) are as follows: Drag your archive file(s) (.hqx, .bin, .sit, .tar.gz, and so on) on top of the StuffIt Expander archive. StuffIt will launch and unarchive the selections.

Alternatively, start the Expander application; then use Expand (Command+E) from the File menu to choose the files to expand.

There are a number of settings that can fine-tune how StuffIt expander deals with archive files after they have been extracted, and the text files within. If you use StuffIt archives in a cross-platform environment, these options can help reformat files for better viewing on the Macintosh. Improper use can also corrupt source code files.

Preferences

Open the StuffIt Expander preferences from the application menu. There are eight categories of options that can be set. Switch between each area by clicking the appropriate icon on the left side of the preference window.

Expanding

The Expanding preferences, displayed in Figure 8.1, control what happens to archives as they are being extracted and after the extraction has completed.

You can fine-tune the process of expanding archives with the following settings:

Joining

The Joining panel, shown in Figure 8.2, controls how split archives are handled. By default, StuffIt Expander will attempt to join segmented files, and then automatically expand the completed archive. Use the check boxes on this screen to alter these settings or configure StuffIt Expander to automatically remove individual segment files after they are joined (the complete file will remain).

Figure 8.2 Joining segmented archives is controlled by the Joining panel.

Cross Platform

The Cross Platform settings, shown in Figure 8.3, determine how StuffIt will deal with text files that it finds within an archive. A user can choose to convert text files to Macintosh format when StuffIt detects text, or to never convert files.

Disk Images

The Disk Images panel controls what StuffIt will do when it encounters a disk (ShrinkWrap) image. This feature is currently unavailable in Expander for Mac OS X.

Destination

As the panel name suggests, Destination sets the location where unarchived files will be stored. Figure 8.4 demonstrates the Destination configuration panel.

The following options are available under the Destination panel:

Watch Folder

Setting up a Watch Folder can be useful if you've created a drop box for other users or simply want a place to put files and have them automatically expanded as they arrive. The Watch Folder panel is shown in Figure 8.5.

Control the functionality of your Watch Folder with these settings:

Version Check

Use the check box on the Version Check panel to enable StuffIt Expander to check online for new versions. This feature is on by default and is not at all intrusive. Uncheck the feature to prevent your system from contacting Aladdin Systems. Figure 8.6 displays the Version Check panel.

Internet

The final configuration panel, Internet, is used to set the file types that StuffIt Expander is registered to handle on the Mac OS X system. As shown in Figure 8.7, you can mix and match among the 18 available archive and encoding types. Click the Use StuffIt Expander for all available types button as a shortcut for clicking all the check boxes.
