ARCHIVED: In Mac OS and Mac OS X, how do I compress and archive folders, files, and applications with StuffIt?
In Mac OS X, applications are often distributed as disk images or GNU zipped tar files. However, in the classic Mac OS (i.e., 9.x and earlier), DOS and Unix archive and compression formats aren't often used. Because of its dual-forked file structure, Mac-specific formats have emerged instead. One in particular, StuffIt, has become the de facto standard. With StuffIt, it is possible to compress files or compress and archive entire folder hierarchies into a single stuffed file.
Smith Micro has two applications for creating StuffIt archives: StuffIt Deluxe and DropStuff. StuffIt Deluxe is a more expensive commercial product with DropStuff built into the application. DropStuff is also available as part of the StuffIt Standard Edition suite of applications.
To create a StuffIt archive with DropStuff, select the icon or icons
(folders or files) you want to archive and compress, and then drag the
item(s) to the
DropStuff icon. Release the mouse button when
DropStuff icon darkens and DropStuff will automatically
perform the compression, creating a single
containing the compressed item(s).
By default, if you drop a single file onto DropStuff, it will create a
stuffed file with the same name, except it will have the
.sit extension. Likewise, if you drop a single folder
(regardless of its contents) onto the
DropStuff icon, it will
create a stuffed file (containing the compressed folder and all its
contents) with the same name as the folder, but with the
.sit extension added. If you drop more than one file or
folder onto the
DropStuff icon, it will create a file called
Alternately, instead of using drag and drop, double-click the
DropStuff icon, and then from the
File menu, select
Stuff... . A window opens that allows you to
select and add or remove folders and files to a new StuffIt archive.
Once you've finished adding files you want to be stuffed, click
Stuff. Then choose a name for the archive and save it.

document, and click
StuffIt Deluxe will launch a window that can be used like a
Finder window. You can drag files and folders to the window,
and they will be added to the archive. Likewise, dragging files or
folders from the window will remove them from the archive. You can
even double-click folders in the
StuffIt window to modify
their contents. Once you are finished, close the
If you wish to modify the contents of the archive later, just drag its
icon over the
StuffIt Deluxe icon and a window with its
contents will open. Alternately, double-click the
Deluxe icon, and from the
File menu, select
Open... . In the dialog box, select the archive you
wish to edit and click
