What are StuffIt Files?
StuffIt files are files compressed by Aladdin Systems
compression software. These files have a '.sit' file extension. They
take up significantly less room than expanded files and improve download
time and reliability.
ADInstruments Macintosh software available from this web site has been
compressed into StuffIt files. These files must be expanded using Aladdin
Systems StuffIt Expander v5.1.2 or later, before they can be used.
Note: ADInstruments Windows software available from this web site is
saved in executable '.exe' file format. It is not compressed and does
not need to be expanded before use.
StuffIt Expander for Macintosh
StuffIt Expander lets you expand Mac files that have
been compressed into StuffIt files. If you do not already have StuffIt
Expander, then you can download it free of charge from Aladdin Systems
web site: www.aladdinsys.com/expander/index.html
StuffIt Expander v5.1.2 or later is required. Earlier versions will fail
to work, or may give misleading messages such as the files are corrupt
or damaged.
Note: StuffIt Expander is also available for Windows. It allows you
to expand files compressed in '.zip' , '.sit' and other file formats.
You can download it free of charge from Aladdin Systems web site: www.aladdinsys.com/expander/index.html.
Downloading and Expanding StuffIt
Files
To download a '.sit' file from the web site, simply
click the appropriate link. The file will download onto your computer.
Depending on how your browser is configured, the downloaded file may
then be expanded automatically (settings in the Preference menu of your
browser determine this). If not, you will have to expand it before you
can use it. To expand a stuffed file manually, simply drag it onto the
StuffIt Expander icon, or open it from within the Expander program.
An expanded copy of the file with an appropriate file extension will
be placed at the same level as the compressed file. You can now use this
expanded file as usual.
