How to open SIT! file?

The most common problem when using StuffIt Expander Archive Format is that a specific SIT! is not associated with the program. This causes the file SIT! to open by system applications not designed for this purpose, or to display a message that there is no associated program.

The first thing you should do is just "doubleclick" on the SIT! file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install StuffIt Deluxe

An often overlooked issue is to make sure that StuffIt Deluxe is installed on the computer. The easiest method is to use the system search engine by entering the program name StuffIt Deluxe in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open SIT! files.

Programs to open SIT! file

Remember to download programs supporting SIT! files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of StuffIt Deluxe with SIT! files

However, it may happen that the application itself does not cause the SIT! file to open in the StuffIt Deluxe application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the SIT! file with the StuffIt Deluxe application.

Step 3. Update StuffIt Deluxe to the latest version

The fault may also lie with the StuffIt Deluxe program, it is possible that StuffIt Expander Archive Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the Smith Micro Software, Inc. website and install the latest version.

Step 4. Check for the following problems with the SIT! file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The SIT! file may be unusually small compared to the original file. This is most often caused by a problem while downloading the SIT! file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our SIT! file. As a result of the scan, sometimes it is not possible to recover SIT! files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of SIT! file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged SIT! files. You can restore the file from a backup or use Smith Micro Software, Inc. help.
The program can also signal the fact of encryption. The encrypted SIT! files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move SIT! to a different directory.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the SIT! file while scanning. If the problem persists, restart the machine.
