File extension .SITX

File description

Files with the SITX file format are generally related to the Smith Micro StuffIt file archive and compression utility application.

The 7th Version and the later versions of the application create as well as save compressed file archives with the SITX format. They enable users to take a batch of files or a large file and then compress them into smaller archive files to save the disk space and make it extremely easy to share the files over the Internet. The SITX file extension makes use of the proprietary ATOM compression technology, which is useful for higher compression rates compared to the conventional .SIT format.

Remember that you need to download a program to support a particular file type. So first look through the entire contents of the website to select a program to support just the file you have.

Other possible reasons why your .SITX file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .SITX file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .SITX file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .SITX file, so download the update and check again.

2. Incorrect .SITX file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

  • Right-click the .SITX file
  • Go to the "Open with" - then "Choose default program ..."
  • Locate the appropriate application
  • Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
