What is a .USTAR file?
The .USTAR file extension stands for Uniform Standard Tape Archive Format File. This type of file is an archive, which means it's used to store multiple files together in one single file. The .USTAR format is a special kind of archive file because it is based on the .TAR format but with some improvements. These improvements include a longer header, which is like a detailed label on the file, allowing for longer names of the files stored inside the archive. It also allows for more detailed information about each file to be included. Unlike some other archive formats, .USTAR files are not compressed, so the size of the archive is just the total size of all the files inside it, without any reduction.
To open a .USTAR file, you can use several different programs. Two versions of Smith Micro StuffIt Deluxe can handle these files—one for Windows and one for Mac (specifically Smith Micro StuffIt Deluxe Mac 16). Another program that can open .USTAR files is Corel WinZip. These programs are designed to work with various types of archive files, including .USTAR, and they can help you view, create, or extract the contents of these archives.
Since .USTAR archives are an extension of the TAR format, many modern applications that can open TAR files should also be able to handle .USTAR files. This means if you already have a favorite program for dealing with TAR files, it might work for .USTAR files as well.
