What is a .SEA file?

The file extension .SEA stands for Self-Extracting Archive. This type of file is a compressed archive, which means it contains one or more files that have been reduced in size. The unique feature of a .SEA file is that it can decompress or "unzip" itself without the need for additional software. This makes it very convenient for sharing multiple files or large files, as the recipient does not need special software to open it.

These .SEA files are often created using a program called StuffIt SEA Maker, which is part of the StuffIt Deluxe package for Mac OS X. However, they can also be made using other software utilities available on Mac OS Classic, such as StuffIt, Disk Doubler, or Compact Pro. These tools help in compressing files to save space or to make them easier to send over the internet.

To open a .SEA file, you can use several programs, including Smith Micro StuffIt Deluxe, which is available in versions for both Windows and Mac (specifically Smith Micro StuffIt Deluxe Mac 16). Another option for Mac users is The Unarchiver, which is a free program capable of handling many different types of compressed files, including .SEA files. These programs help in extracting the contents of the .SEA file so you can access the files inside.
