Open SED File
There are a couple of different applications for files with the SED extension, below:
IExpress Self Extraction Directive File
In this application, the SED format is a type of file created by the IExpress Wizard, a native-integrated Windows program that is used to create Windows installers.
This SED file contains the options used to create a software installation package.
The SED file includes the files to be created in the package, the file name of the output package, the pop-ups for the installation process, and other options.
SED files are used by the IExpress wizard to create self-extracting executables, therefore, they are ideal for creating software distributions.
sed Script
In this case, the SED format and extension file is a script used by 'sed' or Sequence Editor, a Unix command line utility used to filter and modify text.
This SED format stores one or more statements, which contain pattern matches and substitutions, and is typically used to store reusable sed statements.
