The EXTRACT utility allows you to extract a file from a CAB cabinet archive file. Using the following command
EXTRACT d:\path\archive.cab filename.ext
will extract the specified file from the cabinet file and place it in the current directory. If you want to extract files and place them in a directory different from the current one at the /L switch followed by the target directory name where you want to place the file.
EXTRACT d:\path\archive.cab filename.ext /L c:\targetdirectory.
Note that the space between the /L switch and the target directory is required. Like for all DOS commands, if the target directory name contains embedded spaces or other special characters, then it must be enclosed in quotation marks.
