Temporary and External files are files located in two special directories.

 

Temporary Files are files located in the temporary setup directory (%TempSetupDir% variable). These files are extracted in the beginning of setup program and are removed from end-users computer when the setup program is closed. To include a temporary file in your setup project select Project > Temporary Files menu command, then select Editor > Add Files menu command.

 

External Files are the files located in the same directory of the setup program (%SourceDir% variable). The files included as external files are not compressed, they are just copied to the output directory, and you will need to distribute them with your setup program file. To include an external file in your setup program select Project > External Files menu command, then select Editor > Add Files menu command.
