Legacy:UPKG File - Unreal Wiki

# Legacy:UPKG File

### From Unreal Wiki, The Unreal Engine Documentation Site

This type of file is used to tell ucc what flags to set to the current package. They are placed in the Classes folder.

The upkg file is a helper file (such as the INI file or INT file). As with the other two, this, as well, is a simple text file which can simply be edited in Notepad. This is very similar to the int file in behavior, with the difference that the int is used after compilation to add new things to the game, while the ukpg is used before compilation.

They consist of one or more sections which start with the section Flags marked in brackets followed by Key=Value boolean pairs.

    [Flags]
    AllowDownload=False
    ClientOptional=False
    ServerSideOnly=True
    ...
