Scrap Packed Explorer

This App allows you to create or modify the contents of .packed files for the Game Scrapland.

See also the Scrap Hacks Project by Earthnuker (on gitdab) for an alternative implementation using python

About "packed" files

.packed Files are used by the Game Scrapland to have most of the game data merged into one big data container. The contents are neither encrypted nor compressed. Therefore modifying it is relatively straight forward.

But before this project there was no real userfriendly way to do that and the goal of this project was to enable modding for users who do not really want to think about the details of this filetype.


How to use

The App can work in 2 different modes: GUI and CLI. (Graphical User Interface vs Command Line Interface) To run App with GUI you run ScrapPackedExplorer.exe or ScrapPackedExplorerCombined.exe (or their 32-Bit variants). To run App with CLI you must run ScrapPackedExplorerCli.exe or ScrapPackedExplorerCombined.exe (or their 32-Bit variants) with command line arguments.

Although the Combined version also contains the whole GUI, a separate GUI-only version is distributed, because when you launch the GUI from the Combinded-Version (by not providing any command line arguments) a cmd window flashes for a split second. If you are ok with this you can use the Combined version for both GUI and CLI mode.

The Version without Cli or Combined in its name supports only the GUI mode but also has no flashing cmd window on startup.


GUI

!TBD! GUI is nearly usuable but some key features are missing for fully functional usage. Updating this README chapter is part of the GUI issue (#2)


CLI

A basic call looks like this:

ScrapPackedExplorerCli.exe <path-to-the-packed-file> <subcommand> <options>

You can also specify the subcommand before the path to the packed file.

List of the subcommands:

Subcommand Description
add Add file to the container
remove Remove a file from the container
rename rename a file or folder inside the container
extract Extract/unpack a file from the container
list List or search files and folders in the container
cat Print content of file inside of containerist or search files and folders in the container
help Display more information on a specific command.
version Display version information.

Add

-d, --packed-path (Default: ) What path to put the source file(s) into
-o, --output-packed-file (Default: ) Where to store the new .packed file. Modify input if not provided.
