Typical GCFScape Window

Overview

GCFScape is a small tool that enables you to browse through the GCF files that are utilized by Steam for game content storage. This could be useful for making model mods or extracting in game sounds.

Extraction

Extracting files from GCF's couldn't be simpler with this utility as it's like the Explorer folder tree format. But if you're still stuck, here's how to extract files:

When you install GCFScape make sure you associate GCF files with GCFScape so they'll open straight away, they'll look like this if they're associated:

Double clicking one of these will open GCFScape. Say, you opened the Counter-Strike Source Shared GCF, the program will open and appear like this:

Clicking the little Plus.PNG button, you can browse the folders clicking on them so they expand and show subfolders like so, then clicking on a folder will show the contents to the right:

Right clicking a file will bring up a context menu from where you can extract from:

Clicking this will bring up a window where you can choose your save location:

Clicking OK will extract the file to your chosen location.

Supported Formats

In addition to GCF files, GCFScape also supports Half-Life BSP, PAK, WAD, and XZP files.

Options

The following options are available through the options menu from within GCFScape:

Verbose
Enable verbose logging (enabled by default). Disable this option to reduce log output. This can be useful when you are extracting large amounts of files and only want to be informed of errors.
File Mapping
Enable Windows file mapping (enabled by default). File mapping is an efficient method of random file access. Some operating systems have problems with file mapping (in particular Windows 98) and may produce errors; disable this option in such cases.
Quick File Mapping
Map the entire file to memory (instead of pieces of it as needed). Effectively caches the file in memory. Can speed things up if you have sufficient free memory. Some operating systems have problems with file mapping (in particular Windows 98) and may produce errors; disable this option in such cases.
Volatile Access
Enable volatile file access (disabled by default). By default, Steam loads .gcf files in read/write mode and is liable to change their contents at any time (as updates occur). Should this happen, GCFScape would become unstable and likely crash. Volatile access allows you to open GCF files loaded in Steam at your own risk. It is generally stable and can prove useful for examining which files Steam is updating.
