About GCFScape

GCFScape is a little device that can open up and also extract from GCF documents that are used by Heavy steam for video game web content storage. It can be downloaded and install.

GCFScape 1.7.1 or far better is called for to open up VPK files. To surf the base web content of a video game making use of VPK, you need to open the index file pak_01_dir. vpk.


Tip: When you set up GCFScape make certain you associate GCF data with GCFScape so they'’ ll open immediately. The files will be provided icons if this has been done.

When a GCF is opened, the program will resemble this:

Clicking the little button, you can browse the folders clicking on them so they expand as well as show subfolders thus, after that clicking on a folder will certainly reveal the materials to the right:

Right clicking a documents will certainly raise a context menu where you can draw out from:

Clicking this will bring up a window where you can choose your conserve area:

Clicking OK will draw out the data to your picked area.follow the link gcfscape At our site

Sustained Formats

In addition to GCF documents, GCFScape additionally supports Half-Life BSP, NCF, PAK, VPK, WAD, and also XZP data.


The adhering to options are offered inside the options menu in GCFScape:


Enable verbose logging (made it possible for by default). Disable this alternative to minimize log outcome. This can be useful when you are extracting big amounts of data and also just intend to be notified of mistakes.

Submit Mapping

Enable Windows file mapping (made it possible for by default). File mapping is an efficient method of random data gain access to. Some running systems have problems with data mapping (specifically Windows 98) and also might produce mistakes; disable this alternative in such cases.

Quick Submit Mapping

Map the entire file to memory (instead of pieces of it as required). Efficiently caches the file in memory. Can speed up things up if you have sufficient totally free memory. Some running systems have issues with documents mapping (particularly Windows 98) as well as might produce errors; disable this option in such instances.

Unpredictable Access

Enable unstable documents gain access to (allowed by default). By default, Steam loads.gcf data in read/write setting and also is liable to alter their contents at any time (as updates happen). Ought to this take place, GCFScape would become unpredictable as well as likely accident. Volatile gain access to enables you to open up GCF files packed in Steam at your own risk. It is typically secure and can prove valuable for checking out which submits Steam is updating.

Write Access

Enable compose data gain access to (disabled by default). Create gain access to provides GCFScape the ability to customize certain files and is not compatible with unstable gain access to for the instability a mix of both would certainly trigger. This choice is needed for GCF defragmentation.


In variation 1.5.0, GCFScape included the ability to confirm GCF files. This process computes a collection of hybrid CRC 32 and Adler-32 checksums for each and every documents within a GCF data and also compares each checksum to the checksums precalculated and also stored within the GCF file. This function gives a quick choice to Steam for examining GCF corruption and listing corrupt and incomplete documents, but can not fix damaged GCF data as Heavy steam can.

To confirm all or part of a GCF file utilizing GCFScape, complete the following actions:

  1. Release GCFScape.
  2. From the File food selection, open your GCF documents.
  3. Search to the leading level folder you wish to confirm (origin for the entire GCF documents).
  4. Right click on the folder and also pick Validate.
  5. Repeat actions 2-4 for each GCF data you desire to verify.


In variation 1.6.0, the capability to defragment GCF data was added to GCFScape. This attribute was added after several tests by Nem indicated that Vapor'’ s built in defragmenter did not always totally defragment a game'’ s GCF files. As a matter of fact, Vapor would certainly commonly incorrectly report a fragmentation of 0% when the true fragmentation was as high or more than 10%, a worth extremely detrimental to performance.

GCFScape specifies the fragmentation proportion to be the number of utilized clusters that are out of order divided by the overall number of utilized clusters. The initial collection in a documents can never be out of order, so a data that includes just one cluster (normally < <8192 B) can never be fragmented. At 10% fragmentation, a regular ~ 785 MB GCF data (about 100,000 clusters at 8192 B per collection) would require, usually, one look for procedure for every 80 KB of data check out. You can watch the fragmentation of any kind of documents or folder (origin for the whole GCF documents) by examining its buildings.

To defragment your GCF files using GCFScape, complete the adhering to actions:

  1. Closure Steam.
  2. Launch GCFScape.
  3. In the Options food selection, allow Write Accessibility as well as disable Volatile Access.
  4. From the File menu, open your GCF file.
  5. From the Tools food selection, choose Defragment.
  6. Repeat steps 4-5 for each GCF file you desire to defragment.

Note: The defragmentation process is rather sluggish, however can be canceled and resumed any time.

Running GCFScape

GCFScape requires. WEB 4.0 (or later), as well as Visual C++ 2010 Runtime (x86 or x64) to run.

These requirements relate to all running systems, MacOS and Linux individuals will certainly require to mount these in order to run GCFScape through Wine.
