About GCFScape

GCFScape is a tiny tool that can open and remove 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 much better is required to open VPK data. To surf the base material of a game making use of VPK, you need to open up the index documents pak_01_dir. vpk.


Suggestion: When you install GCFScape make certain you link GCF files with GCFScape so they'’ ll open quickly. The data will certainly be given symbols if this has been done.

When a GCF is opened, the program will certainly look like this:

Clicking the little switch, you can browse the folders clicking on them so they expand and also show subfolders like so, then clicking a folder will show the materials to the right:

Right clicking a data will bring up a context menu where you can remove from:

Clicking this will certainly raise a window where you can pick your save area:

Clicking OK will certainly remove the data to your selected location.

Supported Formats

In addition to GCF data, GCFScape likewise sustains Half-Life BSP, NCF, PAK, VPK, WAD, and also XZP data.At site freewindows10download.com from Our Articles


The complying with options are readily available inside the options food selection in GCFScape:


Enable verbose logging (made it possible for by default). Disable this alternative to minimize log outcome. This can be helpful when you are removing large amounts of files and also only wish to be educated of mistakes.

File Mapping

Enable Windows data mapping (enabled by default). File mapping is a reliable technique of random file gain access to. Some operating systems have problems with documents mapping (particularly Windows 98) and might generate errors; disable this alternative in such cases.

Quick File Mapping

Map the entire file to memory (as opposed to pieces of it as needed). Properly caches the data in memory. Can speed up points up if you have sufficient cost-free memory. Some running systems have problems with file mapping (specifically Windows 98) and also might generate errors; disable this alternative in such cases.

Unpredictable Accessibility

Enable unpredictable file gain access to (made it possible for by default). By default, Steam loads.gcf data in read/write setting and also is liable to transform their components any time (as updates take place). Should this occur, GCFScape would come to be unpredictable and also most likely crash. Unstable access permits you to open up GCF documents loaded in Heavy steam at your very own danger. It is typically secure and also can verify beneficial for analyzing which submits Steam is updating.

Compose Accessibility

Enable create documents access (impaired by default). Create access provides GCFScape the ability to change specific data and is not compatible with volatile accessibility for the instability a mix of the two would create. This option is needed for GCF defragmentation.


In version 1.5.0, GCFScape included the capacity to validate GCF documents. This procedure calculates a collection of crossbreed CRC 32 and Adler-32 checksums for each documents within a GCF documents and compares each checksum to the checksums precalculated and also kept within the GCF documents. This function supplies a fast alternative to Steam for checking GCF corruption and listing corrupt as well as incomplete files, but can not fix corrupted GCF data as Steam can.

To validate all or part of a GCF data making use of GCFScape, finish the complying with steps:

  1. Introduce GCFScape.
  2. From the Documents food selection, open your GCF data.
  3. Search to the top level folder you want to confirm (origin for the entire GCF data).
  4. Right click the folder and also select Validate.
  5. Repeat actions 2-4 for every GCF file you desire to validate.


In version 1.6.0, the capacity to defragment GCF files was included in GCFScape. This feature was added after several examinations by Nem showed that Steam'’ s built in defragmenter did not constantly completely defragment a video game'’ s GCF data. In fact, Steam would often wrongly report a fragmentation of 0% when truth fragmentation was as high or greater than 10%, a value incredibly destructive to performance.

GCFScape specifies the fragmentation proportion to be the variety of utilized collections that are out of order split by the complete variety of utilized collections. The initial collection in a file can never ever be out of order, so a data that includes only one collection (normally < <8192 B) can never be fragmented. At 10% fragmentation, a typical ~ 785 MEGABYTES GCF file (about 100,000 clusters at 8192 B per cluster) would require, usually, one seek operation for every 80 KB of data check out. You can check out the fragmentation of any type of data or folder (origin for the entire GCF data) by inspecting its residential or commercial properties.

To defragment your GCF documents making use of GCFScape, finish the following steps:

  1. Closure Heavy steam.
  2. Launch GCFScape.
  3. In the Options food selection, allow Write Accessibility and also disable Volatile Accessibility.
  4. From the Documents food selection, open your GCF data.
  5. From the Tools menu, pick Defragment.
  6. Repeat actions 4-5 for each GCF file you want to defragment.

Keep in mind: The defragmentation procedure is fairly slow-moving, however can be canceled and also returned to any time.

Running GCFScape

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

These requirements apply to all running systems, MacOS and also Linux customers will require to mount these in order to run GCFScape via White wine.
