Regarding GCFScape

GCFScape is a little device that can open and remove from GCF documents that are used by Vapor for video game material storage space. It can be downloaded and install.

GCFScape 1.7.1 or far better is called for to open VPK data. To search the base web content of a video game using VPK, you need to open the index file pak_01_dir. vpk.


Suggestion: When you set up GCFScape ensure you connect GCF documents with GCFScape so they'’ ll open straight away. The files will be offered icons if this has been done.

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

Clicking the little button, you can browse the folders clicking on them so they increase and show subfolders thus, after that clicking on a folder will show the contents to the right:

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

Clicking this will bring up a home window where you can select your conserve place:

Clicking OK will certainly draw out the documents to your selected area.follow the link what is gcfscape At our site

Supported Formats

Along with GCF documents, GCFScape also supports Half-Life BSP, NCF, PAK, VPK, WAD, as well as XZP data.


The following choices are available inside the choices food selection in GCFScape:


Enable verbose logging (enabled by default). Disable this choice to decrease log result. This can be helpful when you are drawing out large quantities of data and also just intend to be notified of mistakes.

Submit Mapping

Enable Windows documents mapping (enabled by default). File mapping is an effective approach of random documents access. Some running systems have problems with documents mapping (in particular Windows 98) as well as may generate errors; disable this alternative in such cases.

Quick File Mapping

Map the whole file to memory (rather than pieces of it as required). Properly caches the file in memory. Can speed up points up if you have sufficient complimentary memory. Some running systems have problems with data mapping (in particular Windows 98) and may create errors; disable this choice in such instances.

Unstable Gain access to

Enable unpredictable documents accessibility (enabled by default). By default, Heavy steam loads.gcf data in read/write setting and is liable to transform their contents at any moment (as updates occur). Must this occur, GCFScape would come to be unpredictable and also most likely accident. Unpredictable accessibility permits you to open up GCF documents loaded in Steam at your very own danger. It is usually secure as well as can verify helpful for checking out which submits Heavy steam is upgrading.

Create Access

Enable compose data gain access to (impaired by default). Compose access gives GCFScape the capacity to modify particular files as well as is not compatible with unstable accessibility for the instability a combination of the two would cause. This option is needed for GCF defragmentation.


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

To verify all or part of a GCF documents utilizing GCFScape, complete the following steps:

  1. Introduce GCFScape.
  2. From the Data menu, open your GCF data.
  3. Surf to the leading degree folder you want to validate (origin for the entire GCF documents).
  4. Right click on the folder and also pick Validate.
  5. Repeat actions 2-4 for each and every GCF documents you wish to validate.


In variation 1.6.0, the capacity to defragment GCF data was included in GCFScape. This feature was added after several tests by Nem indicated that Steam'’ s integrated in defragmenter did not always entirely defragment a video game'’ s GCF documents. As a matter of fact, Vapor would usually wrongly report a fragmentation of 0% when truth fragmentation was as high or more than 10%, a worth exceptionally harmful to efficiency.

GCFScape specifies the fragmentation ratio to be the number of used clusters that are out of order divided by the complete number of made use of clusters. The first collection in a data can never be out of order, so a documents that consists of just one cluster (normally < <8192 B) can never ever be fragmented. At 10% fragmentation, a common ~ 785 MEGABYTES GCF file (about 100,000 clusters at 8192 B per cluster) would call for, usually, one seek procedure for each 80 KB of information read. You can watch the fragmentation of any data or folder (root for the whole GCF file) by checking its properties.

To defragment your GCF documents utilizing GCFScape, finish the complying with actions:

  1. Shutdown Heavy steam.
  2. Introduce GCFScape.
  3. In the Options menu, enable Write Gain access to and also disable Volatile Access.
  4. From the Data food selection, open your GCF data.
  5. From the Tools menu, select Defragment.
  6. Repeat steps 4-5 for each GCF data you want to defragment.

Keep in mind: The defragmentation process is fairly slow, but can be canceled and also returned to any time.

Running GCFScape

GCFScape needs. INTERNET 4.0 (or later on), and Visual C++ 2010 Runtime (x86 or x64) to run.

These needs relate to all running systems, MacOS and Linux users will need to install these in order to run GCFScape through Wine.
