Supported Formats

In addition to GCF documents, GCFScape also sustains Half-Life BSP, NCF, PAK, VPK, WAD, as well as XZP documents.


The following alternatives are offered inside the options food selection in GCFScape:


Enable verbose logging (allowed by default). Disable this alternative to lower log result. This can be valuable when you are drawing out big amounts of files as well as only want to be notified of errors.

File Mapping

Enable Windows data mapping (allowed by default). Submit mapping is a reliable technique of arbitrary file access. Some running systems have troubles with data mapping (particularly Windows 98) and might produce mistakes; disable this choice in such instances.

Map the entire file to memory (rather than items of it as required). Efficiently caches the documents in memory. Can speed up things up if you have enough cost-free memory. Some operating systems have issues with file mapping (in particular Windows 98) and might generate mistakes; disable this choice in such situations.

Unpredictable Accessibility

Enable unpredictable file gain access to (made it possible for by default).

It is typically steady and can verify helpful for checking out which files Heavy steam is upgrading.

Compose Accessibility

Enable create file gain access to (disabled by default). Create gain access to provides GCFScape the capacity to change certain documents and is not suitable with volatile accessibility for the instability a combination of both would cause. This option is required for GCF defragmentation.


In version 1.5.0, GCFScape added the capability to confirm GCF data. This procedure calculates a collection of crossbreed CRC 32 and also Adler-32 checksums for each and every documents within a GCF file and contrasts each checksum to the checksums precalculated and kept within the GCF file. This function supplies a fast option to Steam for inspecting GCF corruption as well as listing corrupt and incomplete data, yet can not repair damaged GCF data as Vapor can.

In version 1.6.0, the ability to defragment GCF documents was added to GCFScape. This attribute was included after several tests by Nem indicated that Vapor'’ s built in defragmenter did not constantly totally defragment a game'’ s GCF data. Actually, Heavy steam would certainly commonly incorrectly report a fragmentation of 0% when truth fragmentation was as high or greater than 10%, a worth very harmful to performance.

GCFScape specifies the fragmentation ratio to be the variety of used clusters that are out of order separated by the total variety of utilized clusters. The initial cluster in a documents can never ever be out of order, so a file that includes just one cluster (usually < <8192 B) can never ever be fragmented. At 10% fragmentation, a common ~ 785 MB GCF data (approximately 100,000 clusters at 8192 B per cluster) would certainly call for, on average, one look for operation for every 80 KB of data check out. You can check out the fragmentation of any type of documents or folder (origin for the whole GCF data) by examining its properties.
