Options
The following options are available inside the options menu in 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 (enabled 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.
Write Access
Enable write file access (disabled by default). Write access gives GCFScape the ability to modify certain files and is not compatible with volatile access for the instability a combination of the two would cause. This option is required for GCF defragmentation.
