| Q. | |
| When I launch GCFScape I get the following error message: | |
| "The application failed to initialize properly (0xc0000135). Click ok | |
| to terminate the application." | |
| A. | |
| GCFScape is written in C++ .NET (using Visual C++ 2008 SP1) and as such | |
| requires the .NET 2.0 Framework and Visual C++ 2008 SP1 runtime to run. | |
| If you do not have the .Net Framework installed, are unsure what to do, | |
| or are having problems, please install the .Net 3.5 Framework which | |
| contains all the necessary runtimes: | |

| If you already have the .Net 2.0 Framework installed, then all you need | |
| is the updated C++ runtime. See the following links for more information: | |

| Q. | |
| Are GCF files compressed archives? | |
| A. | |
| No. | |
| Q. | |
| What are GCF files then? | |
| A. | |
| GCF (Assumed to stand for Game Cache File) files can best be compared to a | |
| virtual file system not unlike FAT or other common file systems. The virtual | |
| file system supports meta data, file fragments, checksums and other minor | |
| features. GCF files are the backbone of Steam's content delivery system. | |
| Q. | |
| Why do I have to close Steam to open a GCF file? | |
| A. | |
| GCFScape uses a technique called file mapping to directly access data in a | |
| GCF file as you would data in memory. This is a useful technique because it | |
| means GCFScape doesn't have to read tons of data into memory to read a GCF | |
| file and it can read a GCF file without having to seek all over the place. | |
| Because Steam opens GCF files in read/write mode and is liable to change the | |
| contents of any GCF file at any time, GCFScape requires that you close Steam. | |
| If Steam was open and it changed the contents of a GCF file while it was mapped, | |
| GCFScape would become unstable and likely crash. | |
| Q. | |
| When I open a package I get the following error message: | |
| "Failed to open file." | |
| A. | |
| GCFScape requires strict read rights to a package file to maintain stability. | |
| Make sure the package file is not open in any other program including Steam. | |
| As a work around you can enable Volatile Access from the Options menu. Note: | |
| this may cause GCFScape to become unstable if Steam is updating the package you | |
| have open. | |
| Q. | |
| When I open a GCF file I get the following error message: | |
| "Invalid GCF version number (vX)." | |
| A. | |
| GCFScape does not know how to read the GCF file version you are attempting to | |
| open. This could be because it is an old GCF file version that I haven't yet | |
| added support for (due to the fact that I don't know what the format is) or a | |
| new GCF file version that a recent Steam update produced. Either way let me know. | |
| Q. | |
| When I open a package I get the following error message: | |
| "Corrupt file." | |
| A. | |
| GCFScape will display this error when it maps a package file to memory only to | |
| find there is not enough data in the file for the resulting map. This may or may | |
| not mean your file is corrupt but almost certainly means GCFScape would crash it | |
| continued to load your package file. | |
| Q. | |
| When I open a package I get the following error message: | |
| "Failed to map view of file." | |
| A. | |
| GCFScape will display this error when the system call MapViewOfFile() fails. | |
| This can happen on older operating systems with primitive virtual memory management. | |
| As a work around you can disable File Mapping from the Options menu. Note: disabling | |
| File Mapping will incur a memory and performance penalty. | |
| Q. | |
| When I press the Extract button, a Browse for Folder dialog appears but there is | |
| no directory tree to allow me to select a folder. | |
| A. | |
| There is an unfortunate bug with the .NET framework that causes this dialog to | |
| operate incorrectly. This is a pretty rare occurrence, but there is a workaround: | |
| 1. Close GCFScape. | |
| 2. Open the gcfscape.cfg file, located in your GCFScape directory, in notepad. | |
| 3. Set the GCFScape.ExtractDirectory argument to a folder on your hard drive such as C:\. | |
| 4. Open GCFScape and extract your file. | |
| Q. | |
| When I extract a file I get the following error message: | |
| "Error writing [filename] (File contains no physical data to write)." | |
| A. | |
| This error occurs when you attempt to extract a file that has no physical data associated | |
| with it. This is a file that exists in the directory tree but which Steam has not yet | |
| downloaded. Use Steam to make sure the file is fully acquired. | |
| Q. | |
| How do I create a GCF file? | |
| A. | |
| As of yet, not enough is known about the GCF file format to programmatically create one. | |
| There are still plenty of unknown fields that need an understanding before a GCF file can | |
| be created. That said there is also no guarantee that creating a GCF file is all that is | |
| needed for Steam to recognize and make use of it. Some other registration might be required | |
| and may not be possible without hacking Steam. For these reasons I have no plans to add the | |
| ability to create a GCF file. | |
| Q. | |
| How do I modify a GCF file? | |
| A. | |
| The purpose of the GCF file is to make it easy for Steam to update Valve's software. | |
| When a new version of a program (say CS) is released, all Steam has to do is look in | |
| the CS GCF file and compare versions (hashes) of each file to determine if each file | |
| needs to be added, updated or removed. Because of this, if you were to modify a file, | |
| Steam would interpret this as meaning that the file is out of date and redownload | |
| the correct version of the file. | |
| Steam does, however, provide an interface to add or overwrite a file. To add or | |
| overwrite a file simply place it in the corresponding directory in the | |
| Steam\SteamApps\[EMail]\[GCF File] directory on your hard drive. You might have to | |
| create the appropriate subdirectories. | |
| Q. | |
| Will GCFScape be able to create or modify GCF files in the future? | |
| A. | |
| Not likely. | |
