what does not found in block entries mean and when i run steam that pos corrupt file thing runs and when i try to paly cs in steam a black screen comes up and i have to restart my pos comp u know watsup

It means that the file exists in the directory for the GCF file but Steam hasn't yet downloaded it.

Hey how come u can't delete files in side GCF files is that gonna be inside the next GCFscape

Probably not.

GCF files are quite complex and while enough is known about them to be able to extract them there is not enough known to be able to modify them. This would probably require some documentation from Valve.

... hope this doesnt leave me sounding like an idiot... but...
i was killing some time today and i came across something that might peak your interest. I ran AnalogX's TextScan on steam.exe and among the long stream of nothingness that came out was a version number and copyright info ( here it is: deflate 1.1.4 Copyright 1995-2002 Jean-loup Gailly ). wondering what steam was doing with non-valve software i did a quick google search and this page poped up. interestingly, from what i gather zlib is a data compression library. While i neither have the time or the expertise to flush out its connection to steam, i was hopeing that it might become useful to your research on the .gcf format. good luck and keep up the great work nem.

Thanks for the info; I don't think that it has anything to do with the GCF files though because they aren't compressed, they are encrypted. (And yes, ZLIB is a well known decompression library.)

Major Possible bug.

Currently the hl2 "base source shared materials.gcf"is not being opened and comming up with an error for some people. (failed to map error)

i was getting the error untill i found out that my deskbar program "object dock".
http://www.stardock.com/products/objectdock/
was stoping gfc from opening while it was running
when i closed it it opened fine.

Possible bug?

hi nem firstly thanx for the program and i have a question for you(or other users if they know)i downloaded and ran your program.
i extracted the dod 1,3 into my hl directory.i entered the hl and clicked custom game.there was a dod bar.i clicked activate.but nothing happened. i cant activate it and hl shows its size 0mb but its almost 650mb.pls help me i want to play this game!!

you have to run DOD from the 'Play Games' menu in steam
(notice that one of the games is DOD)
you don't have to extract anything.

but i can't see the dod icon in play games section(i downloaded the stem with dod. There is a game cache file for dod in steamapps folder)

Maybe ask in the offical Steam forums?

Hey...

Uhm, nem. I have a question. It maybe just because im a newb, but I cant seem to get the program to run, nomatter what i do. I installed the ms NET framework as supposed, but when i launch GCFScape, i get these errors:

www.21padv.dk/pic/nin/1.jpg
www.21padv.dk/pic/nin/2.jpg

I have posted on the official forums to, but nobody seems to have an answer for me. So maybe you do... I have reinstalled MANY times now. But i do not know what i am doing wrong.

Plz, help me.....

hehe, ups. Sorry the first one is in danish. It says:

The procedure point strrchr was not found in the DLL-Library MSVCR71.dll

nin:
look at the second error. the title is '.NET initialization error'

that most likely means that you install of the .NET framework is corrupt or improperly installed.

go to Windows Update to get the most recent patch

scorp:
what Steam game package do you own?

Yep, it looks like a .net installation problem to me. You might want to scan your computer for viruses/adware to make sure nothing is interfering with it. Also, what version of the .net framework are you using?

Make sure you're using this redist of .NET

Also, if you have .NET 2.0 beta definately roll back to 1.1 as .NET has several problems with streamwriters and forced garbage collection ( although I do not know how often nem uses those features ).

Ok I am newby when it comes to this stuff because I know nothing about programing, not my area. I work with hardware, but anyhow I need some help, I was playing CSS online and some people in there were talking about how they had HL2 and blah blah blah. This got my attion because from what I understand is this game will not be relased untill NOV 16th. I talked to them and they said to use a prog called GCFScape and get the files out of steam. I did all of this and downloaded all of the files that I had to from here but I can not figuar out how to play HL2 now. Is that what this is for or am I just hopelessly lost?

Go away. we are not going to help you pirate HL2.

A lot of people seem to think GCFScape can somehow be used to crack Half-Life 2 so let me clear up these misconceptions. First off, Half-Life 2 preloads (and any other games you have not paid for or have not been released) and in encrypted form. To confirm this right click on a file and select its properties and GCFScape will happily tell you whether or not it is encrypted. GCFScape will extract these encrypted files, but they will be of no use to you. Secondly the Half-Life 2 preload does not contain all Half-Life 2 files, just bulky things like media, models and levels.

GCFScape was designed to allow legitimate developers to access files they need to develop with, nothing more.

Ok thanks. Sorry about that im not trying to pirate HL2, people were just talking about how they had it and I was like yeah I have the preload done too, but they were making it sound like they had it right now and they were playing it.

Where can i dowload the new version of GCFScape???

on the Download page listed under GCFScape in the side Navigation Bar.

Hey NEM, I'm part of a mod team, and you know what would be a supurb idea? A GCF Compiler. Thats right, I want to have the ability to create my own GCF files for the mod I'm currently working on. Do you think this is possible?

Regards,
PerfectH

P.S. I love GCFScape, your a genious for creating this :)

Read the FAQ

in addition, the only use of GCF files is to distrubute the media over Steam. Seeing as MOD devolpers can not yet distribute stuff on Steam, it is pointless.

And anyways, I do think that Steam supports PAK files, so you can use those insted.

when i start gcfscape, i get an error message:

The application failed to initialize properly (0xc0000135). Click Ok to terminate the application.

any ideas?

Make sure that you have the Microsoft .NET framework installed on your computer.

If you don't, you can get it through windows update or here:

And FYI, your problem is also explained in the GCFScape FAQ:
http://nemesis.thewavelength.net/index.php?p=34

I just downloaded GCFScape and i tried extracting all my files to another directory, all except the Source Materials extracted. if i try opening the Source Materials using GCFScape, it comes up with the error:
"Failed to map GCF file to memory." and it tells me to make sure that steam isnt running and its not. what am i doing wrong?

Try turning on 'volatile access' in the options menu.

i had to download the newest version but it worked and im able to extract the file now! thanks!

hi i click cs_compound.txt but i get an errroer message saying
Error writing C:\DOCUME~1\Owner\LOCALS~1\Temp\cs_compound.txt (File contains no physical data to write.)

See the FAQ.

I dunno rly how to use this, whenever i try to open sumin it comes up with errors like invalid file version

read the FAQ

why don't you use the dll's from the sdk, that whould make it possible to open the gcf's while steam is running!!!

You can open .gcf files when Steam is running, just enable the "Volatile Access" option from within the Options menu in GCFScape. The reason I don't use the Steam SDK is 1) the Steam SDK wasn't out when I first wrote the program, 2) the Steam file system interface isn't very flexible and 3) it adds additional dependencies; I hate having to install things to certain folders.

HI, i'm trying to install GCFScape and I keep getting this error:
"The setup files are corrupt. Please obtain a new copy of the program"

I've tried redownloading the installer several times, and I have already installed the .NET framework.

Any Ideas

I've double-checked the installer and it seems fine, perhaps there is an incompatibility problem with your system? Anyways, you don't need the installer to install GCFScape, there is also an "archive" (zip) distribution available, just unzip and run. The only difference is that it doesn't create shortcuts etc.

hi, i have a question. i need to decompile the map files from harf-life2. but there is no *.gcf file as i searched the whole hl2 folder. i can only find *.bsp files in the map folder. so do you mean that the bsp files are gcf files that need to be cracked before i use them in my program?

please check this out: http://www.geocities.com/cofrdrbob/faq.html

the faq says that:

Q. I can't find any of the Valve maps to decompile. Where are they?A. Probably stored in the .gcf file. You need GCF Scape to extract them, before they can be decompiled.


but what i get are bsp files, there is no gcf files.

In your ...\Steam\SteamApps\ folder there should be a half-life 2 content.gcf file. The file contains the HL2 .bsp files and you can open it with GCFScape to extract them.

Hi, i just downloaded every thing u need to run this program, but i keep getting this message....

how do i fix this.

plz help, tnx in advance dav3

GCFScape doesn't support HL2 .bsp files ... yet, try Rof's Pakrat.

ok, is there any way or any program to open up cutsom maps (other peoples maps) ??

if there is, and they work just as easyly as urs, could u tell me plz.

What do you mean open up custom maps? Which type (HL or HL2)?

i mean, i want to get the .vmf file from custom maps in css. like wot ur program does, but for custom maps instead of official maps.

or can ur program do custom maps aswell? if so.....how?

I tried usin urs, but i couldnt work it out....

v1.4.0 has Source BSP support, make sure to update the .NET framework if you install it.

pleeaaseeee

help copy CGF?????

as it programs copy Language???

I have Language in Portuguese... I guard language...

Hey dav3,
if you want to convert a .bsp-file into a .vmf file take a look at VMEX. It requires Java, but it doesn't extract any custom models and other custom staff (use GCFScape instead).
Hope I could help

Ok, I just got GCFScape, and I found all of textures that I wanted to extract for the terrain generator, but they aren't .wad... They are all either .vmt or.vtf. Is there something i have to do to change them to .wad, or what? Could someone please help this noob?

While I don't really recommend texturing Source terrains in TG, you can if you convert your .vtf files to .tga files then load the folder containing the .tga files in TG. This will allow TG to generate alphas as you paint the terrain which will be exported by TG. When you import your terrain into Hammer and apply a texture to it, the alphas should behave appropriately as long as the texturing scheme is one that the Source engine supports (e.g. three textures should never meet at one vertex).

Thanks much. But I just have 1 more question. How exactly do i convert the files from vmt or vtf to tga?

You may try my VTFEdit for that. There is a convert folder option in the Tools menu.

How can i edit a picture in a wad file?
with GCFScape appliction?
i download GCFScape and when edit a picture with GCFScape application & i save it but i don't sww the changes!
is this work for Counter Strike?
thank you

GCFScape can only view .wad files, not edit them. To Edit .wad files check out a program called Wally.

when i open the counter strike.gcf its gives the following error"invalid file:the file map is too small for its data blocks"

This error occurs when HLLib calculates that the .gcf file is not of sufficient size to hold all of the data that the header claims it does. In other words, your .gcf file may be truncated or otherwise corrupt. A quick check would be to look at its size. My counter-strike.gcf file is 265.11 MB, how big is yours?

If you believe this to be false and your .gcf file to be valid, please send it to me so I can take a closer look at it. It may be that I've fudged up the format somewhere.

hi nem
my counter strike.gcf file is 358.4mb

then how to get rid of this problem

Weird how yours would be a full ~100 MB bigger than mine when mine is fully up to date. At any rate, I'd have to inspect your .gcf file in person to figure out what's wrong with it. Any chance you have the facilities to get it to me?

GCFSpace is really nice for HL2, great work.

Just got Dark Messiah and thought "Hey its source .. lets open it."

But that didnt went very well at all. "Invalid VBSP (v262164).."

Is there any chans GCFSpace will get support for that ver.?

I can't add support for it if I don't know about it and I can't test it. If you can send me one of your .bsp files to ryansgregg@hotmail.com I'll take a look at the .bsp and see if it makes sense to add support.
