Questions about catalog (.clg) files.

[johnhc]

When I defined my install.wim file to Windows SIM, it said my catalog (.clg) file was out of date. The image has been modified. When I pointed to a folder with unmodified .wim, I go no such message. I did some research on the the catalog file and found that it is typically much smaller than the .wim file (<1 MB vs > 2 GB). Is it really important to update (re-create) the .clg file? The research seemed to indicate it contains information about the .wim file. What code uses this information? What are the problems if it is out of date? Is WSIM the only way to get a new one created? Is there a command line interface to do the creation if it is really necessary? Thanks, John.

No it is not so important, I usually delete all the files of sources folder except for Install.wim, boot.wim and setup.exe. Only these 3 files are important. I tried by myself and I am using my OS without any problem.

You dont have to rebuild it...but if you do update the file it will make visible in WSIM any of the NEW updates/features that you may have integrated subsequently into your wim, you can then use it to disable them with your unattended.xml

Thanks for all your replies. I think the idea of seeing things I have injected has some value, so will allow WSIM to create the .clg file - thanks ricktendo64. Enjoy, John.

Not on Windows 7 you don't.

While I agree that the .clg is useless, you cannot delete the entire sources folder like before with Vista. Microsoft changed something with 7 and now the boot.wim looks for certain files in the sources folder or the install drops dead.

But to re-iterate, the .clg is not a problem. Nothing to worry about (unless you just hate that error).

Ofcourse we can in windows 7 as well. I did and my OS working fine believe me or not..................

Here also, just done VM and wiped every file out of sources besides the 2 .wim and setup.exe and bmp. I left the other folders this time.

We can remove bmp file as well. I have already tried.

I modify those to change setup screens though. I inject into boot.wim 2 so may be ok but have to see.

I have also modified that image, still I see the modified image during the installation. I guess it takes the image from imageres.dll when we remove .bmp from sources folder. I guess if we changed the image in imageres.dll then we can removed that bmp as well.

Quite possibly. Now on to the meat of this. What folders have you sucessfully removed? Looking through setupact.log I know it uses some of those.

For some we need to remember that removing some stuff will fail depending on type of setup you are doing.

[nice_guy75]

I have only removed all the files of sources leaving 2 wims and setup.exe, that is it. Have you removed anything else apart from sources folder, I am trying to make my OS as lite as I can.

Thinking we need a "tested" safe removals list of the Sources folder?

Yes, I would also like to know what files I can delete from my DVD that are useless...did it with Vista and now disappointed that Windows 7 will not let me

And not only Sources folder but the other ones as well

At a bare minimum, you need to keep the DVD\Boot folder, and the DVD\EFI folder as well as the DVD\bootmgr file. I was able to safely remove the DVD\Support and DVD\Upgrade folders and still complete my installation. I also deleted the setup.exe from the root of the DVD.

Not sure why it didn't work for me when I tried deleting everything but the WIM's, so maybe that was just a fluke. nice_guy_75 is pretty adamant that it can be done, so maybe later I will pull out my clean DVD and try that on an untouched source. My only test of this failed on a heavily vLite'd image - way back in November.

@nice_guy_75, do you confirm that you are not using the vista boot.wim. My assumption (apparently wrong) was that the new boot.wim was doing something with one of the sub-folders of DVD\Sources, but if you are using the 7 boot.wim, and it works, so much for that theory.
