CLS-DiskSpan (UltraARC replacement)

[vollachr]

OK, question, does diskspan have an option to exclude files from the compression?

Because the built in exclude option of freearc doesn't seems to work with it, it crashes arc.exe.

Yes, it wasn't diskspan itself, that was my problem, the exclude option.

Consider diskspan as a compressor, answer this question so you have answer to the question you have asked me. Does pzlib for example have an option to exclude certain files?

So I guess that's a no... Well, but since it should be not different than any other compressors used with freearc (like srep, precomp, etc.), then why does the -x switch (exclude switch) for arc.exe causes a crash with diskspan when it doesn't with other external compressors?

Try to modify your simple Batch Codes, to reach the target, there is a solution to every problem, not persist the your job only on the external components you use.

In theory you're right, but I honestly changed the command and switches so many times in so many ways that I lost count, nothing helped.

Beside, the last thing you can say about my batch code is simple, it's huge & complex, taking multiple variables from external .ini files.

So far, the only command with diskspan that actually worked was using the one from the example provided with diskspan, almost to the letter.

So, for the time being I've just created a bypass that takes files that needs to be excluded and just moves them away from the source folder before compression and back after compression.

Again, this is only with Diskspan.

[vollachr]

Why do I get a popup message asking for the location of GameFolderName.002 during compression with CLS-Diskspan?

In my case specifically it was "Wasteland 2 Director's Cut.002"

Of course, there's no such file...

The specific compression method in said case was this:

srep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8

Diskspan sizes was DVD5 (4467mb:4474mb)

My command uses lots of information taken from variables, many of them are read from INI files, anyway, translating it to the actual command (approximately) it would look like this:

arc.exe a -ep1 -r -ed -s; -w"MyFolder\TempFiles" -msrep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8+diskspan:4467mb:4474mb "MyFolder\WL2_2xDVD5\Data.bin.001" "*" "-xUnins*" -dp"I:\Games\Wasteland 2 Director's Cut"

It compressed fine until it got to the point it need to create the .002 file, any help will be appreciated.

Of course I'm still trying to figure it out myself but if anyone could provide an explanation to the problem it'll help.

Thanks.

UPDATE:

Might have solved it by moving the exclude switch to be before the archive path (after the method), like this:

arc.exe a -ep1 -r -ed -s; -w"MyFolder\TempFiles" -msrep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8+diskspan:4467mb:4474mb "-xUnins*" "MyFolder\WL2_2xDVD5\Data.bin.001" "*" -dp"I:\Games\Wasteland 2 Director's Cut"

Still testing but it looks promising.

UPDATE 2:

Nope, it ends correctly but it doesn't exclude the files in the exclude switch.

I also have a problem with errorlevel check after using the arc.exe --sort command, from some reason it sets the errorlevel as 2 (two), which causes a problem with a following check in my batch script.

Arc.exe also shows an error unknown command when using the --sort command, it still sorts the file thought but as I said, set the errorlevel as 2 (two) which is a problem for me at the moment.

I'll update again when I know more.

UPDATE 3:

OK, I believe it finally working....

The correct command was this:

arc.exe a -ep1 -r -ed -s; -w"MyFolder\TempFiles" -dp"I:\Games\Wasteland 2 Director's Cut" "-xUnins*" -msrep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8+diskspan:4467mb:4474mb "MyFolder\WL2_2xDVD5\Data.bin.001" "*"

As for the errorlevel problem, I just changed the code the test for it a little and it now seems to work correctly.

I'll leave it all here in case someone else need to know the correct syntax to make Diskspan work with the exclude (-x & -x@) and the -dp switches.

[Th3Raven]

First of all thank you for this great tool and second, i think i managed to integrate it into Windows Phone Installer (FMX). I will post the results after some extensive tests currently doing.

ok so implementation seems is ok, but will do more tests to make sure.

Anyway anyone can help me modify this DLL to show like "filename-*.bin" = where * is a number "filename-1.bin; filename-2.bin; etc." Total noob in Delphi here

@Simorq

i think razor also added src ,so open the delphi file and add 64bit suport
and compile it

[Midnights]

Hi, after trying this, in my case is more easy to use, can you please add support for DiskSpan to this script please?
I have trying but dont know where to split/add code from the exemple in the archive, many thanks if you can help...

What's the issue with the script that comes with DiskSpan?

This script is the only one i have find able to select archives as a components, so you can add the game and extra stuff as optionnal, all that in arc format...

But for now, all the scripts i find for UltraArc dont have this option, so we need to use all the bin/arc... i need to use as a component...
I have try to add UltraArc R5 support to this script with no succes, so i look for DiskSpan now.

I not able to do something with big code like that is too much for me... i you can help me with that is gonna be awsome, UltraArc is very nice, user friendly...

DiskSpan is another option...

[zirkhaki]

I have one question, as I know diskspan does not support something like Mask method (different compression method for different file types). But is it possible to categorize all file into different folders (e.g. movies, zlib supported file, srep+lzma supprting files) and use Diskspan on these folders separately and finally put the *.bin files beside each other and edit record.ini so that the installer could extract them?

[KaktoR]

Yes, that's what I do for some conversions lately

[zirkhaki]

Do you mean you are doing the conversion separately or you've changed the script and it does all the things for you? If you're changing the Diskspan script for each game is it possible to tell me how I can do that? is it complicated? or is there a tutorial for that?

[KaktoR]

I use my own script which works with list files in which you have to write files by names or extensions and what method is used for a list file.

Unfortunatelly there is no real tutorial about that. But if you know a bit about batch it's very easy if you understand it once.
