Ladik's MPQ Editor

[Luashine]

@Wiimeiser see Revisions in MPQ (file format) - HandWiki
2GB/4GB is sort of a natural barrier for 32-bit era software.

 

[Wiimeiser]

The limit should be 4GB though, not 2GB. Unless something is up with the format. Still no mention of max filesize on the linked Wiki page.

So it's up to Blizzard to fix the issue, then. Otherwise I guess I'd better start figuring out how to convert mdx files to m3...

Version 2 added an extended header to the format which contained data for an extended block table to allow for larger archive sizes.

Alternatively
(blocks VPN) MPQ Archives - MPQ file format search for "size", DWORD = 32-bit, as well as block size * type. It's not in clear text.

 

[Wiimeiser]

I can't seem to find what you're saying. Could you please translate it for me?

Also, all I can find online about 32-bit file size limits is that it's 4GB, but 2GB for a file containing a data model?

EDIT: I found this, so I guess the data is signed?

 

[Luashine]

Yes. 2^31 is 2 GiB, one bit taken by the sign of the number. I meant to include this link in the previous answer: Large-file support - Wikipedia
As Ladik's own documentation suggests, Warcraft 3 MPQs are Version 1 and thus it will abide by the rules which the original game expects. In this case the 2GiB limit.
If your resources don't fit in this size, you'll have to place them outside the map MPQ, inside the game folder and "Allow Local Files".

Is needed if you want to make your own units, sound, assets...

Not really an MPQ Editor issue directly, but more likely your map. It's either protected or not compatible with the specific versions of Warcraft 3.
For the first case, there are several ways to deprotect the map, but it requires a time consuming and sometimes, you'll most likely caught by errors during the process.
For the second case, it's pretty obvious because when you save a map using Reforged World Editor, it will add an exclusive features that were only present in Reforged, meaning you can no longer open it with the older ones. This thread might be helpful for solving this issue.

yay I've found the solution
just adding war3mapUnits.doo, but I have a question,
some of the MPQs have set as "read-only" which will unable to be edited and renewed. Besides of extracting files and create new evaluation copy version, is there another way to solve this problem?

 

[Luashine]

Some MPQs are opened in read-only mode because MPQ Editor does not try to repair all the brokenness that results from "protecting" the map archive. It is safer to not write to this MPQ and that's why it's in "read-only".
However if you are willing to invest a couple thousand euros for someone to work on MPQ repair, I'm sure you will find someone from the community or a freelancer to do this work

hi guys, it's me again
I loaded a map and it said "an attempt was made to load a program with an incorrect format"
does this mean the map I try to open was corrupted?
and do you guys know how to fix? I'll appreciate your help

Which patch of the game you have?

 

[GAcrewkent]

Which patch of the game you have?

1.26a

 

[Deleted member 238881]

1.26a

Then you're on classic. If - by any chance - you're trying to load map, which is created for patch above which has significant changes, that would be the case I suppose.

Hey, a question, one of these that seem so elementary that obviously someone's solved them:
I uploaded some files into the MPQ campaign file. Does this editor provide any way to automatically update war3campaign.imp file so that my new files are visible in imports tab? If not, is there any other tool that does that?

 

[Luashine]

The .imp file is only for metadata of the World Editor and management. The game doesn't need it. I am not aware of any tools.

 

[Macielos]

Yeah, but I will be working on my imported files in WE, so I'm gonna need them visible in import tab. Mass adding stuff to MPQ is pretty common thing to do by modders, so I thought someone has thought of a way to automate it. Because what's the alternative, other then importing the files via editor and manually setting their paths? Seems like building a house with stone hammer.

I guess I'll write my own tool then .

 

[Luashine]

You can check if HiveWE has better import file management?

 

[Macielos]

Okay, I ended up expanding my old script to be able to add content of a directory to an existing .imp file. Working like a charm.
