CHM files

Hey guys I notice the other day that when I updated my Microsoft -Html help file (.chm) that the update files were huge, I just figured, as I had made a lot of changes the patches would be large. Today I made just a single change to the help file for a TOC but it was the same. All the .wyu files are the same size as the catchall... Is it not able to patch a .chm file?

thanks

Yes, wyBuild can patch chm files (and any other files). So why are the files so large? Likely because the chm file format uses compression. In other words when you make even the smallest change in a chm the big blob of data will look almost completely different than the old big blob of data. This means the delta patches will be comparatively large.

ThanksI'm Using Adobe RoboHelp 8 and I see in the html compile it says optimize file size. So I would need to uncheck that box?

Thanks Guys

Unchecked the box and it made no difference. The test one was 20,677 for ver1the update from that test to ver2 was 20,629

It sounds like one was blob compressed and the other wasn't. You'll get the same result. Test 2 versions where the checkbox is unchecked for both versions.

Both were saved unchecked I was hoping the update would drop down to a fraction of the 20 but it didn't is the same for the exe I guess it gets compressed by my anti-piracy software so it is always within bytes of the same size all the time.
