reCAB.zip

Will this work for all Data1.cab proggies, like Acrobat Pro?

It's cool! It slimmed flash 8's data1.cab from 90mb to 72 mb. And works like a charm.

Hmm, noticed some apps has both a "data1.cab" and a "data2.cab".

If I temporarily rename the data2 cab to data1 and run this script, maybe that works to ?

(re-naming it back to 2 afterwards offcourse)

Ex. PowerDVD 6

Data2.cab is different...

Data2.cab is different...

Ok, that's a shame

In powerdvd6 the data1.cab ain't that large.

When I tried to execute the script, a "New" folder appeared, but there isn't any data1.cab in it ?

Maybe it doesn't work on this proggie....

Hell yes, is just an intermediate result obtained while trying to repack AcroPro 7.0.7

Notice the folowing line in the script:

SET cabinet=Data1.cab

I couldn't test every proggy out there, but I'll make a list with your findings, work or not.

I can't find data1.cab on my computer

You are not supposed to find it. You are supposed to use the scripts to recompress Data1.cab file in the application installer you want.

If you don't have an installer with data1.cab, don't use them.

What version of InstallShield support the recab?
