How do you add avast to pkzip?

The settings you quote are exactly those I tried with version 6, and it fails every time. My kludge only works with the virus check function, as I said, and not with the “extract to any directory”. I’ve written to PKware (I was going to say Phil Katz, but I bet he’s retired long ago :slight_smile: ) and asked what parameter is actually passed by v6, but I’m fairly sure from ashquick’s error message that it is passing it wrapped in quotes. You’re quite correct that PKZIP really shouldn’t extract to a directory containing files but, in their defence, it does warn you not to when you extract.

Anyway, I can’t afford to buy a new version of PKZIP (there aren’t enough new features to justify it, and no one I know can handle the higher compressions in v6, never mind v.8 - so I guess I’ll have to give up at that - or always extract to the same directory.

Galen, I really suggest you go to 7-Zip

I’ll have a look at 7ZIP - especially as you mentioned the magic word - FREE :slight_smile: I’ve never thought of changing, I’ve been using PKZIP since my Fidonet bulletin board days when Phil Katz first produced the Zip format and had his big legal patent battles with ARC - so I’ve sort of got used to it.

I’ve just had an email from PKWARE confirming that the %e parameter is passed wrapped in quotes in v6, so since your version 8 works just fine, I’ve written back to ask if they’ve changed the parameter that is passed.

Click on ‘Links’ in my signature and enjoy ;D

I did, and I will. Thank very much. I’ve bookmarked the page, and it will get some use, I’m sure.

It has - I just had a reply from PKware. Versions 6 and 8 are completely different, and version 8 doesn’t wrap the %e in quotes like version 6. Albeit that doesn’t solve my problem, at least it tells us that v6 and Avast! are incompatible, so I can stop trying and make do with what I’ve got.

I’ll try to do something about it.

It would be nice if you could, - but since my PKZIP is out of date anyway, don’t go to too much trouble.
