Posted: Sat Mar 15, 2014 3:53 pm
Hi! Does anybody know how to set up the compression level when using the packer library (UseZipPacker in my case...)?
Thanks!
Thanks!

Define file.s,packfile.s,extn.s,pack.i
file = OpenFileRequester("Choosefile","","*.*",1)
extn = GetExtensionPart(file)
packfile = Left(file,Len(file)-Len(extn)) + "zip"
pack = CreatePack(#PB_Any,packfile,#PB_PackerPlugin_Zip )
AddPackFile2(pack,file,packfile,9)
ClosePack(pack)

Thanks! Just what I needed. It's working also on snow leopard btwts-soft wrote:To store, without compressing, you can use this:Windows x86, x64 and Linux x64 only.Code: Select all
