decided to try this again after several years. Program would not extract a multi file split archive in the ZIP format that was created with Entropy, which for the record, Apple's built in Archiver utility, BetterZip and TheUnArchiver, plus the free 7Zip Windows utility, have NO trouble extracting the exact same file I tested with. This archive was an ISO image over 6GB, split into 200MB chunks for easier uploading.
In looking at the company website, it says " Can Archiver open split archives? Yes, Archiver can combine and then unarchive split archives in RAR and 7zip format." Note, only RAR and 7zip, not Zip listed.
Before someone chimes in and says " So What, 7z is better than Zip anyway"....I'm not here to debate the pros and cons of compression formats, this is not the place, but from a functionality view, the inability to handle split archives in ZIP format (arguably the most common format today) would seem to be a serious short coming for a program that has the sole purpose of handling archives.
For now, I'm sticking with Entropy on the Mac, and Pavlov's 7Zip utility on Windows. Don't get me wrong, I would like this program to work. Entropy hasn't been updated in two years, I'm worried it has been abandoned. I'm not particularly sold on the BetterZip UI and by it's own admission (look at the change log) BetterZip is still finding/fixing bugs that, in my opinion, should not be bugs in a program that has been around that long.
Honestly, when I want to be absolutely sure there is no problem (i.e. preparing an archive for work or to be shared), I fire up Windows in a virtual machine and use 7Zip by Pavlov.
