No other product on any other platform comes close to providing the range of functionality that Stuffit provides.

Most of the low-star reviews here approach this product as though it were simple compression-decompression software utility, ignoring the fact that Allume has a variety of options for compression:

If all you want to do is double click on things to decompress them, then use Allume's free decompresser, Stuffit Expander -- it works with just about every archive format.

If you just want to make the occasional archive, then save your money and buy Allume's Stuffit Standard Edition -- it handles the resource fork issue transparently and allows non-experts to make foolproof archives.

If you want to regularly interact with archives and actually manage them, then Allume's Stuffit Deluxe is the market leader by a long shot.
