Believe it or not, something can be too big. A monster truck can be difficult if not impossible to park. A retro-appeal boom box weighing down your shoulder may give you back problems. And all those files you don't want to delete are sucking up space on your hard drive. Up-and-comer
WinRAR 3.2 dukes it out with old-school champion
WinZip 8.1 for a shot at the title of best compression utility to help you squeeze down your extraneous files and lighten you up. And who couldn't use a little help getting rid of those excess pounds?
Interface
Both of our compression-utility heavyweights hit the mat with proven records, but champion WinZip has history and ring presence to spare. Both sport slightly cartoony icon-driven menus in their main interfaces, with challenger WinRAR's integrated file explorer racking a slight lead for ease of use. Defender WinZip tries to earn some usability points with features such as drag-and-drop file handling from Windows Explorer (also present in WinRAR) and an interface control that remembers whether you prefer to use the Wizard or Classic interface. Each program's zipping wizards earn points for easy archiving, with WinRAR pulling ahead by offering more compression options. But WinZip counterpunches with an integrated e-mail option and file management settings built in to the wizard.
Functionality
Though both WinZip and WinRAR are featherweights, at 4.11MB and 2.65MB respectively, slightly lighter WinRAR manages to pack more of a punch in basic compression, letting you choose from ZIP or slightly more efficient RAR archives for packing. The throw-down starts in the unpacking ring, with both supporting ARJ, CAB, GZ, LZH, TAR, UUE, and ZIP formats, and then mixing up the alphabet soup with slightly older formats such as ARC, B64, BHX, HQX, MIM, TAZ, TGZ, TZ, UU, XXE, and Z supported in the WinZip camp, and ACE, BZ2, JAR, ISO, and of course, RAR, supported by WinRAR. Both exhibit great speed in packing, but WinZip is the hands-down winner on this score, zipping up archives like nobody's business, compared with more lethargic WinRAR. Why pack at all? The savings in size of course, and that's where things in the match-up got interesting. For picture-heavy and layout files you won't see substantial differences in RAR and ZIP archives, but for text, music, and program files, RAR archives came in about 10 percent lighter, which in MBs adds up fast.
Features
Both WinZip and WinRAR bring features into the ring that will please even demanding archivists. Core functions are a right-click away from anywhere in Windows, and each can create self-extracting archives. For less demanding users, both contenders' wizards are speedy and flexible enough to keep you from diving into the full programs. WinZip boasts easy integration of virus scanning programs, sadly lacking in WinRAR. But WinRAR fights back with a data-recovery feature for damaged files, better file-naming options, and optional locking of archives to prevent accidental modifications. Our luchadores step it up for bigger files and file sets: WinRAR takes on WinZip's cumbersome but effective Span Disk archives for behemoth multidisk archiving with its easy-to-use RAR volumes. WinZip lands a decisive counterpunch with easy splitting of large-size archives for easier e-mailing.
Stability
Starting strong out of their corners, both WinRAR and WinZip install flawlessly and go where you tell them. As you would expect from an old pro with this many years in the ring, WinZip gets down to brass tacks with a no-fuss wizard-style installation that requires only minimal pointing and clicking before it's cracking its knuckles and ready to crunch files. WinRAR's equally muscular and customizable setup lets you control integration with windows, easily associating file types and controlling context menus, all with quick linkage to help for exploring your options. These fighters also quit the ring cleanly, packing complete uninstallers for when the fight is over.
Demo
Both of these heavyweight full-program demos behaved like real sportsmen, limiting their aggression to file packing and letting the trial period lapse without the programs becoming inoperable. WinZip is marginally more annoying on the demo score, employing the ugly splash screen each time the program sauntered into the ring throughout its 29-day trial period and beyond. Gentleman fighter WinRAR only made its more demure nag screen pitch after the bell rang on its 30-day run, taking the way of the samurai.
The winner
The judges are split, and no amount of behind-the-scenes cash exchange is going to fix it. Long-time title holder WinZip is the popular favorite for its lightening-fast reflexes, easy handling, and sheer ubiquity, but it won't be holding a championship belt above its head while it's staggering around the ring holding its cup from the compression-ratio blows delivered by up-and-comer WinRAR and its stable of newer archive formats.
