The dictionary size of 1536m became available in 7-zip 15.05 beta () and since this is the first 15.x version mentioned in history.txt, then any product based on 7zxa.dll 15.x and later should handle such archives correctly.Īctually any product with LZMA2 support and which happen to successfully allocate large memory blocks should handle such archives correctly. WinRar known for its emphasis towards security and stability for many years and I can't believe that loss of data during 7z extraction have gone unnoticed and unfixed.īut there is one thing that must be noted.Īctually WinRar handles 7z archives via native 7zxa.dll which is the part of 7-zip Extra package.Īrchives you provided are simple 7z archives with LZMA2:1536m and 2 solid blocks. It was a good investment at the time, and I see no reason to change to a "free" option when paid version is working fine.ĪSUS ROG Strix Z690-A Gaming WiFi D4 / X99S GAMING 7ĬM MasterLiquid M元60 Mirror ARGB Close-Loop AIO / CORSAIR Hydro Series H100i ExtremeĬORSAIR Vengeance LPX 32GB (2 x 16GB) DDR4 3600 / G.Skill DDR4 2800 16GB 4x4GBĪSUS TUF Gaming GeForce RTX 4070 Ti / ASUS TUF Gaming GeForce RTX 3070 V2 OC EditionĤx Samsung 980 Pro 1TB M.2, 2x Crucial 1TB SSD / Samsung 870 PRO 500GB M.Birdie is right and I also think that such claims about WinRar's potential problems are nothing more than crap. Those who do generally just click on the "next" button, and never have to pay for it (but they do have to click through the "please pay" menu). Once you've done all of the install, most people don't even bring up the winrar program. I keep the latest 30 day trial around for installs. No problems means no reason to switch programs.Īs far as paying, I have a paid version on my media server and gaming rig. I've since upgraded to 圆4 winrar, and haven't seen any problems. The caveat is the testing was done about 3 years ago, using x86 versions of each program. My experience with 7-zip is that any highly compressed archive makes previewing the files impossible, and the decompression itself generally takes longer (I've run Winrar and 7-zip in parallel and 7-zip took 10-30% longer). ![]() Winrar deals with them without an issue, and even lets me preview them without a problem. Most of the files I deal with are a few hundred MB to a couple of GB. It is a bit quirky sometimes since it's a front end for various archivers. It has a nice interface, supports tons of archives and it's also free. Just ramp up the word size parameter and you'll gain quite some better compression rate while keeping the ZIP compatibility. Oh and 7-zip allows you to create higher compression rate standard ZIP archives. LZMA2 is fast and has great results.Īlso, as a side note, RAR5 format is now also using a derivate of LZ77 compression (basically LZMA), meaning it'll have roughly the same compression, usually a bit worse than LZMA2 in 7-zip. Just not worth the crazy waiting time for such tiny benefits. Most other archivers take 50x longer (at rates like few hundred KB/s) and only gain 1-2MB better compression with several gigabytes of data. In my case even beyond 20MB/s which is lightning fast. ![]() It can use as many CPU cores as you can offer to the program, meaning it'll provide amazing output rate. It's free, simple, no bloat or nags and has superb compression.
