I just couldn’t find what settings would give me the best results (there was no time to manually check all millions of combinations) and just continued to use Winrar which, by the way, i’ve even paid for. Some years ago when i moved my backups online where size was important for storage costs and bandwidth, i’ve actually tried 7z and gave up. Archiving options? “Create solid archive” for better compression, everything else as needed. Compression? “Store” for already compressed, “Best” for anything else.

Now Winrar: Archive format? RAR4 for compatibility, RAR for everything else. Word size? Solid Block size? No idea, never heard of. Dictionary size? Bigger is better, i guess. Compression method? No idea, let’s keep LZMA2 since it’s default. Compression level? Ok, bigger is better, lower for already compressed file types. Let’s compare 7-Zip’s and Winrar’s “Add to archive” windows the first just looks convoluted with throwing a million settings into your face that are explained just on obscure websites with datasheets while Winrar shows the essential ones in its “General” tab and everything else that 99% of users don’t need in other tabs.ħ-Zip: Archive format? Understandable. Most of us don’t complain because of mspaint-grade Win 3.11 icons, but about the whole user experience.

Now You: which archive software do you use, and P.: Winrar has a similar simple and effective interface and i’ve never heard anyone say anything.

Interested users can check out the full changelog here.

Add to Archive window supports setting a memory usage limit.

The program may also check the file to verify files.

7-Zip may create the text file file.sha256, which contains all file names and SHA-256 checksums.

The number of working CPU threads is removed for compression if the RAM size is not enough for compression operations with large LZMA2 dictionaries.

7-Zip writes an additional field for the filename in UTF-8 encoding in ZIP archives.

Decompression speed of LZMA and LZMA2 archives in ARM64 versions for Mac OS and Linux improved by 20-60%.

Maximum dictionary size for LZMA/LZMA2 compression operations was increased to 4 Gigabytes.

ARM64 version speed improvements for AES, CRC-32, SHA-1 and SHA-256.

The -ssp command line switches prevents that the system modifies the "last access time" property of source files for archiving and hashing operations.Default number of LZMA2 chunks per solid blocks increased in 7z archives, which improves the compression speed for large 7z archives on devices with a large number of CPU cores and threads.Improved compression ratio for fast and fastest compression levels.

ZIP AES encryption and 7z, RAR and ZIP AES decryption improved.

7-Zip supports new hardware instructions for SHA-1 and SHA-256 which new AMD Ryzen and Intel CPU's support this improves the performance of certain operations, including encrypting and decrypting ZIP AES, hash value calculations, and the speed of key derivation for encryption and decryption in 7z, ZIP and RAR archives.

Support for unpacking b64 files (Base64 encoding).

Contents is just a txt file with the text of this post.Here is the list of important changes when compared to the last stable version, 7-Zip 19.00:

With 64 MB dictionary and 16 threads will use up to 5 GB of ram to compress your archives, but 4-8 compression threads and up to 8 MB dictionary is more common, so memory usage will be less (up to ~1 GB of memory)Įdit: attached is a zip file compressed with PPMd algorithm. WinRAR defaults to maximum 4 MB dictionary I think, I'm not sure. The 7zip format of 7zip is much better than ZIP and even RAR in some cases, and you can use very big dictionaries and can use a lot of threads (for example with 16 threads and 1.5 GB dictionary, 7zip could use up to 145 GB of RAM to compress something, if you want absolutely the maximum compression on huge amount of data, like GBs of content) but that's ridiculous extremes. WinRar lets you choose between using the older RAR algorithms (until version 5) and newer algorithms which are not compatible with older rar decompressors. It's like the same story with RAR archives. the built in zip thing in Windows 7 opens the archive and shows the files in it, but can't extract a file compressed using the non-default algorithm PPMd (which is very very good at compressing text files or files with lots of words like html pages), the extraction fails with an error. simply choose from the compression method BZip2 or LZMA or PPMd

7zip supports those and also allows you to create such zip archives. WinZIP implemented several compression methods in ZIP files that are not using the standard DEFLATE algorithm.

I'm not even sure it opens all non-standard zip files.
