I am out of ideas what I should do, I only can guess the problem is with 7zip somewhere. VeraCrypt - Disk encryption with strong security based on TrueCrypt. 7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard. Example: Folder with 'lot' of redundant DLL files: source: 500MB archive.7z compressed with 7-zip, 'Ultra' compression level: 58MB archive. When comparing PeaZip and 7z you can also consider the following projects: NanaZip - The 7-Zip derivative intended for the modern Windows experience. My file systen is ext4, I tried to copy the files to a different hdd also on ext4 and another one with ntfs, no change. Surprisingly, 7zip archives created with PeaZip have better compression ratio than archives created with 7zip original software. From 11 files I try to compress, it succeeded with 6, it didn't succeed with 5. The compression will succeed with other files, but not with all. It doesn't crash if I use compressor to create *.pea, which I don't want to use. Out-of-the-box, PeaZip is slower than better optimized apps as WinRar and Gnome Archive Manager, due to a time-consuming full archive pre-parsing stage meant to detect issues and provide information about the archive. But on the other hand I think zip compression is also done by 7z.Ĭompression ratio is not relevant, it will crash even of store. 7-Zip is the fastest application to open / browse large archives in all tests. It is available on Linux as either a Qt5 or GTK2 app, and it even has a portable. This is why I guess the problem lies in 7z, but I don't actually know for sure, because if I use peazip and try to compress the file to a single volume *.zip, it will also crash. 197K subscribers PeaZip is a free and open source archive manager that is cross-platform (Windows, Mac and Linux). usr/lib/peazip/res/7z/7z a -t7z -m0=LZMA -mmt=on -mx5 -md=16m -mfb=32 -ms=2g -v4699324416 -w '/home/xxx/xxx/file.7z' '/home/xxx/xxx/file.iso'Īrk compressor also crashes when trying to compress this file, and so is fileroller. The code which will succeed with split file is: P7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,4 CPUs) But if I choose single volume, it will give me this error:ħ-Zip 9.20 Copyright (c) 1999-2010 Igor Pavlov 7-Zip and PeaZip (which uses the same optimized Deflate algorithm of7-Zip) attains good compression in zip format with 97,70MB atintermediate speed, whileWinRar and Bandizip reach the lowest compression at 100MB and 101 MBrespectively, but with significantly higher compression speed. If I choose split the file to 1DVD size, it will succeed with a *.7z.001, this is why I know the compressed size. It has a size of 4.4GB and after compression it got about 3,8GB. I like to compress a file with 7zip, which doesn't succeed.
