# 7-Zip Application: Igor Pavlov Also called 7zip, 7-zip, seven zip Igor Pavlov, System An archive tool. The window is 7zFM.exe. The command line is 7z.exe. One product, not seven software URLs. ## What you need to know 7-Zip is one product. Version SKUs do not each get a wiki URL. Igor Pavlov's 7-Zip packs zip, 7z, and many other formats. Download it from 7-zip.org. Ad-network "7zip pro" pages are the usual junk. - **What is it?**: An archive manager **Paid?**: The official build is free **Same as WinRAR?**: Different product Feex says If you need an unzipper, I would use the official 7-Zip and skip the toolbar bundle. High CPU during ultra compress is the setting, not a virus. ## What is 7-Zip? 7-Zip is an archive manager. 7zFM.exe is the file manager. 7z.exe is the CLI. Context-menu extracts often call 7zG.exe. ## If you have never used it If you downloaded a .zip or .7z and Windows will not open it the way you want, 7-Zip is a small free extractor. Get it from 7-zip.org only. After install, right-click the archive and choose 7-Zip. It is not WinRAR, not a toolbar, and not a Windows update. ## What is it used for? **Create and extract archives** Zip, 7z, tar, and many other containers from the 7-Zip File Manager. **7z and zip** 7z is the native format. Zip is what most people email. Same program. **Command-line batch compress** 7z.exe in scripts. High CPU on ultra is the compression setting, not malware. ## Who is it for? - People who want a small official unzipper - Users who compress with LZMA2 - Anyone who should ignore "7-Zip Pro" ads ## Current status Actively maintained by Igor Pavlov. Version numbers change. This article is the Windows desktop build, not a fork. ## How old is it? Igor Pavlov first released 7-Zip in 1999. It is an old, still-updated utility. The 7z format and LZMA came from this project. A "7-Zip Pro 2026" paid store listing is not the official build. ## Versions Major channels first. Exact build numbers are not all verified here. Stable Windows x64 ## System requirements Values follow the publisher's public guidance. Workload still changes the real need. ### Minimum | Operating system | Current Windows 10 or Windows 11, per the 7-Zip Windows build | | ---------------- | ------------------------------------------------------------------------ | | RAM | Dictionary size during compress is the limit, not a listed game-like GPU | ## Resource profile - **CPU demand**: High on ultra LZMA2, by design **RAM demand**: Follows dictionary size **Disk demand**: Source plus archive ## Installed processes These executables belong to this product when it is installed. | 7zFM.exe | File Manager | | -------- | ---------------------------- | | 7z.exe | Command line | | 7zG.exe | GUI helper for some extracts | ## Startup components 7-Zip should not start with Windows. A Startup entry is unexpected. ## File locations | Typical install | C:\Program Files\7-Zip\\ | | --------------- | ------------------------ | ## File formats 7z, ZIP, TAR, many others listed on 7-zip.org ## Common problems ### Defender scans the new archive MsMpEng can wake after a large write. That is the scanner. ### Fake download sites The official domain is 7-zip.org. ## Getting unstuck ### Download only from 7-zip.org Ad-network "7zip pro" pages bundle toolbars. The real installer is a small exe from Igor Pavlov's site. ### Associate archives in 7-Zip options if double-click opens the wrong app Tools > Options > System. That is a file association, not a Windows reinstall. ### Expect Defender to scan a new large archive MsMpEng can wake after you write a big 7z. That is the scanner. ## Alternatives Windows Explorer unzip covers simple zip. WinRAR is a different license. Pick them for format or habit, not a risk meter. ## Official help and downloads Start with the vendor. Random exe sites are not a support channel. | Official site / download | [www.7-zip.org/ ](https://www.7-zip.org/)The only download we recommend | | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------ | | FAQ | [www.7-zip.org/faq.html ](https://www.7-zip.org/faq.html)Formats and command line | | Source / history | [www.7-zip.org/history.txt ](https://www.7-zip.org/history.txt)Version history from the author | | SourceForge project | [sourceforge.net/projects/sevenzip/ ](https://sourceforge.net/projects/sevenzip/)Another official distribution path Pavlov documents | ## Related hardware More RAM helps huge dictionaries.
