Unlike the common compressed archive files such as ZIP and RAR, 7z files are a lot more secure. For starters, email providers cannot easily open this file format. Equally, it is straightforward to use, thanks to its user-friendly interface.
First, download and install the 7-Zip tool on your computer. Next, move to the file you need to open and right-click on it. Doing this gives you a submenu where you can select the 7-zip option and navigate to the 'Open Archive' option.
It's possible that new version of 7-Zip can solve your problems with 7z archives.So download latest version of 7-Zip and try to use that new version.You can try also latest alpha or beta version.If new version also doesn't help, read this manual.
There are some possible cases when archive is corrupted: You can open archive and you can see the list of files, but when you press Extract or Test command, there are some errors: Data Error or CRC Error. When you open archive, you get message "Can not open file 'a.7z' as archive"Corruption case: Data errors or CRC errors for files inside archiveHere we describe the case, when you can open archive and you see the list of files, but when you press Extract or Test command, there are some errors: Data Error or CRC Error.
For example, if you have multi-volume archive: a.7z.001, ... , a.7z.009, but one part a.7z.008 is missing,just copy a.7z.007 to file a.7z.008, and 7-Zip will see correct size of archive.Or if some part was reduced, look the size of another parts and restore original (correct) size of "bad" part, so total size will be correct again, and 7-zip will be able to open headers.
We have two parts: a.7z.001 (3000 bytes) and a.7z.002 (740 bytes).Then we copy a.7z.001 to bad.7z and try to open bad.7z. And we getthe message "Can not open file 'bad.7z' as archive", so we have corrupted archive.
Although 7Zip download is free, some may think that it will work poorly or 7Zip may not be safe. As a matter of fact, 7Zip is more than a free tool that can deliver the highest compression among others. There is more than what meets the eye.

Now that The UnArchiver has been installed and associated with .7z 7-zip files, you can then just launch a .7z archive by double-clicking on it, and it will open within the UnArchiver utility, decompressing in the same location of the original 7z file and then automatically exiting the application when finished. You can also open The Unarchiver directly, and then open the file through Unarchiver directly, where it will extract as well.

7Z is the file extension used for an archived file created using 7-Zip, a free, open-source file compression tool. 7Z is similar to other archived formats, such as ZIP, TAR.GZ, RAR, and ISO, but uses a higher compression ratio, along with AES-256 encryption.
When deciding which free WinZip alternative to download and use, first consider what your actual needs are, as sometimes free platforms may only provide basic options, so if you need to use advanced tools you may find a paid platform is much more worthwhile. Additionally, free and budget software options can sometimes prove limited when it comes to the variety of tools available, while higher-end software can really cater for every need, so do ensure you have a good idea of which compression and zip features you think you may require.
To test for the best free WinZip alternative we first set up an account with the relevant software platform, whether as a download or as an online service. We then tested the service to see how the software could be used for different purposes and in different situations. The aim was to push each WinZip alternative to see how useful its basic tools were and also how easy it was to get to grips with any more advanced tools.
WinZip (opens in new tab) is the best-known software for creating and opening compressed file archives, but it's not the only option and there are many superb free alternatives worth investigating before you open your wallet.
Many of the options shown on the main splash screen are links to paid applications like dedicated encryption and decryption tools, but don't let this put you off; all the essentials that you'll find in other free file compression software are present and correct, including archive creation, extraction, repair, and multi-volume ZIP writing. 2ff7e9595c
