What is it? 7-Zip Compressed File

Where’s it from? 7z is an open source compressed file standard developed by the 7-Zip Organization. It supports compression/decompression of 7z, ZIP, GZIP, BZIP2 and TAR compressed files. It also supports decompression-only of ARJ, CAB, CHM, CPIO, DEB, DMG, HFS, ISO, LZH, LZMA, MSI, NSIS, RAR, RPM, UDF, WIM, XAR and Z. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 percent better than the ratio provided by PKZip and WinZip.

How do I use it? Use the 7-Zip archiver utility downloaded from the link above.

Can I safely delete or move it? Yes.

Can it be dangerous? Yes. Any compressed file can contain malware. Use an antivirus program.

Do you mind if I quote a few of your articles as long as I provide credit and sources back to your website? My blog site is in the very same niche as yours and my users would really benefit from some of the information you present here. Please let me know if this okay with you. Cheers!

Wow! Thank you! I continuously needed to write on my site something like that. Can I implement a fragment of your post to my website?
