When using Windows, it is best to use Unzip One to open 7z files. However, as with any file, you should only open 7z files from trusted sources because there is always the possibility that a 7z file could be malicious. They are no less safe than any other similar file formats.

This is especially helpful when transferring or downloading larger files or folders. One benefit of using the 7z format is that it can be used with files that you want to split into several smaller parts. The 7z format is newer than the ZIP file format and it provides a high level of compression. 7z file extension is a compressed/archived file. Whatever the case, if you want to learn what it is and how to open it up and access the files within, you’re in the right place!

Maybe you’ve downloaded one of these files from the internet, or perhaps a colleague has sent you one via email. You may have also encountered 7z files - which are specific to the popular compression tool, 7-Zip. You’ve almost certainly come across archive formats like ZIP and RAR when downloading and sharing files.
