FAQ
Reader questions

Will extracting a 7z file delete the original archive?
No, extracting creates a copy of the contents and leaves the original .7z file intact unless you manually delete it.

Yes, apps like Keka let you create 7z archives quickly by right-clicking a file or folder and choosing to compress it into 7z format.
