"Third party"
if 7zip is third party (of course it is but i assume every Johanna and Henry uses it).
The rest is "FFED3D party" which is a rather a loose Family.
7zip is to find here
and pardon me i don't like to be offending but it's really on everybody's machine or it should be.
It has a couple of advantages over .zip apart from a slightly higher compression, .zip is almost like a simple folder every bot can browse through it easy.
(just as easy as Windows or any OS can search for a file or even for a given string in a file residing in a .zip. An practical example; if i upload a zip in my cloud anyone can inspect the content even if he has only the rights to view the file, not so for a 7zip, here the cloud will argue that it cam't open it to inspect the content).
While of course it won't be total safe without encrypting but even in this it is out raking, it can even encrypt the header so it won't be possible to see only the file structure in it.
The software 7zip also can open images like ISO images or other disk images and handles every common compression format which exists.
I don't have to advertise for it, but with 7zip you won't need any else software to handle compressed folders and many images.
The possibility to inspect and extract a disk image without to mount it is a big advantage if you guess.
But read what they say about their program:
and perhaps this:
en.wikipedia.org
Personally i use 7zip almost since i use IBM PC's (i was a long time Amiga user up to 1998, 7zip was first published in 2000, but i really guess i use it exactly since then).
And in my personal opinion it belongs on every computer (so much that i ask myself how to live without it, at least i can't imagine it).
It is the first software i install after setting up a new OS because how else can i open all the 7zip compressed stuff i like to have.
You can also inspect and extract some installers, in other terms in certain cases you can extract from such an installer exactly and only a single file.
In short terms: 7zip is the swiss army knife of compression/decompression utilities, it just can't make coffee or cook pancakes (unfortunately).
One of the few drawbacks is that it has no error protection (which is almost obsolete since we don't use magnetic storage like floppies anymore) and based on my experience it can corrupt a file, but this happened to me only with pcm wave files (which didn't makes much sense FLAC offers a higher compression ratio for audio so it's at hand to use FLAC and store it in a uncompressed .zip archive, or alternatively store it in a .zip or .tar and compress the stream with 7zip if you need to compress a .wav at all i.e. to stream it to/from the web). It won't be the choice to exchange projects since it can fail in reproducing the file structure (honestly this never happened to me, but only the slightest possibility could mean a big loss of work here) that's why such is usually a simple .zip or a tarball. Due to the missing error protection it can't recover damaged data.
