Do you use WinRAR, WinZip, or 7Zip

[Admiral Naismith]

Most of the comments say 7zip.. The poll shows winRAR being the leading....

 

Suspicious...

 

I sometimes feel sorry for winRAR, because I've fewer people have bought winRAR than have been on the Moon.

WinRAR quite often has been picked up as malicious by Avast, AVG and Avira on my computers, so I personally don't trust it that much.

It actually has quite a few different types of compression methods for zip files.

 

 

I have to agree with that, but 7zip recently had an update-albeit a beta, and pretty much everything can be done from the context menu.

 

Just tested this on a semi-random folder with small, medium, and large files inside (with a lot of uncompressable/already compressed data inside, like .7z archives):

 

 

LZMA and PPMd yield the smallest zip'd file sizes--but LZMA is definitely the fastest, which is good. I'll be running some more benchmarks to test it out.

And v2 of it is used in .7zip files. So it should be better.

Yup!

Though to be honest all I do is

tar -czvf somefile.tgz somefolder

On a daily basis...

I'll be surprised if anyone still remember winzip

unless you are using computer in 90's and internet since early 2000, they've been considered unnecessary since WindowsXP natively support ZIP format, and no, they didn't support RAR either at that time.

 

While winrar and winzip are not free, but WinRAR still functional even without paying it, WinZip will be useless after 30days trial.

these compressing software were essential to our digital live because storage and distribution limitation, with floppy and barely 33.6kbps connection.

you will have a hard time without these software back in that day.

 

but eventually it will phase out, because faster internet, bigger storage, and better compressed method, these software no longer necessary.

You do it manually? I just use a .bat file with a vbs script to do the archiving in the background.

used winrar for years... I never open the files themselves.. always use right click menu... so i never get the "buy winrar" crap...

 

oh and i used winzip in the win95/98/2000 years. i'll admit i had a pirated version. Installed it so often i memorized the key for it :wacko:

7zip or PeaZip, because they are both FOSS.

Counting on the amount of data, my most frequently used data compression algorithm

is probably lz4, since that's integrated and enabled in ZFS. Most of my data isn't

very compressible, but it saves me about 90 GiB of space, which is nice (on a dataset

of ~3.3 TiB of uncompressed size).

Aside from that, when I do it manually, I usually use tar + <appropriate compression program depending on circumstances>

These days mostly it's the parallel version of bzip2, since it's reasonably fast and

achieves decent compression on the data I use it for. If I need really great

compression on large files and tons of time available, I use lrzip, which is specialised

for that task. It's extremely good at it, but it takes a very long time to get the job

done.

Agreed. Most of my data that is being compressed is full granular backups of my workstations and servers. So it's also stored encrypted... And has to be compressed twice: before and after encryption.
