"Everybody compresses files, whether it be to send your documents over e-mail or you just have no space left on your hard disk drive. With all the types of file compression there are, how do you know which one is the best for the task you want to accomplish? Well, that is where this article comes in handy."

i compeltely agree, i don't use winrar, winzip anymore i jsut use 7zip. but my zipping needs i still love Total Commander

Only reason I ZIP files is to put a bunch of stuff together when I'm sending it. Like if its a bunch of pictures I'll zip it so I don't send them 1 by 1. With today's HDDs and DVDs there is no real need to zip your stuff. Everyone has enough space on their HDDs for zipping to be completly irrelevant to their space.

Thats my stance:


Zipping is only to archive things for sending so that it saves TIME not space.

Yeah, because high efficacy isn't important...

Besides that, what about when you're downloading seven gigabytes of .avi files? They'd compress better, so they'd download faster.

7-Zip is also a free compression, unlike RAR.

Yes but on a 7 GB file 100 MBs More or Less isn't REALLY going to make much of a difference. I mean your going to be downloading it for 20 hours, whats an extra hour?

You're on the way to Florida. It takes a good twenty-four hours to get there, but wait! You find a short-cut. You can skip some stupid interstate, and save one hour if you turn left right here.

Do you turn left? You're in the car for twenty-four hours. What's an extra hour?

QFE.

Lol, Shortcuts are good. But once again, I wouldn' go to great lengths to compress something so damned much, I remember when we used maximum compression on PS 7.0 which was a file of 100 Mbs it took off 10 mbs and it took a good 20 minutes to uncompress, which in the long run look longer than downloading the extra 10 Mbs.

[ubercanuck]

right but it depends on what your compressing. Take for example compressing a video file that is already encoded into divx or xvid, etc isn't goin to compress that much since it's already in a compressed format, but take say a text file that will compress incredibly well.

My Example.

350MB file compressed down to 345MB using 7zip (346MB in Rar) and it took 4 minutes to compress it. While a 17MB TXT file compressed down to around 3KB using 7zip.

Now for the compression speed. It takes be around 45-50 seconds to decompress the video file and 3-4 seconds for the text file.

IF you want i can try to take some screen shots to prove this but i think my sig speaks for it's self.

[SaSa]

Yeah, you have a pretty sweet rig. Now my question to you is where am I going to get my hands on a 17 MB Text File?! The Largest one I've had is my Functions.php file and its about 1 MB and its like 21093750923457 lines of code...

[Dalponis]

I had a text file that was a few gigs in size. Compressed? 17 Mb.

[SaSa]

Nice, thats Uber space save. You guys might have a Convertee here.

Download that. Watch the entire thing. That is the best file compression. Roughly 1.8 gigs into 64kb. For more example go to: http://www.theproduct.de/

Although you guys make great points,

Compressing is only used commonly for emailing attachments to bypass email security controls( .MDB and .EXE files will be blocked by most POP3 and webmail), and reduce size as some people still use DIAL-UP.

with .75 terabye HDD's common now, it is pointless to slow down data transfer on your system... ever.

not even for a few seconds... to save a few meg.

What a fucking idiotic comment...

With multiple core 3.65GHz processors common now, it is stupid to not compress things that should be compressed. You know, databases never need to be compressed. And hell, who cares about downloading smaller files.

'Tard.

Sorry for the necro-post. That was something I wanted to say for many years.

No need to apologise, was worthy saying a brought a wry chuckle to my face
