how its possible..such high compression with winrar

[ashishstillthere]

Its simply this: compress sound files to .ogg format and compress game video files( .bik) into just half of them. Now compress all data with 7zip and rename it with .x extension......

(this is NOT my explaination).. but this is wat they (ppl like skullptura on torrents) do) maybe its not jus ONLY winrar...

hey beta testing plz tell me step wise how you did that i too have many iso's n nrg file

Your ISOs are useless to compress. Why? because the unpacking time be quite long. And after that you'll have to mount it or write it to a disk. Thats useless. So my suggestion is, just copy the ISOs to a DVD and be done with it. For your purposes, compression is useless.

thanks for your reply dheeraj.....actually i am making copy of my cd/dvd on my hdd because lots of people keep on taking my cd/dvd for their use as we live in hostel so i cant deny them and many times they get broken or get scratched then i have to go n arrange a new one for me so i wana back up them on my hdd so i dont have to get a new one in case of older one get some problem....thats why i need to compress them also so i dont have to loose more space...i dont have any problem regarding time taken to uncompress n burning coz it still very benificial for me then going to download or searching local vendor


but i dont want it to be done with kgb coz it takes lot of time but 1 hr or 2 hr is ok for me to let them uncompress but i didnt have to do that a lot coz only file compressed by me takes that time but the file downloaded by net is far good then mine as they have better compression ratio then mine and takes less time than mine file....this is the reason i wana know how to compress them effectively

well, i saw this reply by a user on torrents site..he didnt disclose the methods used, so i was also left wondering..but as he said, he has been studying this pattern of conmpression done by skullptura (this guys is the master of compression for games on torrents and helping low bandwidth ppl like us to d/load games) since the past 1-2 years..and guess wat, the "he" im referring so much in this post was actually an Indian boy and a B.Tech Computer Science student...similar to me (well im a B.E I.T)..

so this made reading his reply all the more fascinating will post anything tat i'll come across wen the "he" guy posts anything in future..

@ashishstillthere
No idea, I dont know about the compression methods professional releasers use. I'll tell you what I do, I have lots of software, games and movies, I write them into DVDs as my own copy, and when friends need them, I just copy them back to the hard disk, and write them into other discs for friends. I've been doing that for a long time, and all my master copies are safe for me. Of course, If I had another DVD drive it would be much easier, direct DVD-DVD copying, but I dont

I have analyzed some rips by Skullptura, and the most of the compression takes place using 7zip, which drastically reduces the file size.

It can't possible iff WinRAR is set to compress at its max. for it has the ability to compress particular files a lot and other very less.

And you can get better compression with documents.

Only with older Office 2003 format. Compression is almost minimal with ODF & OOXML as they are already compressed using ZIP.

Technically speaking, ODF & OOXML files are a group of XML files compressed with ZIP.

 

[ashishstillthere]

any one know other way to get max compression????

 

[cluby]

Even Windows ntfs Compression Can Achieve Very High Compression But Compression Depends Upon The Structure Of The Data Written In The File.

If U Have pop Ww Original Dvd Then There U Will Find An Single File Of Over 2.xx Gb Size.now Copy That File To Any Drive Which Is Formatted As Ntfs & Drive Compression Is Enabled On That Drive.

Now Right Click The File & Go To Properties. U Will B Amazed To See The Compressed Size.it's just Some Kb I Don't Remember It Now.

The Max Compression Over That File Is Achieved By 7z Format In 7zip, The Best Software For What It Is Meant To Do.

7zip is better

 

[ashishstillthere]

can you plz tell me the setting to get that compression in 7 zip.......

 

[dheeraj_kumar]

Read the command line arguments. I remember seeing a certain chain of arguments that give the max compression some time back.

*www.google.com/search?num=100&hl=en&client=opera&rls=en&hs=V83&q=7zip+command+line+bcj2&btnG=Search

has many argument chains.
