How can I achieve a high compression file compression rate?

Muhammad Farhan May 13, 2012

Just now, I have copied GTA SA from my friend’s pendrive. The size is 670MB, but when I extracted it, it became 4GB. How to highly compress file like that?

    KGB archiver is the best solution, other options 7zip or peazip
    but you should remember different formats compress in different way thus it depends on the type of file you want to compress.

    please do reply n give us more detail. what u mean by extracted it? is that mean the original file is 670mb n after u extracted it it became 4gb? n if that the case, in what format that the original have, zip, rar, or what? or the original file is in self extractor format n u extracted it n it became the original size. or perhaps the file u have is it main installer n when u want to install it, it need 4gb to fully instal it? please do brief more on ur question. n if such case happen when the installer size is 670mb n when u want to install it it became 4gb, then it no problem at all, all file is compress to image in any installer, that why u will be suprise by it actual size needed to install it. n it u say my guest is correct n u just want to know what program that can compress the data while u still able to access it just like i ask in the past, then nothing to do to help u in such case, u just need additional hard disk drive or just let the game install in other drive by selecting the target drve to install it. but seriously we need more data to help u. this is such a major question n we dunno where to begin to help u

    Ha14's advice is sound as an all-in one solution, but there's actually no single answer to your question.
    Compression ratios depend a lot on what data you need to compress in the first place. JPEG and MPEG data, for example, is already compressed and will not compress much further regardless of the software you use. Text files, on the other hand, can be compressed to anything from shrunk by 50-90% using 7zip or RAR, Program files (e.g. EXE, DLL and COM files) can be compressed a fair amount (50%+) by being saved in .CAB format, and so on.
