Best Compressor..?

I always use zip or rar files to compress, but it depends on the kind of file you want to compress some type of files can compress a lot, but others not, in some there are no compression or very low. Another option is to split the file in several parts and send it in several messages or mails. i use winzip to do this. If not another option is the use of a file host like rapidshare, allows you to upload files up to 100MB (if I'm not wrong) and only you give the link to anybody you want for download the file. Hope it helps.

for you are confused because the file is full d computer or flash, I had a decent application that helps, that KGB Archiver .. function to compress files, so the results are compared with the initial 100.
