If you want to compress your data, which compression software that you prefer?

I was using two different compression software, the winrar and 7zip software. Why? They are free. The 7zip is much better because it compressed more as compared to winrar, however, if the user doesn't have 7zip installed, then they cannot open the file. Same thing with winrar, the user must have winrar software installed before they can open the file. But seems winrar are already popular. But the safest is winzip, almost all the PC have this software installed to uncompress files.

WinRar. I prefer it to many other compressors/decomperssors as you can try to decrompress any files you want, not only .zip or whatever

Winrar of course. If it is demand winzip file, I will use winzip. I choose winrar because most of the compressed files are rar type. I believe it will be convenient to every one who want have the compressed file.

winrar. probably one of the best trusted and reliable program

I haven't notice the compression ratio or speed of each program, but I'd prefer the compression ratio because compressed data are meant to for your archived files and you would expect to open it once in every 2 years. So the data should consume minimal space as possible. I use 7z because its free but it cannot decompress multiple-span zips. There was a free software with a very high compression ratio but i cannot remember the name and i found it to be unstable.

I use aes encryptor to compress my data and give them passwords.. it's very usefull and works great with my file manager..

Tryed a few... Zip is the most used because windows supports it, but rar files are around alot too because it is a decent software. Currently I use mostly winrar because it is used all around now-a-days and its an ok program with decent rates. Tryed many others like 7zip, uharc, kgb and more. Some offer really interesting compression ratios but most people don't know them or cant use them, so I ended up not using them too.
