but you need to make it executable zip first then do upx

 

Compress files??

It all depends on the contents. Back in the early days of DVD games, they had plenty of space compared to CD's. So they left stuff uncompressed on the DVD itself. Compressing such ISO image would result in very high compression ratio. But these days, even DVD discs are becoming small and game companies are already using data compression to fit more data on the same DVD. And since you cannot compress already compressed data, you're seeing more and more of the 99% compresion ratio moments.

Good examples of such scenarios is when you want to compres uncompressed WAV file and a MP3 file. WAV is not compressed and you can decrease its size significantly. You might gain few kilobytes when trying to compress already compressed MP3. The same is with images. You can compress BMP images rather well but when compressing JPG images, you won't really gain anything as its already compressed.

There are few very specialized algorithms that may gain some more compression out of already compressed data, but the gains are usually very small and usually not worth the extra compression time needed to perform the compression itself. Plus you can only use them to compress very specific data files.

 

How to open a .exe file

Hi,

An EXE file (also known as executable file) contains an executable program for Windows. EXE is short for "executable," and it is the standard file extension used by Windows programs.

For us to better assist you with this, we'd like to know the following:

• Were you getting an error when opening a .exe file?
  
• Was it compressed (zipped)?
  

Usually, you can just double left-click the .exe file (if not compressed) to open it. However, if it's compressed, you need to install a 3rd party software to extract it.

We're looking looking forward to your reply.
