Encrypted EXE VS Compression Ratio

Many of us may concern about security of our application. We never hope our hard work (source code) being "stolen" (decompiled) by other developers. Because of that, some of us may choose to encrypt our EXE using VFP native encrytion, ReFox or other decompiler tools.

However, that is a downside. The compression ratio of encrypted EXE is usually less than 2% while "normal" EXE can achieve about 30% and above depend on your code. That means, it takes more disk spaces and longer time to update client application via WAN, Internet and diskette.

So, we better think about it, is security more important or ease of maintenance (speed of update application)? Alternately, exclude certain VCX, SCX, FXP files from project may solve the problem. What do you think?
