Component Size
Hi,

I want to check whether there is enough space to install the program. In this case I want to check the total memory size occupied by the hard disk memory. Is this requirement really necessary, If that so how can I get the size of selected components?

The command reference is your friend:

http://nsis.sourceforge.net/Docs/Chapter4.html#4.9.13.8
http://nsis.sourceforge.net/Docs/Chapter4.html#4.9.13.2

(You can also use SectionFlagIsSet from sections.nsh for more convenience.)
