Disk space check
 

Hello,
I was wondering if there's a way to check if there's enough diskspace in the $INSTDIR directory for program installation.
If there isn't enough space the user would be prompted. I can use an IF comparison, however I don't know now to get the numbers for current space available and the space required by the installer. Are there special variables that store these values?

thanks.

The directory page already does that. You can add required size using AddSize or dynmically using SectionSetSize. For a manual check, you can use the following:
