Total size of two folders...

Hi!

I am trying to set the EstimatedSize for "Add/remove programs" and I can't seem to find what I am looking for.

My installation programs install itself in both $INSTDIR and $APPDATA and I can't seem to find what I should use to add up the size of what I installed in both directories...

I read about ${GetSize} and the Locate plugin but none of them seem to be able to do what I want...

The "weird" thing is that what I want appears to be what the "Modern User Interface 2" displays as space required... How can I access this?

Thank you and have a nice day!

Nick

And if you google "SectionGetSize" you will find more related information...

Thank you very much, it worked very well!

The installer I am writing is replacing an installer that used to be done with InstallShield and we never had such a good support (and that thing cost an arm and a leg...).

Once again thank you very much and have a nice day!
