Get size on disk: Difference between revisions

Revision as of 10:25, 12 February 2013

This example code shows you how to get the space used by directories and files.

; A utility for computing the NSIS (or NSIS Unicode) install folder size and the size of
; the uninstaller
; nsissize.nsi

GetFileAttributes is borrowed from filefunc.nsh. GetSizeOnDisk has been altered slightly and renamed. The original macro is called GetSize. You will find it in the Users Manual under E.1.3.
