[h2 Using %sizedir.r

[p There are a few change that be made to this script.  You could
change the directory that is scanned, and the files that are included
in the total.

[h3 Running %sizedir.r
[p This utility is simple to use.
Just <strong>DO</strong> it.

[asis
>> do %sizedir.r
asis]

[p This can be executed directly from the library
[asis/style/font-size:75%

asis]
and will give you information on the %.r files in the 
current default directory.

[h2 What you can learn

[p How REBOL can return a block of filenames by using **load** on a
directory specification. In this example, **load %./**.

[p The REBOL size? function returns the length of a file.  Note
there are complexities to this in real life, as operating
system filesystems usually have **allocations** that don't match
actual file sizes.  But that is a more advanced topic.

[h2 What can break

[p By default, REBOL security settings do not allow directory
reads for most directories.  Modified versions of %sizedir.r may
cause a security question, unless you start up REBOL with the **-s** option.
