Features:
1. Find the size of a file, files mask or directory.
2. Find the sum of the files, directories and subdirectories.
 
 
Syntax:
${GetSize} "[Path]" "[Options]" $var1 $var2 $var3
 
"[Path]"      ; Disk or Directory
              ;
"[Options]"   ; /M=[mask]
              ;     /M=*.*         - Find all (default)
              ;     /M=*.doc       - Find Work.doc, 1.doc ...
              ;     /M=Pho*        - Find PHOTOS, phone.txt ...
              ;     /M=win???.exe  - Find winamp.exe, winver.exe ...
              ;     /M=winamp.exe  - Find winamp.exe only
              ; /S=No:No[B|K|M|G]
              ;     /S=      - Don't find file size (faster) (default)
              ;     /S=0:0B  - Find only files of 0 Bytes exactly
              ;     /S=5:9K  - Find only files of 5 to 9 Kilobytes
              ;     /S=:10M  - Find only files of 10 Megabyte or less
              ;     /S=1G    - Find only files of 1 Gigabyte or more
              ; /G=[1|0]
              ;     /G=1     - Find with subdirectories (default)
              ;     /G=0     - Find without subdirectories
              ;
$var1         ; Result1: Size
$var2         ; Result2: Number of files
$var3         ; Result3: Number of directories
