Get total, occupied or free space of the drive.
Join two files in one (File1 + File2 = File3).




Syntax:
Syntax:
${GetSize} "[Drive]" "[Options]" $var
${FileJoin} "[File1]" "[File2]" "[File3]"
 
"[Drive]"     ; Disk to check
              ;   
"[Options]"  ; /D=[T|O|F]
              ;    /D=T  - Total space (default)
              ;    /D=O  - Occupied space
              ;    /D=F  - Free space
              ; /S=[B|K|M|G]
              ;    /S=B  - size in Bytes (default)
              ;    /S=K  - size in Kilobytes
              ;    /S=M  - size in Megabytes
              ;    /S=G  - size in Gigabytes
              ;
$var          ; Result: Size


"[File1]"    ; Input File1
"[File2]"    ; Input File2
"[File3]"    ; Output File3
              ;  If [File3]="" Then add [File2] to [File1]


Note:
Note:
