Thanks sunjammer (Function "CheckSpaceFree")
Thanks Afrow UK (Based on his idea of Function "JoinFiles")




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
"[File1]"    ; Input File1
              ;   
"[File2]"     ; Input File2
"[Options]"   ; /D=[T|O|F]
"[File3]"     ; Output File3
              ;     /D=T  - Total space (default)
               ;  If [File3]="" Then add [File2] to [File1]
              ;     /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
              ;

You can use the latest version of headers (recommended) or the following function code (put the function code in your script before calling it)

Function Description

____________________________________________________________________________
 
                            FileJoin v1.4
____________________________________________________________________________
 
Thanks Afrow UK (Based on his idea of Function "JoinFiles")
 
 
Join two files in one (File1 + File2 = File3).
 
 
Syntax:
${FileJoin} "[File1]" "[File2]" "[File3]"
 
"[File1]"     ; Input File1
"[File2]"     ; Input File2
"[File3]"     ; Output File3
              ;  If [File3]="" Then add [File2] to [File1]
 
Note:
-Error flag if input files aren't exists
-Error flag if output file path isn't exists


Example1 (Join: a.log + b.log = Z.log): 

Section
	${FileJoin} "C:\a.log" "C:\logs\b.log" "C:\Z.log"
SectionEnd


Example2 (Add: a.log + b.log = a.log): 

Section
	${FileJoin} "C:\a.log" "C:\logs\b.log" "C:\a.log"
SectionEnd
