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
