View source for AutoHotkey: Create .bat file to combine file parts

This script creates a batch file that can be used to combine file parts created using File - Split File.

Usage:
* create a button in the Button Bar or a Start menu entry pointing to this script
* enter "%L" in the Parameters field
* use by selecting file parts file.001 - file.nnn (do not forget to sort in ascending order) and clicking on the script button (menu entry)

 ; Check number of parameters
 ; %0% is the number of parameters
 ; In "If" it must be referenced as 0, not %0%
 IfNotEqual, 0, 1
 {
 	MsgBox, Error: Exactly one parameter "`%L" required.`n`nNumber of parameters passed: %0%`n`nExiting.
 	Exit
 }
 
 ; Check if listfile exists
 IfNotExist, %1%
 {
 	MsgBox, Error: List file "%1%" not found.`n`nExiting.
 	Exit
 }
 
 ; Check if default output file does not already exist
 FileReadLine, FirstFilePart, %1%, 1
 StringGetPos, DotPos, FirstFilePart, ., R
 StringLeft, OutputFile, FirstFilePart, DotPos
 CrcFile = %OutputFile%.crc
 OutputFile = %OutputFile%.bat
 IfExist, %OutputFile%
 {
 	MsgBox, Error: Output file "%OutputFile%" already exists.`n`nExiting.
 	Exit
 }
 
 ; Check if .crc file exists (to retrieve original filename)
 IfNotExist, %CrcFile%
 {
 	MsgBox, Error: CRC file "%CrcFile%" not found (needed to know original filename).`n`nExiting.
 	Exit
 }
 
 ; Create combine command string
 CombineString = @copy /b%A_Space%
 Loop, Read, %1%
 {
 	StringGetPos, BackslashPos, A_LoopReadLine, \, R
 	StringTrimLeft, CurrFileName, A_LoopReadLine, BackSlashPos + 1
 	CombineString = %CombineString% "%CurrFileName%" +
 }
 StringTrimRight, CombineString, CombineString, 1
 
 ; Get original filename
 FileReadLine, OrigName, %CrcFile%, 1
 StringTrimLeft, OrigName, OrigName, 9
 
 CombineString = %CombineString%"%OrigName%"
 
 ; Write .bat file
 FileAppend, %CombineString%, %OutputFile%
