what is the best way to compare files

[coles]

What i am trying to do is compare date of destination and source, and if source file is newer than destination it copies the file to source.

Just posting a sample code of what i am trying to achieve

 

#include <Date.au3> ; Include Date constants
#include <File.au3>
#include <iNet.au3>
#include <_XMLDomWrapper.au3>


Global $xml1, $xml1monthday, $xml1year, $xml1format, $xml2, $xml2monthday, $xml2year, $xml2format, $xmldate

; Runs the XmlDate() function to determine the age of the Xml file
;=====================================================================
XmlDate()

Func XmlDate()
$Xml1 = RegRead("C:\Temp\m1.xml","XmlDate") ; pulls registry

$xml1monthday = StringTrimRight($xml1, 5) ; takes the month

$xml1year = StringTrimLeft($xml1, 6) ; takes the year out

$xml1format = ($xml1monthday & "/" & $xml1year) ; reorders the date

$Xml2 = RegRead("C:\Temp\m2.xml","XmlDate") ; pulls registry

$xml2monthday = StringTrimRight($xml2, 5) ; takes the month and

$xml2year = StringTrimLeft($xml2, 6) ; takes the year out

$xml2format = ($xml2monthday & "/" & $xml2year) ; reorders

if $Xml1 = "" And $Xml2 = "" Then
   FileCopy( "C:\temp\a1.txt", "C:\temp\anokh", 1);
Else
   FileDelete("c:\temp\a1/txt")
   EndIf
EndFunc

 

 

Any comments will be appreciated 

Thank you

Have you looked at these functions? They are in the help file.

FileGetTime ( "filename" [, option = 0 [, format = 0]] )

FileGetVersion ( "filename" [, "stringname"] )

Or... I just found this one that I've used before.

#include <Misc.au3>
_VersionCompare ( $sVersion1, $sVersion2 )

@RickB75 Thank you

I think i will use Filegettime

if versioncompare has to be used,don't we have to add a version number in files?? i cannot edit existing files.

If you can use FileGetTime, you should be able to use 

StringCompare ( "string1", "string2" [, casesense = 0] )

to compare the two strings.

#include <FileConstants.au3>

If Number(FileGetTime("file1.txt", $FT_CREATED, 1)) > Number(FileGetTime("file2.txt", $FT_CREATED, 1)) Then _
    Msgbox(0, "", "file2 is older than file1")

Thanks @RickB75 @mikell for the replies.

@mikell with just 1 line of code you just showed how little i know about Autoit..

Many thanks as it works perfectly
