Need some help...
I have read through the messages on the boards and tried to re-use some of the posted code but to no avail...

Here is the nature of the problem:

I have created a simple installer that copy's 25 files in to the $INSTDIR. However this is an upgrade... I need a way to move files to $INSTDIR\backup directory *before* they get overwritten by the installer... Can anyone help? (BTW... I am Sooooo Not a programer...)

CreateDirectory $INSTDIR\backup
CopyFiles /SILENT $INSTDIR\*.* $INSTDIR\backup

That should do the trick.

Thanks...
I will try that. Is there any way to just backup the files that it is going to replace?

Well, you can if you want check for the existance of every every file and move it. You can make a simple macro out it:

!macro BackupAndExtract FILE ONAME

  IfFileExists"$INSTDIR\${ONAME}" 0 +2

    Rename "$INSTDIR\\${ONAME}" "$INSTDIR\\backup\\${ONAME}"

 File "/oname=${ONAME}" "${FILE}"

To use it:


CreateDirectory $INSTDIRbackup

>!insertmacro BackupAndExtract "C:\\dev\\whateverfile.something" "outputname.st"

># NSIS will only delete this dir if it's empty

>RMDir $INSTDIRbackup

Error in macro BackupAndExtract on macroline 3

Any thoughts? We are getting closer BTW... thanks!

You need to replcae outputname.st with the output name of your file. For example:

!insertmacro BackupAndExtract "C:\dev\Core.dll" "Core.dll"

OK this works:
!insertmacro BackupAndExtract "C:\dev\Core.dll" "Core.dll"

But if I have a file:
!insertmacro BackupAndExtract "C:\dev\XML\stuff.xsl" "stuff.xsl"

It does not get backed up...

Any thoughts?

Here is the new version that works with sub folders too:


macro BackupAndExtract DIR FILE

  SetOutPath "$INSTDIR\\${DIR}"

 IfFileExists "$OUTDIR\\${FILE}" 0 +3

    CreateDirectory "$INSTDIR\\backup\\${DIR}"

   Rename "$OUTDIR\\${FILE}" "$INSTDIR\\backup\\${DIR}\\${FILE}"

 File "<insert app dir here>\\${DIR}\\${FILE}"

>!macroend


>!insertmacro BackupAndExtract "" "Core.dll"

>!insertmacro BackupAndExtract "subfolder" "AnotherDLL.dll"
