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?

Beaver

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}"
!macroend 

To use it:

CreateDirectory $INSTDIR\\backup
!insertmacro BackupAndExtract "C:\\dev\\whateverfile.something" "outputname.st"
# NSIS will only delete this dir if it's empty
RMDir $INSTDIR\\backup 

Boy this humbling....

OK So I am obviously doing something very wrong....


Can you look at the attached and tell me where I am missing the point....

You have read the old post 🙁

I have edited it since you have read it... Please read it again.

Ok saw the new post. Made some changes. But getting a compilation error:

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

Beaver

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?

Beaver

Attach the script please.

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" 

That Worked! Thanks you VERY much for your help today. With out it I do not think we could have met our deadline...
