copy - powershell iterate through multiple subfolders for differences and move to multiple targets -

relatively new ps. trying write ps iterate through multiple source , target subfolders same folder names. gci against each folder in both source , target, perform diff , copy differences sources target. have script working single sub-folder.

#############  source  ############# $s = "c:\logbackup\conversionexpress\" $src_conexp = [string[]](gci $s -recurse -include *.safe, *.done) #test location   ############  target  ############# $t = "c:\logbackup\conversionexpress2\"   #tst $trg_conexp = [string[]](gci $t -recurse -include *.safe, *.done)  #tst   diff -referenceobject ($src_conexp) -differenceobject ($trg_conexp) -passthru |    %  {        cpi -path $_ -destination $t -force      } 

my issue is, have 6 sub-folders in source , target need diff against , copy resulting diff's corresponding target file location.

here ugly r&d has got me:

#$pfolder = "c:\logbackup\"  $sfolders = $(gci "c:\logbackup\"); $tfolders = $(gci "c:\logbackup2\");   foreach ($s in $sfolders)  {     $sfile = (gci "c:\logbackup\$_" -r -include *.safe, *.done);    } foreach ($t in $tfolders) {    $tfile = (gci "c:\logbackup2\$_" -r -include *.safe, *.done);         diff -referenceobject ($sfile) -differenceobject ($tfile) -passthru |                              %  {                                     cpi -path $_ -destination $t -force                                 }   }            

i wanted maybe see if function found work well.

function getfiles($folder) {     write-host "+"$folder.name    foreach($file in $folder.files)    {        write-host "`t" $file.name    }     # use recursion loop through subfolders.    foreach ($subfolder in $folder.subfolders)    {        write-host "`t" -nonewline        getfiles($subfolder)    }  } 

any direction or me past appreciated. thanks.
