I can't believe that I am posting this, but I am desperate.
This SHOULD work, but craps out part way through...

 Code:
$DAYNUMB=@YDAYNO MOD 10
$APPDATA    = "C:\Users\mylogon\AppData\"
$TARGETapp  = "H:\Backup\Users\mylogon\" + $DAYNUMB + "\AppData\"

MD $TARGETapp
? "Copying " + $APPDATA
? "     to " + $TARGETapp
Copy          "$APPDATA" "$TARGETapp" /h /s /r /c
? "Error? " + @ERROR


The console result is
Copying C:\Users\mylogon\AppData\
to H:\Backup\Users\mylopgon\9\AppData\
Error? 0

Yet the target gets as far as creating:
H:\Backup\Users\mylogon\9\AppData
Then it ends. All folders are empty.
There should be about 900 files (!); that how many are on the source.

It seems like some kind of incompatibility with Windows 7 WTF ???
I am using latest version of KiXtart.

Thanks in advance...
