Sorry, I wasn't clear.
I have 2 partitions with the old install (Zenwalk). I installed VL light using these partitions. The /root partition I set to overwrite; it's what I intended. The system itself works fine.
The /home directory was mounted on the second partition with install set to mount /home with no formatting of the partitions. I intended to keep the files intact except for what I knew may be overwritten in the user root directory (e.g. program .config files etc. that were common between the 2 distros) Unfortunately, it didn't occur to me that the old directory Desktop, which had a fair number of files in it would be replaced by VL's version of desktop. So now, if I look in the desktop directory, I see the VL desktop icons and that's it (ie. welcome.desktop, etc.).
I'm hoping to recover these files.
