Gil,
I got it. Just in case it referenced 3072 channels I expect that was from my original conversion from LSP to Xlights. I added the new D:\ drive location the file and deleted the old reference to C:\ drive. What is curious for me is that file really needed or do those channels exist in the new xlights file .xsq?
Since I can't see the original effects that were converted from LSP then I am not sure if I can get rid of the data layer file or not without extensive testing of old AC Channels and some RGB stuff.
Can you shed any light on my concern?
BTW Your suggestion on the data layer is exactly what I needed for now to get past the hurdle to relocate that file just in case.
Thank you,
Greg
