Quick and clear as usual. Thanks, Acorn.

I placed an empty file, A4 Portrait.xar, in said folder but the app still tells me it cannot find it. So, I opened the file by double-clicking it and saved it as a template. The app suggested saving it here: C:\Program Files\Xara\Xara Designer Pro X\19\Templates\ENG. Now when I click File/New, it lists and opens the file. I also placed other template files and they now show. I guess the cache folder is only for the Local Designs Gallery.
