create color theme under new folder, come back it is gone. how to save a palette

[mintintegral18]

there is an option [ view tab] to remove unused named colours automatically when closing file, this not active/ticked by default - so make sure this has not been ticked

thanks. The utilities, View Tab setting worked. They are now staying in Xara project. There is a free Cyotek palette editor, that exports to .pal files. copied it into, C:\Program Files\Xara\Xara Designer Pro X\15\Palettes, and then opening. Then Xara creates a folder for it in Color Gallery, but gives error, Can't open that file type. It is .pal like the other files in this folder. Any ideas? Thanks.
