A question about load splayed table

Hello everyone, I have a question ask for your help.
I exercise the splayed tables, there is a question when I load splayed tables.

The detail of the question on the photo, the question is .DS_Store, it different from the case result.

So how can I deal with it, Thank you!

DS_Store needs to be removed in order to load via \l, unfortunately I think the file tends to regenerate. The following link discusses 2 possible methods for getting around the problem: https://groups.google.com/forum/m/#!searchin/personal-kdbplus/Ds\_store/personal-kdbplus/YmI8ENM3aRs
