Interacting Gnucash with Windows

[Dr. Aldo Medina]

Hello. I'm using Gnucash 1.8.10 in Debian without
major problems (except a bug when deleting programmed
trasactions already reported to bugzilla) to keep my
personal books. However, since they are very useful to
me, I was wondering of sharing them with my
accountant, but he can only use Windows applications.

Which method would you recommend to share my
information with my accountant? Thanks in advance.
