Somebody ask about that in the past. The name of the files after the exporting are: the name of the file and the time in linux format i believe, but is hard to understand and to organice.
Is not possible to change the name of the file to a more human readable time format?
from: Template-book-1514560008.odt
to: Template-book-20171229150648.odt
or something like that Year-Month-Day-Time
thanks
