There's a new file in my emclient folder "mail_fti.dat-fix" it's more than 4 GB in size. It wasn't there originally. Can it be deleted?

There’s now a new file in my emclient hard drive folder: “mail_fti.dat-fix” and it’s more than 4 GB in size.  This makes it much more difficult for me to back up that folder to a jump drive as it substantially increases the size of the emclient folder. Can I delete that file, is it important?

Hi Steven,
this file can be created when the database repair tool is killed unexpectedly.
However, if your database seems to work and there are no error messages indicating any issues, it should be safe to delete.

Regards,
Olivia
