DevTool v6 - doesn't maintain links when renaming

[MorFologist]

Hi. I have received a set of v5 files from a new client with an extension of ".fm".

I have tried to use Dev Tool to rename the files properly, but however I set it up, renaming loses all the links (they show as File missing: Invoices.fm).

I tried replacing with .fp5, and just removing .fm.

Any ideas why Dev Tool is unable to re-link the files?

Make sure you rename all the files at once (ie, drag the whole solution into the rename panel). Do not rename them one at a time.
