Is it possible to convert a .mysql file to a .sql file? I am facing an issue with a MySql dump file (i.e mydump.mysql) generated by a Drupal export module. I am trying to import it on a local Drupal installation via Acquia Dev Desktop.

When browsing for my dump file, this application filters for .sql, .sql.gz and .mysql files. I thought it would load my .mysql easily, but I get an unsupported file type .mysql error. 

Is there a way to convert my .mysql file into a .sql file, knowing that I don't have access to the original database used to generate my mydump.mysql? I would like to try to feed a .sql file to Acquia Dev Desktop instead.

P.S.: I am on Windows 7 if this is relevant. Thanks.
For the records, I finally managed to load my dump into Acquia Dev Desktop after renaming the file to .sql and specifying/using exactly the same database name as the original database name.

I don't know what caused the original issue or what solved it, since I don't believe the database name should be an issue at all.
