What is an FML file

FML files mostly belong to Forge by Forge. An FML file is a modification package for Mincraft video game. It contains data which Forge API applies to Minecraft in order to customize various aspects of the game. Another type of FML file is a file mirror list for downloads performed by GetRight download manager. FML is also the filename extension of a file mirror list used by Oracle Database. The Message Viewer developed by Advansys can open FML files containing GroupWise messages. Thunderbird email client uses a different FML file to save email summaries. FortiMail email security tool saves its blacklists and whitelists in FML files.

How can I open an FML file?

You need a suitable software like Forge to open an FML file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your FML file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FML file directly in the browser:. Just drag the file onto this browser window and drop it.
