Anyone know how to make a master file outside of the Fallout Mod Manager?

[sovngarde195]

I'm trying to make a mod that adds changes to someone else's mod (which is a .esp file) and the GECK won't regard it as a master on startup and the only way to keep its files is by adding it as a plugin, which resets my progress on the stuff I've changed. Does anyone know how I could change that file into a .esm without the use of FMM (the only way I've previously heard of getting it to work)? Thank you in advance.

It can be done using FO3Edit and following the steps as described in the FO3Edit Training Manual. Both of which are available here on the Nexus.

That was quick- but seriously, thanks.
