Animation question

Hi, I have FBX animations in one file, I would like to separate them into individual FBX animations. I understand that I can use the file as is but doing so can be problematic, is there a simple program or solution to separate them. From everything I have read there is no easy way.

If not, is there a good tutorial an using them from a single file?

TY.

TY, trying Autodesk, never gives me the takes form the file when it put it in take manager, just keeps outputting single file, hmm, have to take a closer look. any goo d tutorials on using the animations in a single file?
TY.

TY. I put the original file in the converter and convert, then drag it to the FBX take manager, it never shows me the individual animations and when I try to save them as such, it only saves that same 1 file again. Followed the vid several. Any ideas.
