If you do the obj or fibermesh export, then you can no longer move the figure and have the hair follow. By default, if you save the scene with the generated fibermesh/obj hair, it will not reload. I have discovered that if you unparent the generated geometry and then save the file, the geometry will re-load when you re-open the file. I usually change the name of the new geometry though, too.
In the folder one higher up than what RAMWolff posted, there is a folder called "geometry." This is the location where the exported hair is stored. Since it does not reload when you re-open the scene, I systematically delete all the files in this folder after closing Studio, as they are unusable in future and just take up (lots of) space. The image files in this folder can also be deleted, as they are re-generated with each hair export. You can save them, though, if you want, and re-apply them to other generated hair presets for an unusual look. I just had a brainstorm, and am now off to check if the texture generated from the HiveWire Big Cat fur export will render as a leopard on other fur presets...
