When you export your map(s) it should list all the .fh files you need such as .fhm, .fho, .fhs, .fhw, .fhs etc.. Write down what the map has exported then go into your Exports folder.
Find all of those files then Copy & Paste them into a new folder (preferably on your desktop) so they are easy to find. Once you've done that, open up Notepad or any word document and label it as 'README' or 'INSTRUCTIONS'. Inside the document should be instructions on where to place the files, everything must go into FeralHeart\\Exports. Place the document into the new folder along with the other files.
Once you've completed that task, right click the folder and select 'Send to' then 'Compressed .Zip Folder'. Upload that folder to either Mediafire (http://www.mediafire.com) or SendSpace (http://www.sendspace.com/) (Both recommended). These are two easy file sharing sites. Be sure to upload the Zipped folder only.
Yep! The .fho files are the most important for meshes and stuffs~
