Easy steps.
Step 1: Make a .Zipped folder on your desktop. [Right click your desktop and select 'New >> Folder' then right clock the folder and select 'Compressed Zip Folder']
Step 2: Export your map & list everything that has been exported.
Step 3: Go to FeralHeart >> Exports & find all the files that were exported .fhm, .fho, .fhs, .fhw.
Step 4: Put them in the folder you made on your desktop [If it shows the folder as a WinRAR or 7Zip then open up the Zipped folder and drag the files from exports into there.]
Step 6: Make a document in word or notepad with instructions of what to do. [E.g. 'Place all files into Local Disk (C:)\FeralHeart\Exports.] and put it into the Zipped folder.
Step 7: Upload the folder to mediafire or to another file sharing website.
Step 8: Share the link to your friends
