In my Terraria save files the world and player files are empty - where would my PLR file be?
Solution 1:
These files should be stored in %userprofile%\My Documents\My Games\Terraria\Players
(%userprofile%\Documents\My Games\Terraria\Players
on Windows 8/8.1/10).
Solution 2:
If you have saved your players and worlds the the cloud they are moved from you "my games" folder. Steam moves them to the "userdata" folder inside the steam directory. Inside the "userdata" folder there will be numbered folders for each person who uses your computer if its only you there will only be one folder. Inside your folder there will be numbered game folders, Terraria is number 105600. Inside you will find the "remote" folder that holds all your saves.
