Re: sims 4 files

@astridou4  Yes, you can get rid of the 30 on the end, but you'll first need to renumber the save so it doesn't have exactly the same name as any other save.  For example, you could rename it Slot_0000000a.save or Slot_00000010.save, but you can't have two files named Slot_00000009.save in the same folder.  (That may be why the 30 is on the end, because duplicates with the same name were created.  But the game won't read a save file with an extra number on the end.)

The saves are numbered in hexadecimal, with eight total digits, including the initial zeroes.  The number in the save name starts at 2 (1 used to be the auto save, but it's not used anymore) and goes through 9, then a to f, and then back to 10, through 19, then 1a through 1f, and back to 20, etc.  But the saves don't have to be numbered in order, so you don't have to worry about getting all the numbers exactly right.  Just make sure there are no duplicates, and that every save ends in .save, and you should be fine.
