Function fs.getSize
Gets the size of a file in bytes. Returns based on the contents of the file - if "file.txt" contains 29 bytes of data, then fs.getSize("file.txt") simply returns the number 29. Earlier versions of ComputerCraft returned the filesize plus the string length of the filename - for example, if "file.txt" contains 1000 bytes of data, then fs.getSize("file.txt") returns 1000 + #"file.txt" = 1008. Furthermore, if the value would be lower than 512, then 512 was returned instead. These behaviours were discarded somewhere between CC 1.53 and CC 1.57.

-|desc=Gets the size of a file in bytes. This is not actually the exactly length of the file in bytes; rather, it is the amount that the file contributes towards the computer’s or disk’s storage quota. This is either 512 bytes or the actual length of the file plus the length of its name, whichever is larger.[http://www.computercraft.info/forums2/index.php?/topic/12243-152fsgetsize-returns-unexpected-values/]
