Byte Cipher File Size?

when I input the file size in byte cypher do I put the actual file size or the size on the disk?

also if there is a decimal do I round up or down?

I keep byte cyphering a file and it keeps telling me it is not a valid windows file when i attempt to inject it

wow I messed up

I meant elite encrypt, hopefully I still get help though with my error

Well whenever I use it it tells me that it is not a valid windows file
