#5 Add checksum

[Anonymous]

Could you add a checksum for the transfer?
Sometime, you could have some FTP connection
problem. The Handle is closed and the system
considered that the transfer is well done but it’s not the
case.
That’s why I think, it could be great if you add a check
sum. It will check the file size of the source and the file
size of the destination. If they are the same we can
consider that the transfer is good. If it’s not the case,
throw an error.
The size could be retrieve by the “dir” function.
