Answer 1

Don't use the read() method since it reads the whole file into a string. You should use the os.stat() function to get the the file metadata, which returns a stat structure with the member st_size. That's the size in bytes of the file. You don't have to read it all in first.

For sending, also read in and write out in chunks (say 16kB), in a loop.

Answer 2

So, filein.read() actually reads (i.e. downloads) the file and is consuming your memory.
You can instead use

self.size = self.ftp.size(self.filename)
