Convert file to ASCII. Some transfer protocol only support ASCII. We can still use it by converting our file into ASCII.
Tools


uuencode
uudecode
tar
gzip
gunzip

Step


Let's say that we have movie.mp4 file.
Create arcive using tar and gzip

tar cfv mymovie.tar movie.mp4
gzip mymovie.tar

Convert mymovie.tar.gz into ASCII

uuencode  mymovie.tar.gz mymovie.tar.gz > mymovie.tar.uu
# You need to repeat file name twice!

You will find mymovie.tar.gz.uu content to be like this

begin 664 mymovie.tar.gz
M4$L#!!0`"``(`(!F(54````````````````<`!``26YF;W1A:6YM96YT7U-L

Now you can send it via email or MQTT or others protocol that support text(ASCII).


So you save the message in a file, complete with headers. Let's say you call this message-file.


uudecode message-file
gunzip mymovie.tar.gz
tar xfv mymovie.tar
