compiling, but very broken code
refactored upload, completely untested

..not likely functional either
upload (seemingly) functional. only download left for the issue
date upload & recovery is functional, exception when writing to disk

almost there!
up and  download work unencrypted (w/date and filesize concat)

all thats left is to encrypt the file before concat, and decrypt after
group/date specific encryptiong works after some shallow testing

HOLY SHIT IT WORKED
merging file transfer
