Shoulder burden of file transfer? (6)
I believe the answer is:
upload
'file transfer?' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'shoulder burden' is the wordplay.
'shoulder' becomes 'up' (I am not sure about this - if you are sure you should believe this answer much more).
'burden' becomes 'load' (synonyms).
'up'+'load'='UPLOAD'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for upload that I've seen before include "Transfer from a remote computer to yours" , "Transfer data to a larger computer" , "post on YouTube?" , "Transfer (data) to a large computer" , "add data to system" .)
