Digital file manager, frenzied and fastidious, blowing top (10)
I believe the answer is:
manicurist
'digital file manager' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'frenzied and fastidious blowing top' is the wordplay.
'frenzied' becomes 'manic' (I've seen this in another clue).
'and' means one lot of letters go next to another.
'fastidious blowing' becomes 'ur' (I can't explain this - if you can you should give a lot more credence to this answer).
'top' becomes 'Ist' (resembles ust).
'manic'+'ur'+'ist'='MANICURIST'
Can you help me to learn more?
(Another definition for manicurist that I've seen is " pro with file?".)
