Once that's in place, could you help me locate a file called 'summary.doc' in this vicinity and transfer it to the new 'Reports' folder? After that, I'd appreciate if you could find and open up 'data.txt', then scan through it to identify lines that mention 'Q4 financials'. Also, could you let me know the total number of lines in 'data.txt'?
user: On a different note,Could you get the mean of character number of a set of files?
