Multi-turn user requests:
user: Hey there, I need to set up a directory in my current workspace. Once that's in place, could you help me locate a file in this vicinity and transfer it to the new folder? After that, I'd appreciate if you could find and open up a specific document, then scan through it to identify lines that mention a particular topic. Also, could you let me know the total number of lines in this document?
user: The directory should be titled 'Reports', the file to locate is 'summary.doc', the document to open is 'data.txt', and the topic to scan for is 'Q4 financials'.
user: On a different note,Could you get the mean of character number of all files in current directory?
