Bruce,
I think no-one has answered this question. I rename the folder from within LR: right-click on the folder name and select "Rename" from the local pop-up menu. I don't do any manipulation of files and folders outside LR. You can also move a folder by clicking on it and dragging it. The designers of LR have really tried hard to build a complete self-contained workflow tool and I think they've done a great job.
(Changing the subject) When I import, I have LR automatically rename the files using the template TMYYYYMMDD_filenum. (TM are my initials). I don't use the camera's file name because it is not guaranteed to be unique (the counter can be reset, or it can wrap around). Keeping the original file number helps to locate the original if you also backup the photos from the camera or use LR's backup feature ("Make a second copy to..."). I also do the same as some others who have posted here, importing into a folder hierarchy of the type 2013/2013-01-04. I later rename the folder, adding a descriptive suffix, e.g. "2013-01-04 Four Towers". (There appears to be no way to set up LR to prompt for the suffix at the import stage.)
What book did you order? I'm interested in getting your feedback after reading it.
I started learning LR by watching Julieanne Kost's videos, which are excellent. Then after using LR for nearly a year, I bought the book "The Adobe Photoshop Lightroom 4 Book, The Complete Guide for Photographers" by Martin Evening. Even after using LR for so long, I learned a lot from the book. Its emphasis is on its functionality; it doesn't prescribe one way of working, but simply explains how the program works (although it does teach a little on the best approach to using the Develop module). I now use it more quickly, after learning many keyboard shortcuts from the book. LR is a very deep program and you really benefit from reading a book about it.
Evening's book is great for learning LR's functionality, and I'd like to complement it by buying another that teaches creative techniques using LR. Does anyone have any recommendations?
