I was helping a normally not too PC savvy friend move some files around recently, and she told me she was going to rename all the photo jpgs in her family photo collection to coordinate with the events. As there were several hundred pics I asked her if she thought this was a good idea. She then proceeded to show me a trick she had discovered a few weeks ago that I had never heard of.
In windows explorer (C:\Windows\Explorer.exe) pane where it shows the listed files she tagged the files she wanted to change, then selected “rename” and named the first file in the selected list “Birthday Party”, then hit enter, after a second or two ALL the selected pics were named “Birthday Party” and were sequenced "Birthday Party (1).jpg, “Birthday Party (2).jpg”, “Birthday Party (3).jpg”, as they occurred in sequence.
I was surprised as I never knew this feature existed. It’s quite a time saver if you’re trying to categorize photos.
