Well, I save all my files in the .docx or .xlsx format, which is the format for Office '07. If I'm going to try to copy LauraDO and give out my Histo (and beyond) notes, I want to know if I have to save my files in both 97-2003 format and 07 format. I know it'd be simpler to save in the older format, but it is just easier to have one copy of files on my PC than two. I type up all of my notes, so you can see how that would get a bit overwhelming.
On top of that, once or twice or thrice a month I like to go through my PC's files and compress space, deleting anything I do not need and organizing what I do have. If I were to make both save files, my folders would look like:
- My Documents
- College Documents
- Medical School Documents
- Histology
- Anatomy
- Embryology
.. and so on. I know that probably isn't necessary, but I hate my files being disorganized on my computer.
