^Organizing files on the computer is tricky business.

  There are as many systems as there are people - or if you're
  like me, you have multiple systems.

  My advice: Utilize the built-in features of the operating system
  as much as possible. They're there for a reason.

  Example: Sort by date descending. Your memory works by
  association - and you are likely to remember what you worked on
  before or after the project.

  What they call "Versioning": I DON'T save copies with the same
  name. Rather, each one gets the addition of the date or
  date/time at the end of the file name. It allows you to recover
  from catastrophic mistakes - and they WILL HAPPEN.

  As far as folder organization - I've worked in Excel forever
  among other software and what works for me, honestly, is simple:

  Dump it in one place but let the FILENAMES tell the story. (use
  the operating system sorting to its best advantage).

  When the folder gets slow or clogged up, move stuff untouched
  for a while into a subfolder to speed up directory access.

  That's it.

  Do your backups on multiple drives. The folder name should have
  the date of the backup on it.

  all in all - dates are #1 because they give you something to
  pinpoint. Vague filenames, folder names - you can easily spend
  more time maintaining your system than getting work done.

  Simplest is best.

  Fewest rules.

  I'm a messy organizer but I can always find my files. I don't
  keep them in places for other people to find. I keep them in
  places where I can find them.

  Too many categories can be detrimental unless they are set up
  how you think.

  PART 2:

  An even more sophisticated method that I've used is like this:

  NameOfPersonWhoNeedsMeToDoThisFoThem_WhatThatPersonCallsTheProject_DateOfThisVersion

  In the end, there's PROBABLY a person who wants this project the
  most: Having a person's name in the file for your own use
  internally speeds up the search process.

  It also helps in those vague times, where you get a call and
  someone says, "Hey! Do you remember that thing you worked on for
  me last year about that thing we were having trouble with?"

  and you're all like "huh?"

  But you can go into a directory, sort by name - and it REALLY is
  sorting by name: name of person and then by project, then by
  date alphabetically - all within the filename itself.

  Then you can see their name and go, "Oh do you mean the
  "WhatThatPersonCallsTheProject"? and then you can go down a fast
  "no no no YES" chain.

  And worse if they ask, "Yeah, I liked how you had it when we had
  that big office party, remember?, when you were testing out that
  idea you had, but the board didn't like it and you took it out?
  Well, I really want to see that again. I could use it again for
  a new thing I'm working on that I think you're perfect for".

  All the answers are in the filename. You'd go to your old
  calendar, find the date of the office party, match them up and
  boom, found.

  Even if you don't get that fancy with your system, changing the
  filenames as you save (and purging when necessary - but disk
  space is CHEAP now - might as well use it all!) - and including
  the dates just streamlines things tremendously. Operating
  systems hold on to SOME of that information in their
  "Properties" (like date created vs date edited) but for me, that
  was never enough information.

  Anyway, I'm glad to have had a chance to share this with someone
  who can use it! Best of luck to you in your organization skills;
  its a lifelong challenge. -simplify3 (Kenneth Udut 7/28/2014)^
