My StartUp Disk is almost Full, How do I delete files?

Recently I keep having this pop up on my computer that says:
Warning: Your StartUp Disk is almost full
Create more space by deleting files in your start up disk.

I must be confused about what the start up disk is.
When I go to System Preferences I go to startup disk there,
when I click on that it gives me normally two folders,
one is Mac OS 10.3.9 and the other is Classic 9.2.1
Now I got this other folder that says Network Startup
and it is dark and has a big ol question mark on it.
(which is appropriate as I have no idea what it is)

I assume that its telling me delete files I've accumalated
over the years from Mac OS 10.3.9 (I don't use classic)
which I presume includes everything on my desktop and its
folders. So I deleted a whole bunch of stuff. Huge files
and little files and lots of unimportant stuff. But still it
pops up and says "My start up disk is almost full and
I must Delete files from the start up disk."

How do I delete files from the startup disk if it is not
referring in general to all that is on my OS 10.3.9?

    Welcome To  Discussions McGoose!

    "When I go to System Preferences I go to startup disk there,..."
    That preference panel is only used to choose which system you wish to boot from.

    What size is the Hard Drive, and how much space is available?
    Do a Get Info on the Hard Drive icon, on the Desktop.

    Capacity: ?
    Available: ?
    Used: ?

    Insufficient available space, can cause performance issues, system corruption, and possible loss of data.

    Depending on Mac system usage habits, it is a general recommendation, to keep 10% to as much as 20%, of the Total capacity, available at all times.

    Review the suggestions, in the documents that I have linked to below.

    Maintaining Mac OS X, authored by Dr Smoke

    Is the Mac shutdown overnight, or does it run 24/7?
    Have you ever run any routine Maintenance procedures?
    If you turn the Mac off nightly, the Background Maintenance Tasks, are never run.

    These can also be run, using a Third-Party utility, or manually using Terminal, to run the CRON Commands.
    I use MacJanitor, when necessary.

    Quit all applications/programs.
    Navigate to HD > Applications > Utilities.
    Double click on Terminal, to open.
    At the prompt, type:

    sudo periodic daily

    Press Return.
    Enter your Admin password when prompted, then press Return.
    This will execute the daily script that is sheduled to run every night.
    When completed, repeat this procedure, but change the command to:

    sudo periodic weekly

    This one rebuilds a database or two, and usually takes somewhat longer to complete. It is scheduled to run once a week.
    Repeat again, with command:

    sudo periodic monthly

    Or they can all be run in one pass, which is preferable, with this command:

    sudo periodic daily weekly monthly

    When the tasks complete, and return to the prompt, you may quit Terminal.

    Restart the Mac, and run Repair Permissions.

    1.Open Disk Utility, located in Applications/Utilities, and select the startup disk in the left column.
    2.Click First Aid.
    3.Click Verify Disk Permissions to test permissions or Repair Disk Permissions to test and repair permissions. (I never "Verify". Just run "Repair".)

    Rerun RP, until the only messages reported, are listed here Spurious Permissions Errors Using: 10.3.x, authored by Michael Conniff.

    When "Repair Permissions" is complete. Quit "Disk Utility".

    Just out of curiosity, have you emptied the trash on your dock? If not, context click (right click, or hold ctrl and click) on your trash can and select "Empty Trash".

    If you already knew that, I don't mean to insult you. I've run into a lot of new users in my day that weren't aware that you have to empty the trash.

    Good Luck.

    You're Welcome McGoose,

    "Is there somewhere I go to empty start up disk cache or something
    like that?"
