Error box says startup disk is full?

Keep getting message that startup disk is full? What does that mean?

Hi Yvonne! Hi Tracy!
Which OS you are on? (Go on Apple-Menu top left and "about this mac"). There has been an issue with with 10.7.1
Please update to 10.7.2
To watch the space of your HD I recommend GrandPerspektive
http://grandperspectiv.sourceforge.net/
There is an other tool, which I don't know, but others recommend: "WhatSize"

its saying startup disk almost full. have no music or photos on computer. how do i clear it up and free up the HD

There are some items to the right of these reply boxes,
of them a few are likely to be of help to some extent...
Without knowing which OS X version, advice will be not specific
and to answer three different ways when one of them is correct
is a waste of time.
Is your OS X newer than Lion 10.7.5? IF so different rules apply
to finding out what is free space, where it is, & how to tell if it is.
For systems older than Lion (Snow Leopard, Leopard, Tiger, Panther)
the rules are a little different, since there would not be an Other item
on the hard disk drive which could contain items necessary to the OS
yet not detailed to the user.
And Lion 10.7 has a few hidden files that are hard to locate, and one
of them may have some bearing on the missing space of a HDD.
The items here, mostly for 10.7:

There are Support articles, you could use Help viewer in the
system, on your computer, to look for results; or use google.
However, avoid the temptation to use a badware such as cleanmymac,
mackeeper, and others that are sources of known trouble to the Mac.
Good luck & happy computing!

My mac air says " startup disk is full".How to solve ???

My Mac air has a message during starting the computer and says that startup disk if full. In the composition of my hard there are 120 GB used space on other parts, which I have not understand where is these files.

First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
If you're using Time Machine to back up a portable Mac, some of the available space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual. Quit it if it's running.
Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders. It may take some minutes for ODS to list all the files.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal.

My computer says startup disk is full but it isn't. Is there a fix?

I'm getting a message saying my startup disk is full, and I need to delete files. However, I'm only using about 15% of my hard drive (macbook is less than a year old). Any suggestions what might be going on?

How do you know you're only using 15% of the hard drive?
There could be a number of things going on. In the first instance, I'd run Applications/Utilities/Disk Utility and use it to run Verify Disk.

What can I do when my macbook air says startup disk is full

What can I do and where do I look to offload things when my macbook air says my startup disk is full?
Thanks

Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.

The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.

If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.

Imovie won't let me save my movie as a file, and it says ''startup disk'' is full!

I made a movie on Imovie and it won't let me download or convert, I don't know what else I can do, and also it says my disk is full, and my macbook is 64 and its impossible, i dont have that much. please help me. I want to save my movie and fix disk because is making my computer slower and doesn't let me save anything because is ''full''. I need to find a way to save the movie complete and as a file and make my computer faster and with it's original memory.
HELP!.

I have the same problem and then some. I movie won't share this particular project, but it also won't save any changes made to it or any other project. At least that's what it started doing, now when I go to even try to make any changes it wigs out and things get scrambled in the Project window and it plays video from another project.
When I create a new project, the Share menu is available, but it won't save changes to that project either. And by that I mean I can put stuff in the project and do whatever, but as soon as I quit and relaunch the application, the project is empty. I did figure out that if I make changes in a new project and immediately share it to the media browser that it will save the changes, but then it messes up my other project even more somehow!
Tried archive and install, deleting plists, reinstalling iMovie and iLife support stuff (twice), repairing permissions, and changing permissions in the project package. Any other ideas?

HT3680 My 3 year old iMac is freezing and I get a message "startup disk almost full for running applications. delete files..." Where do I find the startup disk and what should I delete?

My 3 year old Mac is having trouble and freezes up from time to time lately. I get a message saying "startup disk almost full, delete files ..." something about having enough room for applications to function. I know my startup disk is the Macintosh HD, but what kind of files do I need to delete and how much space do I need to free up? In my "about this mac" area, it says I have 4.89gb free out of 319.21 So I am confused why I need to do this.

You're less than 2% free and should always have at least 15% (my SWAG). Best is to get an ext FWHD and move stuff from the startup disk to it and delete it from that. Best things to move are movies, music, and photos, using the apps that manage those things.

I'm getting a message that says my startup disk is full

I'm getting a message that says my startup disk is full and I need to delete files. Which files and how do I delete them. My computer is becoming real slow and the color wheel comes on a lot of the time. HELP!!!

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

To see how much disk space is available ...

Hi,A message on my computer keeps coming saying my startup disk is full.what can I do to solve this problem??

You need a minimum of 5GB free space, and typically you need about 15% free space.
Your Mac needs adequate hard drive space to operate normally. A low amount of RAM requires more drive space for Virtual Memory’s swap files. Problems from insufficient RAM and free hard disk space are discussed in this link http://www.thexlab.com/faqs/lackofram.html
Look at these links.
