Welcome to Apple Support Communities
Correct. Use the Finder to navigate through your user's folders and delete the files you do not need anymore.
If you need all the files you have, you can move them to an external drive, so you will keep them after moving them from your computer's drive.
You should never have your hard disk that full - your OS needs room to function properly, so keep - at a very minimum - about 10 - 15 GB empty at all times. More is better. If you are into video editing/rendering, you should have as much empty space as the temporary files in that project; as an example, my last one hour HD project had 150 GB of temporary files in it, so I keep a much larger portion empty at all times.
For information about the Other category in the Storage display, see this support article. If the display seems to be inaccurate, try rebuilding the Spotlight index.
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.
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—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the 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.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. 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. 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. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside a photo or iTunes library will corrupt the library. Changes to such a 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 or GP 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 the app 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.
For ODS:
security execute-with-privileges /A*/OmniDiskSweeper.app/*/M*/* 2>&-
For GP:
security execute-with-privileges /A*/GrandPerspective.app/*/M*/* 2>&-
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 and start typing the name.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password.
The application window will open behind other open windows. When you scan a volume, the window will eventually show 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.
When you're done with the app, quit it and also quit Terminal.
Empty the trash in the Dock as well as iPhoto’s trash!
Open up your application folder & go through all your apps. Trash all the apps you no longer want and/or use.
An easier way to do this is to open the Application folder in list view & press the Command+j keys.
In the the dialog that appears, click the "This Window Only" button & the "Calculate All Sizes" check box.
Wait a bit until your file & folder sizes have all been calculated, then click the "Size" column to sort your apps from the fattest to the most anorexic.
Get rid of all your photo files you don't want and/or need. Same goes for those pics off the websites you downloaded (gifs, jpegs, etc.). Or transfer/move them all to a photo/movie storage site like ImageShack and Photobucket, 2 of the most popular FREE storage sites.
Get rid of all your video & music files you no longer view and/or listen too. Especially, if you already have the actual CD/DVDs or you can later redownload from a website. Or transfer them all to a FREE video/movies and/or music storage site.
Use Spotlight to make sure you got rid of everything. You can even trash directly from Spotlight! Better yet, download this FREE software called Find File. This app puts Spotlight to shame (works w/Mountain Lion).
Drag what you don't want and/or need to the trash. Better yet, download this neat little shareware app *demo* called AppZapper. It basically does all the work for you by not only trashing the apps but the apps preference files, caches & all its associated files.
Another software that does the above is AppDelete. Best of all this software is free!
Burn what you want and/or need onto CDs or DVDs. Not everyone has the luxury of purchasing an external HD and/or the system requirements for iCloud to store their "stuff.”
Dropbox is a free storage utility to check out.
You can check with your ISP to see if they offer *free* storage space. Most if not all do now-a-days. There are thousands if not millions of *free* storage facilities on the web also. Use your favorite search engine to search them out as they come in different storage sizes to fit your needs & wants.
Check for duplicate fonts.
Applications>Font Book
Select “All Fonts”
If you see any “black dots” next to any fonts this mean you have duplicates and/or multiple versions of these fonts.
To clean this up, select a “black dotted” font or the Apple + *click* to select multiple dotted fonts;
Edit>Resolve>Duplicates.
What the above does is turns off the duplicates & multiple version fonts. Not delete them.
More than likely the “extras” were installed by other programs and/or other users.
Clear out font caches
Use FontNuke. It does all the work for you. And, best of all it’s *FREE*.
Printer Drivers
Get rid of all the printer drivers you don’t need & use except the ones for your *current* printer(s)/scanner(s).
HD>Library>Printers Folder
If you accidentally threw something out that you needed for your printer/scanner it can be easily obtained from the manufacturer’s website and/or from the CD that came w/the printer/scanner.
Garage Band
Has about 1GB of loops stored. Get rid of some some them. You surely don’t use, like and/or need them all.
HD>Library>Audio/Apple Loops>Apple>Apple Loops For GarageBand
Or just get rid of the Garage Band app altogether if you don’t use it.
Get rid of extra languages
Strip your computer down to your “native” tongue.
You can do this with a *FREE* utility called Monolingual. Another app that apparently does all the work for you. I’ve never used it. However, a lot of users here swear by & recommend it highly.
However, there is a warning for *native English speakers*. Make sure you keep BOTH English and English (United States).

==================
Rule of thumb: You should never let your hard drive get to where you have only 10-15% of space left.
