Delete files to save space

How do I most effectively delete old files in order to maximize HD space?

Identify the biggest files on your hard drive -- often they are feature-length movies -- and decide which of them you can get along without.
Don't bother with little files. Finding and deleting thousands of them may not save you as much disk space as trashing one full-length movie.
This utility will help you find your big files:

Trimming the fat - moving and deleting files to save space.

I have a bit of a dilemma. I have a large number of applications that require to be installed on my startup disk. Thanks to large audio libraries and plugins, it just about fills it up.
I was fortunate enough to have put in a second internal HD (props to ME and their optibay) so I was able to move things like the audio content of my iTunes library over to that drive, my Aperture library, and a few game like WoW over there, savings tons of space. However, after a disaster corrupting my drive, I had to wipe and reinstall the OS and al of the software from scratch. I had about 2GB of space left. Here are some areas I think can be moved or "trimmed:"
• Printers. I've dumped all of the printer drivers I'll never use, freeing up 3.5GB worth of space. It's a good start.
• When reinstalling my audio apps, I started with Logic Pro 7, then all of the Jam Packs I had, and the Logic Pro 8. It looked like 8 came with all of the Jam Packs already had plus another one or two I didn't. Did it write over, or skips the already-installed instruments, or did it create multiples stored in slight different locations. This has the potential of shaking out a few more GBs.
• Loops. The Jam Packs and Logic Pro 8 came with a bunch. I know I had most of them uninstalled previously, but opted to add them in this time around for some current projects. Is it possible to relocate them to the second internal drive without too many headaches for Logic and Soundtrack to find them?
• iWeb creates its on hierarchy of copied media for working with my website. Is it possible to relocate this library as you would in iTunes and Aperture and just point the app to it at startup? The hold-down-option-key-at-launch method doesn't seem to prompt anything as it usually would...
• iWork '09 Trial. I've tried it, decided I like parts, but don't want to bother with it until I need some of the new presentation features. The compressed disk image download itself was fairly sizable, so I know this would clear up some more space. The problem is, I don't see an uninstaller anywhere, and its files are located in different places in the system libraries. Does anyone know of an uninstaller I missed? How about a list of all of the iWork '09 file locations?
Apple's make it "just work" mantra of software is useful, but a big disk-space hog. Things from printers we'll never use to old software that you've got the old versions still hanging around cough iWor- cough iLi- cough just don't work for power-users who use their machine as the swiss-army knife of media tools.
Also, should I be looking defragment my disk after all of these measures are taken? I'd do it for a windows machine, but i don't know enough about AFS to choose how to or even whether or not I should.
A tool like Cocktail would help clear some of the space taken over by logs and caches, but I believe that is what corrupted my disk in the first place. Please, oh thou knowledgeable forum dredgers, help me! You're my only hope...

By moving the soundtrack and logic pro loop libraries to my second internal HD, I've been able to leave an alias on the original HD pointing to them on the second drive and the applications seem to have no problem using them.

Should I delete preview files to save space on my hard drive?

Should I delete preview files to save sapce on my hard drive? At times the program crashes and I wonder whether I should get rid of these files to make more space.

PCNoviceMesa
Yes.
If you run a SD project (whether you render stills or videos) and render, you are going to get DV AVI files automatically generated. If it is a HD project, rendering deposits MPEG2.mpg files on your hard drive (whether you render stills or videos). We are talking possibly GB amounts of files if you let them pile up long enough. For Windows 7, 8, or 8.1 64 bit, these preview files are by default in Libraries/Documents/Adobe/Premiere Elements/12.0 and in the Adobe Premiere Elements Preview Files Folder there.
First let us see how much is piled up there before we take action against them.
If the preview files there are part of an existing project or projects, the consequence of deleting those files is that you will have to render again that content in the project to get the best possible preview. If the preview files represent project long since gone, good riddance.
Please check out the situation. And, then we can discuss also pile ups of conformed video and conformed audio files.
More later.

Deleted files not clearing space on my hard drive

I'm running iMovieHD v6.0.3 on an old PowerPC G5. Things have always run smoothly until now. When I started editing my most recent video, I had 191GB left on a 500GB hard drive. Whenever I deleted any clips, my trash file size went immediately to 6.73GB - 191GB Available. I edited this movie down from 45 minutes to 13 minutes and the same amount of space showed up in my trash (6.73GB) and hard drive (191GB left) as when the project began.
I thought I may just have a single corrupt/buggy session, but this is happening now in a newer iMovie session. Command+i on my hard drive still says it has 191GB of free space - after deleting almost one hour of video. All trash is empty and the deleted files seem to be gone. What is wrong?
BTW - I'm new here and not the biggest techie around, so please type slowly. Thanks.
Kevin

If any part of your edited clip remains in your iMovie project, then the discarded part also will remain, whether or not you empty the trash. As Bengt points out, this is non-destructive editing. If you discard the entire clip, so that no part of it remains in the project, then emptying the trash will free up space.
A workaround is to export to your desktop the retained portion of the edited clip to Quicktime movie, and then import the resulting Quicktime movie back into your iMovie project. That creates a new clip. You can then delete the retained portion of the old clip, and when you empty the trash it will be deleted along with the edited parts that you previously removed, and space will be freed up. You also can wait until your iMovie project is completed, then send the whole project to Quicktime and import back in. Then when you empty the trash you will free up space. Further editing will be somewhat limited, however.
Note: Whenever you permanently delete a clip, be sure that you have a back up copy somewhere on your drive if you think you might want to re-edit it or reference it in some way.

My disc space is constantly disappearing. We keep deleting files, but the space we gain keeps disappearing again. Please help.

Our disc space keeps disappearing. We keep deleting files just to keep the computer running, but the space we gain keeps disappearing. I had 10gigs of space less than a week ago, and today I have less than 1. We are not downloading anything. Whatever it is, is in the "other" category, which is currently over 113gigs and growing.

Do you use Time Machine? Have a read here:
http://pondini.org/OSX/DiskSpace.html
FWIW, having only 10 GB of space is inviting disaster - 10 - 15 GB is to be considered an absolute minimum which the OS needs to function properly; more is much better. The disk space will change dynamically as the system reads/writes to disk constantly, every time you do anything (look at a picture, edit it, type a letter, etc).

Is there a way for Itunes to scan your library to see which songs are missing the original files? I'd like to mass delete songs to save space on my hard drive.

Other than just attempting to play the song I'm not sure of any way to do it.

I have only synced a device on a single occasion in my life. Doesn't it say something about how many songs will transfer?
The laptop is supposed to be the master repository for everything on the iPod and they are designed to be in sync.
You can check the Dougscripts web site. There's all kinds of goodies there but I don't know if the extend to something like this. There's also third party software but again I don't know if it goes to that detail. People usually use it when they are trying to rescue content for a non-backed-up computer.

Start up disc is full, permenant blue screen! How can i delete files to create space?

please see above fpr my question

The issue I have is my Mac must be so full that it's not letting me do this. When I try and start in 'safe mode' it doesn't let me. All I get is a blue screen that I've left for over 30mins but does nothing apart from go into a screen saver.
I'm pretty sure I've backed up everything to an external hard drive, so I did have a thought about wipiing the computer competely and then putting everyhting back onto the Mac from the external hard drive. Just a thought but ideally I don't really want to do as I'm not sure how to do it.
Does anyone have any ideas of how I can delete documents or any ideas on what I can delete to free up some space so the Mac boots up properyl...?!?!
Help will be much appreciated!

Time capsule and time machine - permanently deleting files to make space

This may have an obvious answer - I recently bough TC and set up TM. Since TM backsups everything, what do I do if I want to delete a file forever, and never want it to be backed up in TM and take up space in TC? thanks

How are you trying to access these "old" files? That is are you trying to access them through Time Machine or directly from the Time Capsule using the Finder?

How do I access and delete file from "Save to Your Online Account" area.

I just downloaded the trial version of Acrobat XI. I created a PDF file with sensitive information that I thought would be saved only to my computer but noticed that it was saved to my "online account."
I've searched and found how to reset that feature but I need to know how to access that Online Account and remove my file permanently from it.
Any help would be greatly appreciated (and necessary if I'm to purchase this tool).

That's what it looks like to me, too. It was only saved on my computer. The reason I thought it might be saved online somewhere is because, when I saved the file, there was a box checked that said "Save To Your Online Account." What does this mean then?
Also, when I open the Acrobat application, the file is listed there under Recent Files and it doesn't give me a way to clear the recent file list.
My goal is to make sure that my sensitive information is not being stored somewhere, anywhere online with Adobe or anyone else. The only place I want that file to appear is in the documents file of my computer.

Deleted files on external hard drive...but space isn't opening up!

Hi all,
I do my Time Machine backups to an external hd. I recently tried to do a backup and it failed, telling me there was not enough space. It told me I needed 12.something GB and I only had 10.something GB available.
I checked the amount of available space on the hd, and sure enough there was about 10GB available. I deleted about 7GB of old music files (not backup files)--and when I checked available space again...it only showed the same 10GB! I deleted a little more...same thing. I was deleting files, but for some reason it wasn't creating any space on the hd.
I thought I would just try to unplug it, restart computer, re-plug it in, and go ahead and try to do a backup with Time Machine. Well, again I got the message that the backup failed due to lack of space. Same numbers--12GB needed, only 10GB available.
What the heck is going on? Why isn't deleting files creating more space on the hd? Any thoughts on this mystery? Thanks a lot!!!

Are you emptying the Trash after deleting the files? You won't free any space until you do.
No need to look for a Trash on the external; the normal Trash in the dock will do the job.

In addition to deleting files, what can I do to speed up my MacBook?

Hello!
My MacBook Pro (mid-2010 w/ 16gb of memory and 250gb hard drive) has been running really slow. I know I need to delete a ton of files as my internal disk is near full. My questions are:
My system report says the majority of disk space is being taken up by "Other". What can I delete to whittle that down?
How can I use this EtreCheck report to improve my MacBook's performance?

For information about the Other category in the Storage display, see this support article. If the Storage 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.

Startup disk full, can't get in to delete files, help!

Help!
I got the 'startup disk almost full' message so I was deleting files to make space when my computer froze, so I turned it off, now it won't let me back in again.
I get the start up chime, then it gets stuck on the apple logo with the progress bar, then a no entry symbol.
I tried starting it in Safe Mode but still can't get in.
This is very very bad, right?
I Have been using time machine to back up but I'm not sure if my most recent photos of my boy starting school last week had been backed up yet or not... I've uploaded them to facebook and instagram and had emailed them to the grandparents so they won't be totally lost but still :/
Can anyone help or am I totally screwed?!
imac was was purchased in 2009 and I *think* the last update I did was to Yosemite..

Start up holding down Command + R and then go to DiskUtility and try repairing your disk from there. As a last resort, you may need to erase or even replace your Hard Drive, but try that first. If it is not booting from there the chances are pretty good that your Drive has died.

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 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 with the largest at the top. It may take a few minutes for ODS to finish scanning.
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.
