Delete files from startup disk?

Under system preferences I see the StartUp Disk, but where do I delete files from that in order to clear up some space?
I have MacBook Air OS 10.6.8. Is it just under my User? everything like applications and documents, etc?

Open Finder and look on the sidebar for the House Icon:
Click on it and you should see a list similar to this:
You should be able to delete any items in those folders to create the required space.
You may also delete any third party applications from your Applications folder.
Ciao.

Hello Smile_333
The article below will assist with finding things and help increase the hard drive space for your computer. The best way is to have an external hard drive to copy things to if you do not want to delete and loose things.

Deleted files from USB Disk attached to Airport Extreme

I deleted files from a USB disk attached to my airport extreme. I then needed to recover them but they are not in the trash can...how can I find and restore these files? I have not emptied the trash. I am just looking in the trash in my bar at the bottom bar. I got the message that asked if I wanted to send them to the trash and I said yes...help, I need the files!
Thanks,
Josh

Unfortunately, as the message clearly states.....the file(s) will be deleted immediately....not moved to the trash.
If you want to experiment, a utility like Disk Warrior might be able to salvage some of the data on the disk....IF....you have not made any changes on the disk since you deleted the files.

But, it will be much quicker to simply restore a copy of the file(s) from your backups.

How do i delete items from startup disk

how do i delete items from startup disk

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!

Delete file from hard disk etc.?

Can iTunes do the following, and how?
1. When I ask a file to be deleted from the Library, is there some way of asking for the file to be deleted from the hard disk itself?
2. If the location of the file has changed, can iTunes update its library and delete the unfound files from its list?

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Cannot delete files from hard disk (after deleting from playlists)!

all of a sudden itunes stopped allowing me to automatically delete (with the warning) a downloaded podcast so I would have to go to the hard disk manually to delte the posdcast.
How do I get the system back to what it was where I delete a podcast and then get the warning and say ok to delete from hard disk?
TIA!

Hi Chris:
2 part response:
I founf the problem--somehow my itunes folder was moved to a different part of my hard drive--once I moved it back I can delete.
I can delete as follows: when I right click and click on delete, I first delete the file from itunes library--then I get prompted if I want to delete from my hard disk by sending file to recycle bin--There is also a prompt if I do not want to see the warning--which I have on as a safety precaution. So I bet the default could remove from playlist and send file to recycle bin in one move.

How to recover Deleted file from HARD DISK

By mistake my entire AVCHD file of 90 Mts duration was deleted from my Hard Disk, this I realised after a week., in the meantime I have not added or deleted any file from this hard Disk. I had given my this hard disk to my service engineer to recover the video., he has tried and recover some 40 mb file., but I cant open this recovered video file in Premiere or any other video convertor programme., also I cant get any information about Video.
Can anybody in the forum help me and suggest how to recover my deleted Video from the Hard disk

Hi, hard disk data loss is actually a hard task for many users 'cause most of them think this kind of problems is a complicated situation. Here are some tips you need to know after data loss happened.
1. If you meet the file loss situation, keep calm and stop using your computer to do any read or write operation until you find the way to recover the lost files because any wrong operation.
2. If you've lost a file, time is of the essence. As new files saved to Mac hard drive or storage devices, the original files gets overwritten. So do not use the drive or disk which your deleted files are stored before at all, until you have completed the scanning and recovery process.
3. The system crashed or the files loss situation happens occasionally, so remember build a backup for the files periodically is strongly needed.
4. If you meet the file loss situation again, stop using the Mac or storage device right now, use another computer to process the files recovery.
5. Remember this, no matter at the normal time or after files recovery, build a backup for the files periodically is the best method to protect your files from data loss situation.

Mini telling me to delete files on startup disk

A screen started popping up last night telling me to close all my applications to create more space and that I needed to delete files off of my startup disk because it is too full. I'm not sure what files to delete, and/or, if I should even pay attention to this notice.... Help!
Also, I was only running Safari when the notice came up. It happened twice last night and once this morning.

If your computer is locking up and if you have been running out of room on your hard drive, you should make sure your hard drive has not suffered some corruption by running Utilities > DiskUtility and verifying the hard drive.
BTW you should try to keep 10% of your hard drive free space, for better performance. And if you can't do that, at least keep 2 Gigbytes or more free. (OSX gets very unhappy when it runs out of room -- and bad things start to happen.)

Msg states: "your Mac os x startup disk has no more space available for application memory...Removing files from startup disk may help." yet, I have 299.11GB of 319.73GB available. Why is msg received?

The full message reads as, "

Why am I receiving this message and being forced to force quit items? Both times the message has been received, Safari was open (frozen) while checking yahoo! mail.
I received my MacBook Pro as a gift less than a month ago and I have only saved 20 pictures within iPhoto and installed Skype and Vuze...no other modifications from default have been made.
Any idea?

Have Photoshop catalog on computer but deleted files from referenced disk

I recentely started using photoshop elements 7 and assumed it gathered the photos similar to earlier versions. Thus, I thought the browser was uploading my pictures to to a folder on my computer, when I clicked on upload.I assumed the pictures would be saved in my documents/pictures/... as previous versions did. But apparently it did not and my card was reformatted after this process so the pictures are not available. However, my catalog is available with all the pictures in it. If I try to edit the picture from my catalog, I can't, because the program is trying to reference the original picture. My question is, Is there anyway I can manipulate the pictures in my catalog in a way that will allow me to edit them, without having the original pictures. If I click on skip the process of accessing the original nothing happens.

Windows Vista, and Windows 7 have System Restore which you could run in an attempt to recover files deleted from the recycle bin. Mac OSX has TimeMachine.
Vista & 7 have an improved System Restore Program. I’m not sure XP has the same capabilities.
The program was not really designed for this purpose and you should back up any recent files before reverting to an earlier restore point.

Lightroom version 4 won't delete files from external disk

I've searched here and found several people getting this failure and just want to add that I'm having the same problem. I have the latest everything, full stop ... I get the prompts and nothing happens in the end. The photo stays in the catalog. I have resorted to removing them from the catalogue, but they're staying on disk.

I had this problem as well with 4.0 and had to resort to launching LR as an "Administrator" on my Win 7 PC. I just noticed that it is back after the upgrade to 4.1 since it reset me back to a normal launch. I guess I will have to set it back up to run as Administrator again.

Where can I find the Start up disk and how can I delete file from it.

where can I find the Start up disk on theMac Book Air?
How can I delete files from it?

The startup disk is the internal SSD in your MBA. You may delete files by draging the file to Trash (or clicking on them and then execute COMMAND+Delete). Then empty Trash.
Ciao.

My start up disk is full. How do I delete files from this?

My air is saying my start up disk is full. How do I delete files from it? Is there a specific location I'm supposed to delete from, or is it just general files from everywhere--email, etc.

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. 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 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 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.
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. Type carefully and then press return. 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.
When you're done with the app, quit it and also quit Terminal.

How to delete files from start up disk

Please help. After my macbook air is on for 2-5 mins, it comes up with I need to delete files from my start up disk. I went into start up disk and the only thing in there is the OS X system. So, then a small box appears. and tells me my memory is full and that I need to force quit applications. Sometimes the only application that is on it is finder. At this point the macbook air then freezes and I have to turn it off holding the button down. When I go to turn it back on it will often not turn back on. This laptop is only 11months old and running the new OS X system (mountain Lion) that just came out.

Use Grandperspective to visually map all files:
