Is it true icons and folders on your desktop get loaded into ram?

I had read on a post that leaving icons and folders on your desktop uses up Ram-memory. Is this true?

The file just takes up space in the Desktop folder on the hard drive unless it's a system element like a drive icon which resides in an invisible system component elsewhere on the hard drive. Applications typically store their custom icons in the application package itself. But regardless of where the icon is physically stored RAM is required to display the icon. So the size of the file represented by the icon is unrelated to the amount of RAM needed to display the icon. Most icons do not take up a lot of display memory. Once an icon is no longer being displayed but will be re-displayed shortly then the icon is cached on the hard drive so it can be reloaded quickly. The OS does this with everything stored in RAM if needed to free up RAM for another use. But this is not an icon thing. It has to do with memory management.

    Try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.

  • Can you convert your desktop site plan into the phone & tablet version w/o re-creating the pages?

    Can you convert your desktop site plan into the phone & tablet version without re-creating the landing pages? This seems too extensive to have to re-design each page?

    Cwsnell,
    On your nav bar there is a shorcut to other pages.
    The most effecient way I have found to do this from the phone layout,
    click on the page icon shown above
    type in the name of the page (and select the desktop version as indicated by the icon of the monitor)
    select all on that page (CTRL A / Command A) and copy (CTRL C / Command C)
    revert back to the phone layout page and paste (CTRL V / Command V)
    then resize, delete what you dont need, make any other edits and your done!
    There is not a way to copy a page entirely over.  The mobile version should have less information and less imagery to enable fast load times.

  • IMac display issues: black icons and folders, doubled up files in finder windows, programs won't update

    HELP!
    I'm hoping someone can help with my iMac 27" purchased in 2010.  From a previous discussion I started a year ago, I have had virtually nothing but trouble with it.  After the internal hard drive crashing, I was able to install OS X on an external drive and used it for a good 8 months to drive my iMac and I took it to an expert who has replaced it with a 3tb HDD, but at some point the display has gone crazy.  I am not certain if it is hardware, i.e. graphics card or video but I'll describe the symptoms and add some pics to see if anyone has seen this before and knows what the problem may be.
    1.     90% of the screen was covered with white with just a portion of the desktop showing through.
            (This happened when I tried to reinstall OS X on the old HDD and the new one, but didn't happen when using OS X install disc)
    2.     Files, folders, photos and some icons on the dock go black
    3.     Files and photos double up when in Finder.  When I'm viewing photos, it shows them but all the previous panes and the photos are jumbled behind the
            photos.
    4.     Anything I open in Preview is completely black, but ColourSync Utility opens everything fine.
    5.     Programs won't update.  They will download onto my iMac but won't update.  Some say, because I don't have OS X 10.6.8 others just won't open.
            Including Google Chrome, opens with two tabs open but when I open a third tab the rainbow wheel just turns.  Skype won't open just gives a failure
            report.
    6.     10.6.8 Update Combo downloads but when I restart the screen is covered in white - as in 1. and I have to reinstall OS X 10.6.2 to get the screen to               clear but then all the above problems continue.
    7.     Sometimes videos don't display in Youtube, or the entire page other than the video player is covered in rainbow lines.
    8.     Some buttons are blacked out on selection pages, i.e. system preferences, or saving screens
    9.     Photos opened in FB go upside down and flicker all over the page as my mouse runs over them.
    10.   Photos won't upload into internet editing programs.
    I can't find anyone who has had the same issue in all of the discussions I've looked at, but it sounds like I have a video problem, but I wondered if it might be a software problem with flash or something.  Or I have something malicious on my computer.
    I also have an iphone 5 that faulted with the iTunes and USB icons and won't fix after trying one of those R-Sims, and I wondered if somewhere along the line it may have even had a virus/trojan/malware that has infected my external drive and then my internal drive.  A reason I have thought that is because I have used my daughter's MacPro laptop and plugged in my external drive and I noticed the windows in hers were starting to do the same thing.
    And on top of all that, my fans didn't work for over a year and I had to place an external fan at the back of the computer or it would overheat and shut down, but after resetting the SMU it started working again, but it is very noisy. I have tried to download SMC Fan Control and although it downloads to the HDD, it won't open.
    Sorry its such a long post, I do hope with all of this information someone can help me.
    Thanks so much.

    HI and Welcome to Apple Discussions...
    *Soon after, I installed Quake Wars, L4D 1, 2, Mass Effect 2, Need For Speed: Undercover, Mozilla Firefox and *Sophos Enterprise AV*. Approximately a week after installation, I began to experience malfunctions varying greatly*
    Macs get grumpy when running anti virus software. Disable or completely uninstall Sophos A/V and see if that makes a difference. A/V software on a Mac will slow the drive down more and more as time goes on.
    Also, check the vendor sites for each 3rd party software you installed to make sure they are compatible with 10.6.x
    The "hard reboots" are a result of the system freezing due to incompatible or outdated software.

  • Finder changes in managing icons and folders

    I don't know if I can explain this very well but here goes. About one month ago, things changed in my Finder window when columns are selected under view. Before if I wanted to click on an icon and then after clicking on it, I could move it around to anywhere I wanted. Now after I click on it, if I try to move it, it opens. If it's a text file, that file opens. If its a folder, that folder opens. After it opens I can move it around or if I don't select it first, I can move it around but I can't move it around after I select it. I went to my other computer which has the exact same software and is also on the column view and that one still works as before. Both computers have system 10.4.11 on them.
    Has anyone heard of such a thing or know how I can correct it? It's a nuisance. If I select an icon and want to move it after I have selected it, I have to go select something else first and then put my mouse back on whatever I want to move and quickly move it.
    Thank you,
    Martha

    I just finished the test. At first it said that it found a problem and gave me the code: 4MOT/1/40000003.HDD Then it told me to shut down the computer, unplug all peripherals, and run the extended test so I did that. When it completed that test, it said no problems had been found.

  • Hard drive and folders disappered from desktop

    Having one of those days. Was working fine.  I had been working on a file in InDesign CS6. As I was saving, I noticed that the hard drive and folders had disappeared. I restarted. No luck. Have run disk utiity and restarted. So far nothing. I can still access hard drive and files, but would like them back on desktop. How can I fix that? I do have an external back up - just in case. Running - OSX 10.9.5. Help?!

    Do a backup.
    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library. Then go to Preferences/com.apple.finder.plist and com.apple.desktop.plist.  Move the .plists to your desktop.
    Re-launch Finder by restarting the computer and test. If it works okay, delete the plists from the desktop.
    If the same, return the .plists to where you got it  from, overwriting the newer one.

  • Unable to select and move and folders on the desktop.

    I was having many issues installing Adobe Premiere and that resulted in my stopping processes in the Activity Monitor & working with Disk Utility- repair Disk feature. Now I am unable to move my folders on the desktop, back them up, or move them out of the trash. I am able to open the files individually- but no dragging & dropping. I also can no longer copy & paste anything. I am running a Mac OS 10.5.8.
    Any suggestions would be appreciated. Thanks!

    First, I should have started with this, but if you have run Repair Disk, you would had to have restarted, so I didn't, but in any case, have you restarted yet?

    Please excuse my being nosy, but where on earth did you get a brand new MBP of the vintage that it would be running 10.5.8?
    I only have repair' Disk Permission's and 'Verify Dis'k Permissions options available- The 'Repair Disk' tab is grayed out.
    EDIT: That is as it should be. "Verify Disk" is not available? If it is, just run Verify, and if it's "clean," no need to run RD. If neither VD or RD is available, then:
    First check the S.M.A.R.T. status on your HD: Applications > Utilities > Disk Utility > in the panel at left, select the first item in the list/your HD mechanism > look at the bottom of the main window next to S.M.A.R.T. status and see if it says “Verified” or something more ominous like “Failing.”
    Boot from install disc (insert disc > restart > immediately hold down the c key and keep holding it until you see “Preparing Installation”) > at first screen select the language and click Continue > click on the Utilities Menu in the menu bar > select Disk Utility > select your HD in the panel on the left side (the name of the HD’s manufacturer and the model number, usually the top item in the list) > click Repair Disk at bottom of main window. Run this at least twice, and keep running it until it says “appears ok” twice in a row. If that doesn’t happen, you may need a stronger utility (such as DriveGenius, TechToolPro, DiskWarrior) or if the directory is damaged beyond repair, you may need to reinstall the OS, or you may have a damaged HD which will need to be replaced (repair utilities can only repair the directory structure, not the HD itself). When this is finished, quit Disk Utility, quit the installer, and restart. Once booted normally, go to Applications > Utilities > Disk Utility and run Repair Permissions.
    eesh. I'm afraid to reinstall the OS- I have a ton of media that hasn't been backed up yet from the past few days.
    If you have another Mac, you could boot your MBP into FireWire Target Disk Mode and copy files from it:

  • How do I correct distored icons and print on eMac desktop?

    How do I correct color distortion of icons and faded print on eMac desktop?

    Hi Dennis,
    Is this Printing from an eMac Desktop computer, or the actual display coors on the Desktop of the eMac?
    If the Latter try this.
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode).

    I looked at how to change my password but the options you told me to use were not available. I clicked on tools then options but there was no sync tab or manage accounts either.

    The login.salesforce.com website is using autocomplete=off to prevent Firefox from saving the name and password.
    You can remove autocomplete=off with a bookmarklet to make Firefox save the name and password.
