Is the file and apps will lost when upgrade to Mountain Lion?

I'm currently use lion and tend to upgrade to mountain lion. is it will affect my files and apps after upgrade to it? sorry, i'm a new user of apple product.

You mustn't lose your apps, but you have to do a backup if the upgrade fails and you can't access to OS. Also, you can check the app compatibility, but if you use Lion, you mustn't have problems with them

I have a folder and 3 files stuck on my desktop. When I drag them to the trash I am asked to enter my administrator's password. I do this but the files and folder will not delete. I have checked 'Get Info' on each of them and they are not locked?

I have an empty folder and 3 .jpg files stuck on my desktop. When I drag them to the trash I am asked to enter my administrator's password. I do this but the files and folder will not delete. I have checked 'Get Info' on each of them and they are not locked and I have full read & write access. Grateful for any assistance in solving this problem.

Back up all data.
Triple-click anywhere in the line below to select it:
ls -@Oaen De* | open -f -a TextEdit
Copy the selected text to the Clipboard (command-C).
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).
A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.
If any personal information appears in the output, anonymize before posting, but don’t remove the context.

Will updating my ipad delete all the files and apps i have there?

Will updating my ipad delete all the files and apps i have there?

Perform a complete backup before hand and all will be well. You just restore the backup after the update. If you have a backup password, be sure you haven't forgotten it. The details of what is backed up differ a bit if you are outside of the states. Read this article for details:

I am trying to import cr2files from the camera into lightroom 5 and keep getting an error message saying Lightroom can not read the files and therefore will not import them. Has anyone had a similar problem-.thanks

I am trying to import cr2files from the camera into lightroom 5 and keep getting an error message saying Lightroom can not read the files and therefore will not import them. Has anyone had a similar problem….thanks

If you are having the same problem, i.e. a disk permission problem, open your favorite search engine and search on, "change disk permissions", and I think you'll find plenty of information on how to fix the problem. This is a Lightroom forum. Your problem is with your operating system. There is no sense in rewriting instructions that are already available if you do a simple search.

Hard Drive warning when upgrading to Mountain Lion. 2 try and I was able to upgrade. Software update for IPhoto, had problems restarting. Do I need my hard drive checked

Hard Drive warning when upgrading to Mountain Lion. 2nd try and I was able to upgrade. Software update for IPhoto, had problems restarting. Do I need my hard drive checked

Yes.
Choose Apple menu > Restart. Hold down the Command (⌘) and R keys as your computer restarts.
When you see a white screen with an Apple logo in the middle, you can release the keys.
Click Disk Utility, and then click Continue.
In the list at the left, select the item you want to repair. (Be sure to select an item that’s indented to the right in the list, not an item at the far left.)
Click First Aid.
If Disk Utility tells you the disk is about to fail, back it up and replace it. You can’t repair it.
Click Repair Disk.
If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done.
Otherwise, you may need to do one of the following steps.
If Disk Utility can’t repair your disk or it reports “The underlying task reported failure,” try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall Mac OS X, and then restore your backed-up data.
If you continue to have problems with your disk, it may be physically damaged and need to be replaced

I have snow leopard 10.6.8 and want to get on iCloud which requires Lion... should I buy Lion at $29.99 now and upgrade to Mountain Lion whne available (I can't see where it is available for download yet) and what is cost of upgrade to Mountain Lion?

I have snow leopard 10.6.8 and want to get on iCloud which requires Lion... should I buy Lion at $29.99 now and upgrade to Mountain Lion when available (I can't see where it is available for download yet) and what is cost of upgrade to Mountain Lion? Or should I simply wait for Mountain Lion?

I would wait for Mountain Lion to be released. According to Apple, Mountain Lion will be released by end of July 2012.
It will cost you only $19.99 to upgrade. You can find all the details at the following link...

When upgrading to mountain lion, computer froze.

When upgrading to mountain lion, computer freezed. Hearing beep from hard drive. What should I do?

After doing what a brody suggested, try an SMC reset. The article covers when this is required, but doing this will not affect anything.
Reset SMC
If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

I had an old ipod touch. I got a new one. All of the music and apps are still on my account, but when I try to sync it the music and apps will not go on to my new ipod touch.

I had an old ipod touch. I got a new one. I still have all of the music and apps on my itunes but I cannot sync it to my new ipod.

Are you sure you have iTunes set up to synch to your new iPod? The reason I ask is that by default, iTunes will not automatically synch to a new device. You have to go to the Apps tab and click Synch Apps, and do the same for Music, PodCasts, and so on....

When upgrading to mountain lion will it delete all my files?

Will an upgrade to mountain lion delete all my files so as to lose data or will my existing files be saved?

That's the difference between doing an upgrade or a fresh install. Mac OS 10.6 or .7 can be upgraded or even reinstalled over the top of the existing OS without affecting the user folder which contains all your documents, pictures, music, etc.
In order to do a fresh install you would have to used Disk Utility to wipe the drive before you do the installation.

Lost use of word for mac 2004 when upgraded to mountain lion OSX

IVe just upgraded to Mountain Lion OSX and lost use of word for Mac 2004. how can i get in to work again

Office 2004 and Other Applications Don't Work in Lion/Mountain Lion
If you have Office 2004 which is a PPC-only suite, it will not work in Lion/Mountain Lion. You need to upgrade to Office 2011 - Mactopia - or you can try the freeware suite, Libre Office, that is functionally similar to Office 2007 for Windows except it works on Lion/Mountain Lion.
You may want to consider as well:
These two suites are similar to Libre Office but not as current or as well-supported:
NeoOffice
Open Office
And, then there is Apple's iWork suite:
Pages - word processing and layout
Keynote - presentation
Numbers - spreadsheet
Each can open and save Office compatible files. They may be purchased separately via the Mac App Store for $19.99 each.
As for other software, any PPC-based software will not run in Lion or Mountain Lion because Rosetta is no longer part of OS X. You will need to upgrade to Intel versions of the software.
(Access to the Mac App Store requires Snow Leopard 10.6.6 or higher and an Apple ID.)

I'll take a guess that review should read Preview, is that correct (If it is the answer to Eric's question is Preview)
