Will updating to Mountain Lion delete files?

I updated one Mac and a folder full of files on my desktop was deleted in the installation of Mountain Lion. Was this user error or will it happen again?

Welcome to the Apple Support Communities
You won't lose data but you must make a backup because things like losing folders can happen during the Mac OS X upgrade. I recommend you to buy an external drive, create two volumes on it and use one for Time Machine and the other for Carbon Copy Cloner

Will upgrading to Mountain Lion delete MS Office?

I have MS Office installed on Lion OSX and I am really worried about what will happen once I upgrade to Mountain Lion. Will I lose the installation? Will I have to reinstall from the disc? Or will office survive the upgrade and appear in Mountain Lion? I lost my disc a long time ago. I have a 2011 MacBook Pro.

Yes it is compatible so with will not delete it or render it unusable.
See this article to make sure you have 2008 or later.

Will updating to mountain lion wipe my computer

Will updating my software delete all my data on the computer?

Don't. Install clean OS on another drive instead, you've got four drive bays use 'em.
Then use Setup Assistant and leave the OLD system AS IS as backup and dual boot until you are sure, that will be your "what if ML doesn't work" for you.
Never to me a good idea to "update." Clone first if you must (don't rely on TimeMachine, rely on a working bootable backup instead).

Will upgrading to mountain lion delete any of my programs?

i currently run lion..will all my files, apps, downloads, etc be intact after the upgrade?

Yes, they should not be distrubed. However, it's always wise to have a backup.

Will updating to mountain lion negatively affect my air?

YES.
Do NOT install this garbage on your Macbook Air.
it will shorten your battery life, randomly lock up on you, and remove functionality.

Will upgrading to a new OS like Lion or Mountain Lion delete my previous files on my computer? Will I have to back up my files with a hard drive first?

Upgrades do not delete your personal files in the Home folder. But any installation can go bad, so it would be wise to backup your current system to an external hard drive.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later

Will uploading Mountain Lion Delete my files or do I have to back up my files first?

Yes; having your backups on the same drive as the original data won't help when that drive fails.

I am considering updating to Mountain Lion. Have checked the website Roar for compatibility with other software; some OK; some have yet to be tested. When will that testing be done?

I am considering updating to Mountain Lion. Have checked the Roar website for compatability with my existing software; some are OK, but Bridge and Picasa said to yet be tested for compatability. When will this happen?

Will I need to update from Mountain Lion (10.8.4) to Mavericks prior to the Yosemite rollout this fall?

I am running Mountain Lion (10.8.4) currently. I rolled back to Mountain Lion from Mavericks back in October 2013 because I was having problems with it. However, I've heard there are improvements to Maverick since my initial install. My question is will I need to update from Mountain Lion to Maverick in order to update to Yosemite this fall? Thanks in advance.

If your goal is to install Yosemite upon its release, I doubt you will need to do it from Mavericks.
If Mountain Lion does not have features you need and Yosemite will, then, as WZZZ suggest, give Yosemite a chance to have any bugs worked out first.
If your concern is security, Mavericks is the current OS but Apple is still providing Security Updates for Lion, so Mountain Lion should still be good to go for a while yet.

Currently running OS 10.6.8. If I update to Mountain Lion will Photoshop CS6 and Lightroom 4 still work?

Can't say anything about Lightroom, but Adobe officially supports CS6 all the way through Mountain Lion.

HT1338 How do I get a driver for my Epson Stylus Photo 1400 so that it will run with Mountain LIon? I tried "Software Update" and says "no update available"

How do I get a driver for my Epson Stylus Photo 1400 so that it will run with Mountain LIon? I tried "Software Update" and says "no update available". I contacted Epson and was told all driver updates had to be obtained using "Software Update"?

You will find the latest Epson drivers herehttp://support.apple.com/kb/DL1398.
If you don't find a driver for your printer in the above, then install the Gutenprint drivers. It supports your model.

When I update to Mountain Lion, will I still be able to run iWeb?

When I update to Mountain Lion later this month, will I still be able to run iWeb?

Here is some info on MobileMe and the role it plays re. iCloud and iWeb - it appears you can keep using iWeb with another web hosting service (scroll down):

@ macintosh290:
MobileMe ceased to exist on June 30th.

Will Mountain Lion delete iWeb?

Considering upgrade to Mountain Lion, do not want to lose the iWeb package that was shipped with my iMac when I bought it mid July 2011. Does anyone know for sure if Mountain Lion deletes iWeb on install? Thank you.

I ran across a "hack" that will let one run Front Row with Lion:
Ralph Perdomo reports that he has ported OS X Front Row to Lion by moving several frameworks and the application itself from his old Snow Leopard install. He wrote up the procedure over on his weblog and has provided an optional installer for anyone who didn't keep a Snow Leopard install around.
Perdomo reports that the re-installed application seems to work well, and he does not seem to have run into conflicts from what I can tell. The frameworks/app in question are:
/System/Library/CoreServices/Front Row.app
/System/Library/PrivateFrameworks/BackRow.framework
/System/Library/PrivateFrameworks/iPhotoAccess.framework
/System/Library/LaunchAgents/com.apple.RemoteUI.plist
/Applications/Front Row.app (Front Row 2 in folder)
TUAW has not had a chance to test this hack out, but we applaud Perdomo for his creativity in the face of OS upgrades.
I haven't tried it either so can't confirm or deny that it works.

I have iOS 10.7.5 and if i update to Mountain lion 10.8.2 will i lose all my old applications i've purchased and other software i've downloaded? and what is time machine ?

No. You will not lose any of the applications and data will be safe.
But make sure that you have working backup. This is very important.
Time Machine is the built-in backup software/application.
Best.
