Can we scan to a folder on a pc or directly in to an online storage like dropbox?

The answer to your problem is to make a different folder outside of your current Dropbox folder. Name it anything you like, then move all of your current Dropbox contents to the newly created folder. Once you do that, completely uninstall the Dropbox program. Restart your system. Download Dropbox from its official website, have it reinstalled. Move back all of your files back to the Dropbox folder :). That's it. If in any case you still have a problem after you've done everything I just said, try to uninstall Teamviewer if you have it, then restart your PC. Now you can check, if everything is working fine, then you can reinstall Teamviewer as well. Good luck.

Strongvault Online has horrible reviews, and many users say it contains spyware and 'tracking' viruses. I recommend not using it. Dropbox is a reliable, trusted and safe free alternative. If you need more than Dropbox's 'free' limit, try Gmail. If you open a Gmail account from Google, you also get 15 GB of free storage right in your email account. Carbonite is a good, inexpensive backup as well.

There's several things that could be the cause here. I'm going to assume that you're plugging the tablet into the PCs USB port with the standard charging/data cable that came with your tablet.

Easy Solutions:

1. You might have a bad cable. Try a different cable, if you have one.
2. Your USB port might be bad - try plugging into a different USB port. If you're plugged into the front of the PC, try the ones on the back. Also try plugging a different device into the USB port that you were having trouble with - does the other device work in that port? If so, your USB port is OK.
3. Go into the Settings app on your tablet. Select Storage and tap the menu (three dots in the upper right corner). Select USB Computer Connection from the menu. There will be two choices here: Media Device (MTP) and Camera (PTP). Try unchecking whatever one is checked and checking the other one. Unplug your tablet and plug it back into the PC.

More Challenging Solutions:

1. You might not have the proper drivers for your PC to recognize your tablet. Samsung makes a software package for your PC to communicate with your PC called Kies. You can download Kies here: http://www.samsung.com/us/kies/ Download it and install it. Then plug your tablet into your PC and it should find it.
2. There are other ways to transfer files between your PC and your tablet, some of them are really easy, some not so much. The easiest is the Dropbox app. Download the app from the Google Play store - it is free. Create a free account and sign in. Then on your PC go to www.dropbox.com and download their free Windows program. Install it and sign in with the same account info that you used on your tablet. This creates a shared space out on the Internet. Anything that you put in your dropbox folder will automatically get put in your dropbox folder on your PC. On your tablet you can look at what is in the dropbox folder and choose whether or not you want to copy it to your tablet. You can also upload files from your tablet to the dropbox folder (automatically putting them on your PC).
3. Another way to transfer things between your tablet and your PC is the AirDroid app. You can download it from the Google Play store - it is free. When you use it on your tablet, it will give you a web address on your local WiFi. Go over to your PC and open a browser, go to that address and you can communicate directly with your tablet over WiFi. You can copy files, add and delete thigns, and all sorts of other functions. AirDroid is very useful.

Which cloud storage service you are using? In some cases Google Drive can take your files directly to his storage on cloud. Happened before to me. If this is the case just download the files to your storage somewhere different.

Do you have iTunes? Take a look at this Apple forum: https://discussions.apple.com/thread/1406326?threadID=1406326&tstart=0 AND: http://forums.macrumors.com/showthread.php?t=438970

Hi there - if you don't want to use a cable, my favourite solution is using free storage services like Dropbox or Sugarsync. They've got apps for most of the modern mobiles. If you do not have an account in one of those - you can use this links to create one, it's free (You don't have to use this links, but by using them you will give me some more free space on them. If You don't want to - just google them :D):
Sugarsync
Dropbox
When You have an account and installed a proper mobile app You just have to put your music files into a synchronised folder. It's always Dropbox folder for Dropbox and in Sugaresync you've got some predefined folders (like Magic Briefcase) and you can set as many sync folders as You want. Once your file is there You can get it by using your mobile app to download it to your phone. I use Sugarsync and Droper apps for Symbian.
If you will put your favourite collection of songs into sync folder - You will have an access to it everywhere. You will just need an internet connection and a computer or smartphone.

It depends on what you need to do. If you want the files to be public so anyone can access the files, follow the directions in the Public folder (http://dl.dropbox.com/u/6448282/How%20to%20use%20the%20Public%20folder.rtf). If you only want to share the files with certain people, follow these directions: http://www.grovo.com/dropbox/sharing.
Hope this helps!

You can try logmein (logmein.com) or Go To My PC (gotomypc.com), which allow you to remotely access your desktop as though you were using it directly. Not sure if it is compatible with an older machine like the original iMac, depending on what OS you are running on it.
Alternately, you could use something like Dropbox to share files between the two, if that is what you are really after. Dropbox (dropbox.com) keeps a copy of your files in a secure folder online, which can be accessed from many computers, and is kept in sync automatically.
