Wedding Video Via iPad

Q:

I used my iPad to shoot video of my brother’s wedding. I want to get the file into my computer, but it’s too large to email or place in my Dropbox account. Any ideas on solving my problem?

A:

You can transfer the file to a computer using the iPad’s charging/syncing cable. Just plug it into the computer and if it’s a Mac, launch iPhoto and you can use its import function to transfer the video. If it’s a modern Windows PC, a window should appear and you can use its import function to transfer the video. On a PC running the old Windows XP, you would use the Scanner and Camera Wizard. Apple has an article explaining all this.

Q:

What is the best way to transfer files from my old computer with Windows XP to my new computer with Windows 7?

A:

I’d suggest trying the built-in file transfer utility in Windows 7, called Windows Easy Transfer. It’s automated and can operate over a network, or by using USB flash drives, external hard disks or a special cable called an Easy Transfer Cable, which costs under $20.

Q:

How do you remove pictures from an iPhone? I have tried to delete them, but I have been unsuccessful.

A:

In the Photos app, in the Camera Roll, which is the main repository for pictures you take on an iPhone, there’s a trash-can icon at the lower right of the screen when you are viewing a photo. Tap it and select “Delete Photo.” The same thing works with Photo Stream, the optional feature that wirelessly syncs pictures among all your Apple devices.

To delete photos synced from a computer via a cable, you have to connect the device to the computer, de-select the albums you chose in the iTunes program and then re-sync.
