When you start transferring, you should get a pop up box showing the progress of the transfer. Usually it's a meter calculated in a timer count down. (Windows). And there should also be a down hat arrow you can press to see the actual data in GB/MB of what's remaining to be transferred in a countdown scale also.

By opening the file and running the application!

You will review your flash drive to determine if all documents were downloaded

A 32GB flash drive will hold loads of photos and files. If using Windows Media Player(WMP), click on the WMP icon, when it shows on your computer screen plug your flash drive into one of your available ports on your computer. Then, click on the sync part of your WMP and it will tell you how much space is available on the drive. Locate the files you want to load onto your USB and drag them to the space in WMP that says "Sync List". As you add files it will tell you the amount of space left. When you've put all your files that fit there, click on "Start Sync" on upper left portion of sync area. It will let you know when the sync has completed and you can remove the USB flash drive. Hope this helps

Of course it will. Once you load your files on it, a little window will pop up showing the progress of the file transfers.

The computer will let you know when all photos have been completely downloaded into your USB and it will alert you if you don't have enough space to download or when it's full. A 32GB is pretty huge and holds a LOT of photos. I have placed 1000 extra large photos along with videos from my digital camera and computer into an 8GB and still have lots of room left. So imagine how much yours can hold. Hope this is helpful.

Usually the computer will say "transferred".Transfer a few pictures then try to play them back with the flash drive to see for yourself if it's transferring. That's what I usually do.

Yes it's enpugh.

It is hard to say if 32GB device can hold all your files. With modern digital cameras (and especially raw DSLR pictures) picture sizes can be pretty big. Also scanned documents can be pretty big.
Probably it would be safe to say that on average, 32GB device can hold about 8000 pictures (assuming about 4MB per picture).
The best way is to check the actual size your pictures and files (on Windows you can right click the folder and check the properties).
As for how to know when all files are copied, assuming you are using Windows, then you should see a progress bar indicating the copy progress.
Note that you should make sure to safely remove the device to prevent loss of information.

It really depends on the operating system of the computer you are using, but most are pretty similar. In windows you would see your flash drive as a drive after plugging it in, and then you can copy/paste or drag/drop files onto the drive. There will then be a dialog box that comes up that shows progress of the transfer, that will disappear once the transfer is complete. On OS X the drive will show up in your finder and the process for copying files is the same as windows.

32GB should hold quite a bit of pictures. You could put any files including video's though videos will take up a lot more space obviously.

Yes, there shouldn't be a reason it won't be.

Yes, If your computer is fitted with a USB 2.0 port, and you are using Windows 7, Windows 8 or Windows 10

Yes. USB Flash Drives are compatible with any computer. It's the way it's formatted that may cause it to not initially work on a device, but you can just reformat it.

Yes it should be compatible with any computer with USB ports and a compatible operating system.

Yes they can be, I have used them with my HP products-computer and printers before without any trouble.

Yes, it should be compatible with any computer with a usb drive and running any Windows, Linux or Apple computer systems

I am using an HP Pavillion Computer; works well.

You don't need to worry about compatibility with SanDisk and PNY USBs if you have a Microsoft system, however if you are planing on using it with a MAC system, you should check the product Specifications, they always include wether it's compatible with MAC or not. (this one IS compatible with MAC too.)

YES I HAVE AN HP COMPAQ COMPUTER AND USE THEM CONSTANTLY TO CARRY DOCUMENTS BETWEEN HOME AND WORK COMPUTERS.

yes you can read / write

I copy files to it into custom created directories to share photos/ tranport to the local camera store and for prints/enlargments.
When done erase the files and do it all over again.

Great for sharing files with computers not on the same network/lack of ability to email large files.

Enjoy,

Rewritable

It is re-writable.

This and all thumb drive like it, are able to be written over and over again.

Both

All USB's are rewritable. No, there isn't a function where you set as read-only; thats done on the software side if you decide to total encrypt or allow "guest" users to only copy down but not mess with the contents.
