The 160KB you see on the memory card is just a base menu or something that formatting installed. It's not photos... Those will be much larger (megabytes/millions of bytes instead of kilobytes/thousands of bytes).

Hopefully you formatted the card in the camera (not in your computer). That's always best. It insures the right file structure has been set up.

P.S. I see someone else got the right info... FAT (File Allocation Table).

For several reasons, it's best to remove the memory card from the camera and use a card reader to transfer images to your computer.

You actually don't need any fancy software to transfer the images to your computer. As soon as you insert the card in a reader, it will look like another hard drive has been installed.

First a folder on your computer to receive the images. Then navigate to the memory card and look inside with your computer's operating system (Explorer on a Windows machine). Look for a folder called "DCIM" on the memory card. That contains all your images, probably inside another sub-folder (there may be multiple sub-folders, the camera will create a new one after each 9999 images it takes). Open that, click on any single image to highlight it, then use "select all" (ctrl "a" in a Windows computer). Once all are selected, simply drag and drop to the folder you created earlier to receive them.

If you left click the drag & drop, it will "copy" the images... if you right click the drag & drop it will give you a menu with other choices. I'd recommend always using "copy". The reason is this leaves the originals on your memory card for now. "Move" would remove them and if anything happens to them during the transfer to your computer, you'll lose them completely. So always be sure to "copy".

Once the images have been safely copied to your computer, you can format the memory card any time in your camera and that will allow the old images to be overwritten (doesn't actually erase them). I usually just leave images on my cards until the next time I use them, then every time I put a card in my camera I format it. I also like to backup my images right away, don't trust them to a single location on a computer. "Stuff happens!"

Right, my definition of Manual is the same as yours. And I have little to none experience shooting in that mode. I've taken pictures of family and landscapes all my life and gotten very good even many exceptional outdoor images. However I'm now trying to re-train to be a Real Estate Photographer. So I've definitely got a heavy learning curve to get through. I'm trying to find a local tutor to help with that. I realize the questions I've asked here are not on your level of expertise. So I'm taking one of the suggestions to find a local photo group to join. At the time this seemed to be the only resourse I'd found to possibly get some answers. I really appreaciate all the responses and helpful advise I've received here, even though my questions were confusing in the way I tried to ask them and mis-spellings. So Thanks very much Monica
