I have a memory card in and when I go to look t pictures it's says file error?

can have different causes. To many pictures on the memory card card is full. From the last picture file name ends with 999 or 9999.
Or there was an error while writing a picture to the memory card, caused by a power failure.
I would put the card in an external memory card reader and try to put all pictures in a folder on the computer. Then format the card FAT 32 or FAT 16 and then put it back in the camera. When switched on, first format the card again, in the camera, to make sure the camera can work with the card and the format.
Success.

And you think that is the only problem?
The first thing I should try, is remove the memory card and read it on my computer. Use an external card reader.
If the card still holds pictures, reinsert the memory card and try again.
I don't know if the camera was on, while you dropped it. Because if on the right moment the camera was still writing to the memory it hit the floor, the complete file system can be corrupted.
If you can't read pictures on the external card reader, you should first try to recover all the pictures, because there is a reasonable chance, the pictures cam be recovered, even if the file system is corrupted.
Some errors on memory cards or pictures can be corrected with some recovery programmes, but not every error can be corrected. free software to recover your files on a memory card:

If there are no important pictures, or no pictures at all on the card, you can skip the recover part. Just format the card with FAT 32. When placed back in the camera, do a format with the camera.

Success. I hope this is all damage on your camera, but ????

Sometimes files become corrupted. There can be hundreds of reasons. Your memory card, how small is a very complicated piece of electronics. Being a picture on a memory card is very scary. One error, just a spark of electric discharge, could damage the card, a part of the card or just some bytes on the card. Sometimes the errors consist of changing a 1 in a zero or a zero into a one, without physical damage to the memory card at all. So when the card should be formatted again, it could be you don't find any error again.

For that reason it is important you do put your pictures on a computer and from there make a backup. Never leave your important pictures on a memory card for the life of the camera.

try using a memory card with 2GB or below
the camera might be having some problems reading the 4GB that you have

if you connect the camera to your computer and file error still appears that means that the memory card is corrupted and you really need to format it

before you do make sure that you have a copy of the files saved in the memory card

*formatting the memory card will delete all the files saved in it

go to MENU> SET UP > FORMAT

copy all the pictures/files saved in your memory card to your PC then format the card, you can format the card by going to MENU > SET UP > FORMAT

Hi, It might be time for a new memory card. A last effort you can try is to remove the memory card and insert it into a memory card reader connected to a PC. There are diagnostics and utilities that can be performed on your memory card since it will be treated by your PC as a removable storage. You can format the memory card, run diagnostics like Norton Disc Doctor or similar. If in any test an error shows, then you have just confirmed that is due for replacement. If after formating, scanning and checking it shows good, then you can try using it again. You can also try cleaning the little gold tips at the end of one side of the memory. Hope this be of some help/idea. Post back how things turned up or should you need further information. Good luck and kind regards.

This error message means that there is no memory card in the camera. Pictures were not copied. Turn off the camera, and then insert a memory card.
