CHK file

Hi,
First I would like to say that I find the software excellent! It is intuitive and have had no problems.
I am having a problem with some of my pictures, but am unsure if it is due to the cam2pc software or something else as this has never happened before.
The folder in which I hold my photos suddenly has been renamed to FOUND.000 and FOUND.001 and moved to another location in my directory.
When I found these files, all the photos have the CHK extension. In windows explorer and in the thumbnail view, the photos cannot be viewed until I double click on them. I associated the pictures with cam2pc and am running windows 2000 professional.
Does anyone know how I can save these pictures? or convert them back to jpg? I would like to convert them back and burn them to a CD but am worried about losing them.
I would appreciate any help!!
