One option available to you when transfering files is to automatically fill some EXIF fields on-the-fly. This allow you to make sure that all your pictures do have some mandatory information in them. Currently supported EXIF fields are Artist and Copyright.
Simply check the boxes you want to fill and enter the text you want cam2pc to put and that's all!
In some cases you might want cam2pc to not download some files from your camera. For instance, some cameras save their configuration on the memory card and you may not want to get those files. You can specify as many wildcards as you want to tell cam2pc which files should not be downloaded.
If you want to exclude some files by their extension you can specify *.ctg as the exclusion mask (replace of course ctg by the extension of your choice).
If you want to exclude a whole directory, specify *\cfg\*.* as the exclusion mask (replace of course ctg by the directory name of your choice).
