@Grayp:
look for a file called "ConfigDir.ini" and if it is not there then open the file called "ConfigDir_Sample.ini". before editing this file, it is best you exit Screenshot Captor. after making the changes that you wanted, save the file as "ConfigDir.ini" and start Screenshot Captor.
in any case, i am attaching a sample. take a look and modify it to suit your needs.
