I need to replace automated file names generated by a digital camera with something else. For example, replace 'DSCF0001.JPG' by 'Hawaii001.JPG'. I am familiar with Explorer's ability to generate a numbered series of such names but if you do this you loose the ability to sort by date of taken photo. I want to merge jpg's from two different digicameras and sort by date of taken photo. If the two folders of jpg's have different sets of names I should be able to merge and sort as I wish. Thus the need to run a search/replace operation in Explorer.
