Your favourite graphics program saves your files with a .GIF extension, and your web pages link to .gif files. And you've just done a batch conversion of 30 product shots ready to ftp to the server. Your designer uses a Mac and saves everything in upper case. Your web server is case sensitive, and you don't want to use upper case. CaseTool couldn't be easier to use. Simply select the files you wish to convert, drag 'n' drop them onto CaseTool and voila! Their names are converted! Want to convert from UPPER to lower? Right-click on CaseTool and the conversion direction is reversed!
