I discovered this little application a while ago called ‘namechanger’. It allows you to automatically change the name of a large number of files in one go. It has lots of options. You can add something to the start of filenames or to the end. You can do search and replace of filenames. You can remove characters, add in a date or add in a sequence of numbers. It’s very handy. You can download it from here: https://mrrsoftware.com/namechanger/
Tab Launcher is a great little app that sits on the side or top of your screen. It’s like a manilla folder where you can put commonly used files. It makes accessing them much quicker. The great thing is you don’t have to actually move the files into tab launcher. Your files stay exactly where they are but this is an easy way to access them.
This is the top of a Finder window. Those icons along the top are called the toolbar. I find it really handy to put items that you use a lot into this toolbar so that they are available from every Finder window.
