Renamer is a very easy to use application with which you will be able to change the name of your files and folders with no matter, because the program runs as if it were a Windows Explorer, allowing you to navigate through folders, choosing the one where the files you want to rename are.
Once you have selected the folder, we will see in two columns the initial and final aspect that the file will have after making changes. In addition we will be able to manually add the modifications we want or if we prefer, to automatically change them.
One of those features is the one which allows us to automatically change all files and turn them into capital letters or lower-case, put a letter instead of other,.
Thanks to Renamer, in a few minutes, we will have in order all those files we had disordered in our computer.
