Free extension software for mac

Extension Toy is a small AppleScript which enables you to hide or show file extensions in a specified folder.
If the selection contains a mix of hidden and visible extensions, it asks you to choose whether to show or hide them.

Very useful to figure out whether youve added an extension to a filename or not... or just to keep things tidy. Go play!

Extensionator 1.0 brings you convenience of using a small utility which adds the appropiate DOS/Windows file extension on Mac files. Just drag a file into the Extensionator window and it automatically adds the file extension.

Requirements:

• PPCMac OS 8 or higher
  

Extension Wizard helps solve the problem of not being able to open documents or email text attachments that your download from the internet.

Whats it for?
As you begin to use your IMS computers you will probably want to transfer documents created on your Macintosh to your IMS network folder. If your file name does not include the correct three-letter file extension then your IMS computer may not know which application to use to open the file. That means you will have to select the correct application each time you open a transferred file. You can add the correct file extension for each file manually if you want to. Not a big deal for a handful of documents. But could be a real chore if you have lots and lots of files. Or you can just let this magic little application do it for you.

How does it work?
Magic of course! Just select a list of files you want to convert and drop them on the magic hat icon. Then watch it perform.
It auto-magically checks the file type and adds the correct file extension to the file name. Because some operating systems cant handle file names longer than 31 characters, it will also truncate the file name to 27 characters (the dot and the three-letter extension make it 31).
If the new 31 character file name is already used a dialog box will appear asking you to select a different name. If the name you select is already in use then the operation will stop. You will have to check your files and try again with any files that were not already converted.

What files does it convert?
It will currently work with Microsoft Word, Excel and PowerPoint documents; AppleWorks documents and FileMaker Pro documents. All other files will be ignored. If you have a lot of documents from another application, let me know and I will add them to the list and send you an update.

Requirements:
MacOS 9.0 or later.
