AIT files hold the different components of an Adobe Illustrator drawing, including the images, settings, and layout, and are useful when working with projects that should have a similar, pre-formatted design, like brochures, business cards, etc. Creating an AIT file is done through Adobe Illustrator's File > Save as Template... menu option. How to Open an AIT File Adobe Illustrator will, of course, open AIT files. Some people have had luck using CorelDRAW to open AIT files using the Import function in that program, but I haven't tried it myself. If Adobe Illustrator isn't opening your AIT file, you might want to check that you're reading the file extension correctly. Many file extensions look incredibly similar, but that doesn't mean they can open with the same programs. AIR, ITL, AIFF/AIF/AIFC, ATI (Office Accounting Updated Company), and ALT (Dynamics AX Temporary) files are a few examples. If you still can't get your AIT file to open, it's possible that it's in a format that has nothing at all to do with Adobe Illustrator. If you think this might be the case, try opening it as a text file with a free text editor. Most formats, even if they're not text-based, have something readable that can help identify what type of file it is. How to Save an AIT File The benefit to an AIT file is that when opened, Adobe Illustrator makes a copy of it so that you're not editing the original, and therefore not overwriting the template file with new information. In other words, when you open an AIT file, make changes, and then go to save it, you'll be prompted to save it somewhere as an AI file, not an AIT file. Saving the file in the AI format is a good thing because it's the whole point of an AIT file - to provide a similar building block for creating AI files. Of course, this also means that you can't make changes to an AIT file as quickly as you can with an AI file. That said, if you do want to edit the template file, you can save it as a new file but then choose the AIT file extension instead of AI, overwriting the existing AIT file. Another option would be to use the File > Save as Template... option instead of the regular Save As... menu. How to Convert an AIT File When you open an AIT file in Adobe Illustrator, you can save the file to a new format with the File > Save As... menu. Some of the supported formats include AI, FXG, PDF, EPS, and SVG. You can also export the AIT file to a DWG, DXF, BMP, EMF, SWF, JPG, PCT, PSD, PNG, TGA, TXT, TIF, or WMF file using Adobe Illustrator's File Export... menu.
