What is a .ITF file?
An ITF file is a special kind of data file that is made by a program called Glorylogic Image Tuner. This program is something you can download for free and use to change lots of pictures all at once. For example, you can make them all smaller or bigger, add a watermark (which is like a stamp to show who owns the picture), change their format (like from a JPEG to a PNG), and do other cool stuff like making them sharper or changing their colors.
When you use Image Tuner to work on a bunch of pictures, you can make a list of all these pictures in the program. This list will have important details about each picture, like its name, how big it is, what type it is (like if it's a JPEG or PNG), and where it's saved on your computer. Once you have your list ready and decide to save it, Image Tuner will save this list as an ITF file. This ITF file doesn't contain the actual pictures but information about them and where to find them.
To open an ITF file, you need to use the Glorylogic Image Tuner program. This is the program that knows how to read the ITF file and understand the information inside it.
If you want to make an ITF file yourself, you start by opening the Image Tuner program, then you go to the File menu and choose New. After that, you can add all the pictures you want to work on to the program. When you're done, you go back to the File menu, but this time you choose Save as to save your list of pictures as an ITF file.
So, in simple terms, an ITF file is like a to-do list for pictures that you want to edit with Image Tuner, and you need Image Tuner to open and work with this list.
