Ever wondered why the list of different filetypes is so exhaustive?
It all starts with the software company’s desire to make the consumer dependable on their product. Take Photoshop PSD files. These files are created in the software by Adobe and enable to option to edit the layers of a project after saving. This automatically implicates that the user has to use Photoshop the next time he wants to continue or edit the project. But this also adds the necassity for other purchases, were the PSD file to be sent to another person. They would only be able to open the project file with Photoshop.
But why so many? Why does Microsoft Excel product XLS, XLSX, CSV and many more. Again, same reason: commercial purposes. Yes, of course the XLSX version has some compatibilities that are not available in the XLS version, but the main purpose is the repurchase of the Microsoft Excel project. Since the updated version (where XLSX format made his appearance) is backwards compatible with the older versions, but not the other way around, the consumer is eventually “forced” to purchase the updated version as everyone around him (especially in school or business markets) are starting to send in XLSX formats.
And so, almost every single utility produces their own special kind of output format. A big thank you to all the converter sites and software that can be found on our site. They make the world a bit easier in their own way!
