No, you can't import any file into Easy Barcode Generator because it doesn't have the necessary features to do so. I've downloaded and installed it, then checked the available functions and buttons. There is no way to import or backup from restored files. The software is used only for creation and saving and that's it. I've visited their support website and it's pretty vague in terms of files and documentation for the software.
Additionally, if you want to reach customer support, it's possible through the email available on the support page.
