XBIN files are associated with the RegSupreme registry cleaning software from Macecraft Software. It's unclear how an XBIN file is used by RegSupreme; it might be an encrypted file used for verifying user registration, or it could be a file you download from the company to authenticate your purchase. Most XBIN files used with RegSupreme are probably called license_backup.xbin or data.xbin. eXtended BIN files are called XBIN files as well, but they end in the XB file extension. XBin, or eXtended Binary, is also a file format unrelated to XBIN files. andriano_cz / Getty Images How to Open an XBIN File XBIN files are license files are used by Macecraft Software's RegSupreme program. You might be able to open the XBIN file by using the software's File menu, but it's also possible that the program uses XBIN files automatically. In other words, the XBIN file might exist in the program's installation directory and used by the program as needed, so you might not be able to open it manually. If you find that an application on your PC does try to open the XBIN file but it's the wrong application or if you would rather have another installed program open XBIN files, see our How to Change the Default Program for a Specific File Extension guide for making that change in Windows. How to Convert an XBIN File Given that XBIN files are related to a license, it's unlikely that there's a method or reason to convert one to any other format. Most files are converted to other formats with a file converter tool, but again, there's probably little reason to convert an XBIN file. Changing the format would make it unusable in RegSupreme.
