An XAPK file is an Android application installation file that includes the APK file plus some extra files, known as OBB expansion data files, which are essential for functioning. These OBB files are usually downloaded once the app has been installed, but in some cases it is good to have them earlier, and they are usually cache data, additional information, data bases, user game maps or information… It is an alternative, unofficial, executable file, and if you try to install them normally by clicking on them you will just get an error message - the operating system’s default installer doesn’t recognize them and therefore does not allow you to open or run them.
They are for installing and distributing Android applications, with the difference that they already include everything needed for the app to function. Apps and games can be installed with them. They are usually much larger than normal APK files due to their content. With regard to security, you need to take certain precautions. This kind of file is not available in the Google Play Store, but can be found in sources like our own website. We analyze all files with dozens of anti-virus programs before offering them for download, including XAPK files. But we can’t guarantee that other downloading sources do the same, so we recommend that you only download XAPK files from reliable sources.
