- Google will make EROFS the default read-only file system in Android 13.
- The file system was initially developed by Huawei.
- Solely units that launch with Android 13 and Google’s companies will make the change.
Google is making an attention-grabbing — and doubtlessly controversial — choice with Android 13, deploying a file system developed by Huawei.
Based on Esper, Google is planning on together with the Enhanced Learn-Solely File System (EROFS) in Android 13, making it the default read-only system. The file system was created by Xiang Gao when he was working as an engineer at Huawei. EROFS provides important advantages over current file techniques, together with space-saving compression and pace. This might result in a lot sooner updates and fewer cupboard space getting used.
Huawei developed EROFS for inclusion within the Linux kernel, which types the idea of Android. Regardless of finally being locked out of the Android ecosystem by US-led sanctions, the file system formally turned a part of the Linux kernel, starting with Linux 5.4. It has additionally been used on tens of millions of Huawei units and is being adopted by different producers.

Google now plans to make it the default file system for read-only partitions, comparable to these utilized by the core Android system. Because the system partition is often read-only, compressing it’s an interesting choice to avoid wasting house on recordsdata that solely change when a system replace is carried out. Sadly, most compression techniques have important efficiency hits, a limitation that EROFS particularly addresses.
Google throwing its weight behind EROFS doesn’t imply that every one units will mechanically use it. The change will solely influence units that launch with Android 13 by default and solely those who have Google’s companies in-built. Meaning units working AOSP (Android Open Supply Undertaking) won’t use EROFS.
