FSTAB File Extension

Have a problem opening a .FSTAB file? We collect information about file formats and can explain what FSTAB files are. Additionally we recommend software suitable for opening or converting such files.

What is the .FSTAB file type?

An abbreviation of 'File System Table,' the ".fstab" character string is a dotted portion of a filename, rather than an extension. It belongs to the "/etc/vold.fstab" configuration file, with reference to the Android operating system (Google, Inc.) for touch-screen mobile devices. On GNU/Linux and other Unix-style OS'es, the same function is performed by the "/etc/fstab" configuration file.

One of system configuration files on Android, vold.fstab defines how and in what order filesystems are mounted during the system's boot. It is a regular text file that can be edited with a text editor. Editing the vold.fstab file requires the superuser rights (root) and involves a high risk of rendering the system unstable or non-functional. It is always a good practice to create a backup of the vold.fstab file before any changes are made.

The vold.fstab file is often used for tweaking on-boot filesystem mounts as well as 'hacking' storage devices. For instance, vold.fstab can be used for swapping a small internal storage with a larger SD-card volume as a rather messy workaround for some memory-limited Android devices.
