ext3
open-in-new
<p>ext3, or third extended filesystem, is a <a href="/facts/Journaling_file_system/UCAaSBrD">journaled file system</a> that is commonly used with the <a href="/facts/Linux_kernel/dlkduHuA">Linux kernel</a>. It used to be the default <a href="/facts/File_system/FdPm90uc">file system</a> for many popular <a href="/facts/Linux_distributions/0vVl4N4f">Linux distributions</a> but generally has been supplanted by its successor version <a href="/facts/Ext4/zFbQRpsh">ext4</a>. The main advantage of ext3 over its predecessor, <a href="/facts/Ext2/ftyVw4Kv">ext2</a>, is <a href="/facts/Journaling_file_system/UCAaSBrD">journaling</a>, which improves reliability and eliminates the need to check the file system after an improper, a.k.a. unclean, shutdown. </p>
