Linux Reader is an application that lets you explore Ext2, Ext3, and Ext4 Linux file systems not recognized natively by Windows operating systems. It is common for people who work with both Linux and Windows on the same PC that at some point after making a Windows reinstallation, the boot loader gets overwritten so you can't access your Linux operating system anymore. This is when this utility comes in handy, because you can use it to access those files you thought were lost.
This program has a GUI that resembles the Windows Explorer, so navigating through the files and folders will be an easy task. It displays thumbnails for images, videos, or PDF files, as long as you have their respective programs to open them with. Once you have located the files you're looking for, a double-click opens an Export Wizard, which lets you retrieve files to your Windows partition or disk.
For security reasons, the only task you are allowed to do is saving files and folders. You don't have writing permission so you can never mess with the sensitive data that could potentially damage your Linux system. The possible downside is that you actually can access files from users with password-protected accounts.
Other supported file systems are ReiserFS, Mac HFS and HFS+, and Windows Fat, exFAT, and NTFS.
