Ext2Fsd is a free open-source driver for Microsoft Windows that allows the system to work with Ext2, Ext3 and Ext4 file systems. To work with it, start the Ext2 Volume Manager, select the disk or partition in Ext2, Ext3 or Ext4 format that you want to mount and assign it a letter. The last release dates from 2017.
The main benefit of using Ext2Fsd is its ability to enable Microsoft Windows systems to read and write to Ext2 and Ext3 file systems.
