Ext2Fsd is a Windows file system driver for the Ext2, Ext3, and Ext4 file systems. It allows Windows to read Linux file systems natively, providing access to the file system via a drive letter that any program can access. You can have Ext2Fsd launch at every boot or only open it when you need it.
Can Linux read Windows files?
Because of the nature of Linux, when you boot into the Linux half of a dual-boot system, you can access your data (files and folders) on the Windows side, without rebooting into Windows. And you can even edit those Windows files and save them back to the Windows half.
Can Linux read NTFS files?
If you mean a boot partition, neither; Linux cannot boot off NTFS or exFAT. Additionally exFAT is not recommended for most uses because Ubuntu/Linux cannot currently write to exFAT. You don’t need a special partition to “share” files; Linux can read and write NTFS (Windows) just fine.
