Perhaps a bit off subject. I'm not sure. But I figure there are folk here using ext4 file systems, so... I have a new requirement to be able to read/write ext4 file systems from Windows. It's like this: we have a data collection system that collects data to a mix of ext4 and vfat disks. For whatever reasons. We have usually accessed all of these from a Linux system where file system support is really great. Unfortunately, the powers that be have decided to set up a system that is Windows-only. Sigh. I have tried installing openSUSE Leap 15.6 in WSL 2. It actually works great. My motivation was that I should be able to mount the ext4 partition via wsl, and then access it in Windows. See, for example, https://windowsreport.com/ext4-windows-11/. That is sort of true if by 'access' you mean in Windows Explorer only. That is not a workable solution. I need access in programs and shell scripts. I then tried a product like Linux Reader. It is geared towards file recovery. Why anyone would use a Windows computer to try to recover files on an ext4 system is a real mystery. It also seemed to caution that it really wanted to be a read-only thing. Not a confidence booster. And not what I need. Finally, I tried Paragon Software's ext4 for Windows. It seems to be properly read/write and, generally looks great. But then I see that I cannot access SQLite databases that are on these disks. SQLite (general programs and database browsers) all complain that the database is locked. We had this issue when, from Linux, accessing databases on CIFS mounted drivers. That was sorted by adding nobrl to the CIFS mount command on Linux. It's a known issue. So this method was close, but no cigar. A support question is pending as I cannot think I am the first person who wanted to access an SQLite database this way. So my question here is if anyone has any experience with Windows software that lets one mount ext4 file systems read/write. It has to work from programs and shell scripts, not just in a file system browser GUI. -- Roger Oberholtzer
