Paragon ExtFS can't write files to Ext4 drive from Windows 10


Windows 10 Home version 1607 64-bit

Product link:

I seem to be able to read files but I can't write files. I get the error:

An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem.

Error 0x80070057: The parameter is incorrect.

None of the "Read-only" checkboxes are checked, they're all cleared.

Also, Explorer (my taskbar and such) crashes sometimes when I try to write a file.

I solved it as follows: I uninstalled all 3rd party software like Ext2Fsd, ext2explore, etc.

I cleaned the registry, restarted and paragon extfs is now working. It's copying files to Linux HDD at 100mb/s.
