# Ubuntu – “Input/output error” when trying to access Windows directory from within Ubuntu

dual-bootnautiluswindows 10

I have Windows 10 and Ubuntu 17.10 installed together as a dual-boot system. When I try to copy files from the Windows 10 system directory I encounter this error:

I am pretty sure that Windows runs normally – I can read the files under Windows 10. And I am also sure that the files are not corrupted, since if I use ls in the terminal, I can get the output as expected:

I can also open any subdirectories of the "Windows" directory using nautilus, by using cd to navigate to that directory first, then using nautilus ..

Only the "Windows" directory can not be opened in nautilus. What can I do to resolve this error?
