For some reason I can't open files on drive
First thing, make sure that it's no locked and that you have the correct permissions :


If you have extended attributes you can get rid of those by doing the following :

1- Do ls -l@, under the file it will give you something like "com.apple.FinderInfo". Copy that
2- Do xattr -d com.apple.FinderInfo path/to/file

If nothing works then your last option is to sudo it :
sudo open path/to/file

Also see if you can open it using a mac that those not have Tuxera installed on it.
