I have an ubuntu and windows on dualboot. While I'm mainly using ubuntu, I would save all my work in the windows directory, which is an ntfs. The partition is mounted as follows:UUID=ACAEAD7DAEAD4126 /media/windows/ ntfs rw,auto,user,exec,nls=utf8,umask=003,gid=46,uid=1000    0   0I have a pdf file that was originally obtained while on Windows which I cannot read in ubuntu (read will return EACCES (Permission denied)). It opens fine in windows.$ cat lab2.pdf cat: lab2.pdf: Permission denied$ sudo cat lab2.pdf[sudo] password for randy: cat: lab2.pdf: Permission denied$ ls -l lab2.pdf-rwxrwxr-- 1 randy plugdev 57096 Jan 11  2016 lab2.pdfI've also tried to remount the partition to give full permission:$ sudo mount -t ntfs-3g -o gid=randy,uid=randy /dev/sda5 /media/windows/$ ls -l lab2.pdf -rwxrwxrwx 1 randy randy 57096 Jan 11  2016 lab2.pdf$ cat lab2.pdf cat: lab2.pdf: Permission deniedThe weird thing is that I haven't found any other files in the windows directory having the same issue. Would appreciate some help, thanks!
