Cannot view files I own

[donald]

I’m not sure if it has anything to do with updating recently but all the files and folders in a directory (/mnt/VirtualDrives/downloads/) seem to be hidden even though I am the owner and permissions seem ok!
for example-

$ sudo stat /mnt/VirtualDrives/downloads/ThinkingInPython.zip 
  File: /mnt/VirtualDrives/downloads/ThinkingInPython.zip
  Size: 544830          Blocks: 1080       IO Block: 4096   regular file
Device: 8,66    Inode: 2588728     Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 1001/  donald)   Gid: (  100/   users)

$ ls -al /mnt/VirtualDrives/downloads/ThinkingInPython.zip 
"/mnt/VirtualDrives/downloads/ThinkingInPython.zip": Permission denied (os error 13)

Also trying to view the folder in konqueror or dolphin shows the folder as containing 286 items but trying to enter it shows it as empty.
The files seem ok as I can copy to my home folder using sudo.

Does anyone have any idea what the problem might be?

[Tutorial] Understanding and working with UNIX filesystems and permissions

Difficulty: ★★★☆☆ Note: This post is meant as a tutorial. Please do not post on this thread regarding any problems you’re having with permissions, but start a new thread instead. Thank you. PREAMBLE: THE HISTORICAL BACKGROUND If you are new to the world of GNU/Linux ─ and especially if you come from the Microsoft Windows ecosystem ─ then you will undoubtedly have already noticed that GNU/Linux handles permissions and storage volumes quite differently from what you might be used to …

[Tutorial] Working with additional 'drives'

Difficulty: ★★☆☆☆ 1. INTRODUCTION Microsoft Windows started its life as a graphical user interface on top of MS-DOS, a 16-bit single-user, single-tasking operating system that in turn originated as 86DOS, an unauthorized 16-bit rewrite (by Tim Paterson of Seattle Computer) of Digital Research’s originally 8-bit CP/M operating system. Both CP/M and MS-DOS were at the time developed for computers that did not support any other storage media than floppy disks. Considering this legacy, Microsof…

How many users are on that machine? Mind you, but User has to be part of at least:
uid=1000(user) gid=1000(user) groups=1000(user)
and Otheruser
uid=1001(otheruser) gid=1001(otheruser) groups=1001(otheruser)
Then the other groups follow, depending for what you need them. For example:
3(sys),90(network),98(power),108(vboxusers),991(lp),998(wheel)
and 1000(autologin) if you use autologin …

Anyway, follow the links above.

I found that the execute permission was missing on the directory.
