Windows doesn't start files on double click

I have recently carried out clean install of OS. on C:\

My documents, videos, pictures etc are on E:\
Locations are set correctly as per:http://www.zdnet.com/blog/bott/windo...o-size_p2/2941



While I can see them to browse, and can copy move etc. .... if I double click on an item to open I get error:

"Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access them."

For example I double click a video file I get that error ... yet if I carry out via right click :
open with> VLC media player

It opens and runs fine.

I followed the procedure in the url in the 3rd line of post ...
i.e left user profile on C:\ but changed location of Mydocs, My pics folders etc.

I'll offer my $0.02 as I've done reinstalls where I've maintained files on a 2nd drive separate from the boot device. In my case, the ownership of the files is what it was from the prior installation even though I'm the same use. To fix it I change the ownership and permissions on the files on the previously existing partition to the new userid and all is well.

In my case I would mirror the structure and place a "users" folder on the D: drive with the user name as a subfolder (i.e. D:\users\<username>). After changing the owner/permissions the username folder would then have the lock icon on it so I knew it was correct.

Again, this is if the files already existed on a separate partition from a prior installation as opposed to moving them after they already existed on a C partition.
