Files can be seen in explorer but can not be accessed - help

[Guest]

I have a portable drive to which I would usually back-up my files. I have the
following problems:
1. I would explore to a folder or sub-folder on this drive and can see all
my excel files. but
2. When I click on some of these files, an excel message will be displayed
that the file cannot be found and "if you are launching your files from a
recent document list, be sure that the path and file names are correct"
3. These files had been copied from my C: drive and or from the network
drive, they seem to work fine on those drives, but not when I move them onto
the portable drive.
4. what could be happening here?... please help...

Might be a silly question, but are you sure that what you have copied to the
portable drive is the actual file, and not a shortcut to that file?

Thanks for your reply Gordon, but I am very sure I copied the files and not
the shortcuts... At some point in time, I waould open the file from another
drive and save it into the portable drive, but the same thing will happen...

strange as it may seem, but my colleague told me that it may have something
to do with user access/restrictions set-up from the network... I'm not too
sure about that though... would you happen to know anything about it?

Thanks again
