Sharing files between two machines

I have two machines, both running Ubuntu 12.04 - one my main machine and the other an old Thinkpad - and both running LibreOffice Writer. Before I got hold of the Thinkpad, I began writing a document on my main machine with no problems. When I got the Thinkpad, I copied the document onto a flash drive so that I could work on it away from home, copying the edited document back onto the flash drive and then, after returning home, copying it back onto my main machine.

But now I find that I can’t open the document on my main machine unless the flash drive is inserted, even though it’s right there in my document folder. Effectively, that means that I do not have a valid copy on my main machine any longer - a situation which worries me slightly.

It seems that I’ve unintentionally created a link which I didn’t want.

Any ideas from anyone, please?

This sounds like a permissions issue, I would look into the Ubuntu forums, otherwise the file itself that is in ~/Documents could be corrupted or simply a shortcut to the flash drive

You’re absolutely right - it IS a Permissions problem. I still haven’t solved it, but at least I know where to look now. Thanks.

@Poodle - Please allow me a small question. Which Thinkpad models are you using to run Unbutu?
I have an old Thinkpad and consider since a while to replace Windows with Unbutu, therefore your information could be very helpful for me. Thanks in advance for your kind answer.

It’s an A30 with 512MB memory. I actually used Xubuntu 12.04 on the Thinkpad, which is slightly smaller than the full blown Ubuntu installation, and had no problems at all during the process

@Poodle - Thanks for this information!!!

@Poodle,

If you open the file, is it possible to re-save the file to a new location on disk, and then access the file from that new location without the flash drive inserted?
