I recently installed Ubuntu as a dual boot on my Windows 7 laptop. Since I am new to Linux I spend a lot of time just trying to find my way around. One thing has totally surprised me though.

I had a document started in Word using in Win7 which I was able to find and open in LibreOffice/Ubuntu. I made a substantial number of changes to the file and saved it, however, when I reopened Word/Win7 I found that none of the changes I'd saved in LibreOffice were there, and the document looked the same way it had when I'd edited it in Word.

Going back to Ubuntu and trying to reopen in LibreOffice, got a window saying the document wasn't there. Browsing to the directory I was able to open the document, however, just as in Word/Win7, all the changes I'd made during my LibreOffice/Ubuntu session were gone.

Presumably this file is still present somewhere, but where? I don't like having to redo all the editing I'd done. But it's beginning to look like I'll have to.

My first impulse is to say it sounds like some sort of permissions problem.

Where was the file stored in relation to the Ubuntu installation--on a Windows partition or elsewhere?

Did the file appear in LO's "File-->Recent Documents" list?

What is the output when you run ls -l on the file in a terminal or, alternatively, when you right click on the file name in a file manager and view the properties?

The file was stored in its original place, one of my Windows partitions. I opened it from there in LO and clicked "Save" after making changes.

Yes, the file appeared in "Recent Documents", but clicking on that, LO replied, "Document does not exist" (or something very similar).

Browsing to the file's original locaction, I was able to open it, but without all the changes I'd made in LO, as mentioned earlier.

As far as using the terminal, which I'm new at, I tried using various commands like "find" and "locate" and "dir" per Google searches (both using Linux terminal and Windows command prompt) and turned up nothing other than the original file without changes. I also downloaded a program to view the Linux partition from within Windows but never found it.

Try copying the file to your Linux partition, then making and saving some test edits from there.

If the file saves and can be reopened, that will tell us that the issue is directly connected to trying to read from and save to the Windows partition.

The first part of troubleshooting is to identify the cause of the problem with certainty.

Files saved in the LInux partition are completely normal. They reflect the most recent changes I've made to the documents.

I'm going back to my original theory about permissions.

Try checking them as I outlined in my first post. If you aren't sure about how to use the ls command, use the file manager workaround I described. Please describe the permissions in detail or post a screenshot of the permissions tab in the properties dialog.
