I weep as I write this I created a document worked on it and saved it [Mac Office 20004 Word]. When searching for keywords in the document a few days later having forgotten its title, I was surprised to receive no returns despite some distinctive keywords. To cut a long story short I could only find this file by going to Project Gallery in Word and selecting 'within the last month' whereupon I found the file. After closing it down [mightily relieved as it is an important document] I found today that the file is no longer appearing in Project Gallery and although it is listed in File/Recent Files the link generates a message that the file cannot be found. I have been backing up with Time Machine to a 120 GB Maxtor drive and it isn't there either. If I filter by date last opened it doesn't find the file but does find another file that I had open at the same date and time. I didn't delete the file. Why might it have disappeared twice? Does anyone have any suggestions? I have tried searching Time Machine with finder and also used Terminal to make hidden files visible.
