I frequently work with access files,but yesterday I was astonished. Because my files were lost irrelatively unexpectedly. To my good fortune I entered a friend's house and saw there an interesting tool on his PC. I used the Google and found it on a soft blog - Repair MDB file. I wondered when it resolved all my problem for a minute and absolutely free it I didn't make a mistake. I recommended it for my friends and they told me: Thanks. And gave me a bottle of wine))
