Using MS Access 2010. I have a field in a table that contains windows path names surrounded by quotes, like this
\"C:\\My Documents\\Photos\\img1.jpg\"
\"C:\
To make this a permanent change, you might run an update query that looked something like this:
UPDATE [Your Table]
SET [Your Table].[Your Field] = Replace([Your Table].[Your Field],"""","")
This will get rid of all quotes, even if they aren't at the beginning or end. Post back if that's not exactly what you want.
