Recent Windows versions have a special service (Volume Shadow Service? Use Google!) for this problems, it allows you to take some kind of snapshot of the filesystem. All modifications after the snapshot do not affect your program, so you can safely copy files from a mounted filesystem. Of course, this service can't guarantee that all open files are in a consistent state.

Regarding your locked Access database: Shut down the service, then backup or make at least a copy of the database file, then restart the service and exclude the original, locked file.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
