I've read the previous post on this issue, and the replies were informative but I still don't know how to get rid of an access.lockfile.9 file that appeared in my folder last week. I created the database that it refers to a few weeks ago, and have not had problems until now. The database is on a shared drive, accessable by about 20 people in the office. I created and modify the database on my local (C drive, make backups every evening on my C: drive, then transfer the modified version to the shared drive for use by the office. When I tried to do that this morning, the system would not let me delete the old .mdb file to replace with the modified version. That's when I noticed the .ldb file labeled access.lockfile.9 How do I get rid of this file? I can't delete, rename or move it. No one else has the database open.
