VKB,
John's suggestion should help as it will make sure everyone is out of the database. BUT, most SQL server engines run all the time. The engine runs the database and maintains the objects and files.
You should NEVER just copy and paste the AC folder. This can cause corruption, connection losses, and problems with files. When you use AC's backup, it automatically stops and restarts the service.
You can do what you need to do in one of two ways:
Open AmazingUtilities, the one with the goofy guy on it. You should right click and choose to run as admin unless you already are. Now, DO NOT use any of the three big bars. At the top left, click on advanced. There are six objects of which you want to use one or two. The two selections I refer to are the ones which "detach" your databases (the ones in the AC folder) from the SQL Server engines which are elsewhere on your computer. So, one method would be to choose the one that says "Detach databases -- but do not move them." Then you can grab the entire chart, but personally I would just put a new folder on your desktop and move the six databases: AmazingCharts, Meds and Codes both .mdf and .ldf and put them in the folder. Then copy the Imported Items folder if you have imported items, the Data001 folder if you have any images such as a signature file or a picture/photo and just for fun your .xml file. You can put these files/folders in your program at home and you will be all set.
The other method which is similar, would be to choose "Detach and Move Databases." This will give you a window to browse to where you want to store them. Make sure you choose or make a new folder. That will put the databases plus the .xml plus the Imported Items and Data001 folder in the folder. If you do this, though, you would have to copy (not cut) the databases and other folders back into the main AC folder. Whichever works best for you.
Either way, when you are done, you have to open AmazingUtilities and click on the bottom bar so it will reconnect to the databases.
Think of it like a car. The engine of the car would be the SQL Server and the rear axle the databases. If you wanted to remove the axle, you wouldn't want to do it with the engine running and the car in drive. You would put the car in neutral and turn off the engine.
HTH
