There are several reasons to add a database:

• The database was removed from the Database List Manager
• The system database became corrupted and needed to be swapped with the blank saved copy
• The database file was copied from another system (an unsupported migration) 

The preferred method of moving data is by the Restore Company function. See How to migrate Sage Fixed Assets Single User products. If you can’t access an existing installation of Sage Fixed Assets and have copies of the database files, follow the process below:

1. Create a new folder in the default data folder.
2. Copy the best.db, fas.db, or *.bdb files to the new folder on the system where you installed the single user product. Don't move any .log or .id files.
3. Go to File, Database List Manager.
4. Click Find, Browse to where the databases are located, click OK, click Search.
5. Once found, highlight the database, click Add.
   • If the database is already named in the Find screen and it’s already Database List Manager, you don't need to add it again.
   • If the database is not-named, there will be a prompt to give it a name. Both the Database Name: and the Database File Name: will be available. Don't change the Database File Name:, but enter a Database Name:
6. The database will disappear from the list of found databases.
7. Click Close, and Close.
8. Go to File, Open Company, select the newly added database, select a company from the list, click OK.
