backup database

[cnicolapc]

Hi,

I'm trying to backup a database (Example: data.db) by making a copy (eg: data.bak). But when I copy the backup file to restore your data restored. I've seen in dirRootExternal that files are created with different extensions data.db, data.db-shm, wal-date. What could be the problem?
thank you very much
Backup:

File.Copy(File.DirRootExternal,"Libri.db", File.DirRootExternal,"libri.bak")

Restore:

File.Copy(File.DirRootExternal,"Libri.bak", File.DirRootExternal,"libri.db")

Be careful, in the two code lines you are mixing up lower case and upper case characters.
With correct names it works, tested for another user.

Best regards.

These two files are the database journal files.
