I found this code which restores all backupfiles from a directory to a single server. Does not work due to folder not found issues. How can I restore all databases :- all mdfs to a single folder and all ldfs to a different single folder using the above code.

I need to capture the initial logical names using FILELISTONLY and then use MOVE to move the mdfs to one folder and ldfs to another respectively.

Thanks

Just use powershell DBATools ( free modules ) DBARestore

$File = Get-ChildItem c:\backups, \\server1\backups
$File | Restore-DbaDatabase -SqlInstance Server1\Instance -UseDestinationDefaultDirectories

Just keep in mind the target server service account needs access to the backup files

SET @LogicalNameData=(SELECT LogicalName FROM @Table WHERE Type='D') <---- If more than 1 mdf file it fails to work as it results more than 1 value.

.How can I get this to work for multiple files...mdfs/ndfs files...

SET @LogicalNameLog=(SELECT LogicalName FROM @Table WHERE Type='L')

Did you install-module dbatools ?
