I need help to write the sql script to find the latest backup file from the windows folder to restore the database. filename is like:- 

dbnm_2019_4_5_11_30_613.bak
dbnm_2019_4_18_11_32_234.bak
dbnm_2019_4_11_11_37_34.bak

... name is made up using dbnm_year_month_date_hr_min_sec format.

used below script:-

CREATE TABLE #File
     ( FileName    SYSNAME,
        Depth       TINYINT,
        IsFile      TINYINT
        );
 INSERT INTO #File
        (FileName, Depth, IsFile)
 EXEC xp_DirTree '[file location]',1,1;

is there anyway that I can insert date filed from the network folder to show when the backup file created and do the order by on that field to find the latest file.

when I am using top 1 in select statement, it is showing me 2019_4_5_11_30_613.bak as latest file which is incorrect.

SQL Server recovery databases from files only from computer unitys (c: d: ).

To get the backup sets I use this statment:

SELECT
    database_name as DataBaseName,
    physical_device_name as PhysicalDeviceName,
    backup_start_date as BackupStartDate,
    backup_finish_date as BackupFinishDate,
    cast(backup_size/1024.0 as decimal(19,2)) AS BackupSizeKB,
    cast(backup_size/1024.0/1024.0 as decimal(19,2)) AS BackupSizeMB,
    cast(backup_size/1024.0/1024/1024.0 as decimal(19,2))  AS BackupSizeGB
FROM msdb.dbo.backupset b
JOIN msdb.dbo.backupmediafamily m ON b.media_set_id = m.media_set_id
where cast(b.backup_finish_date as date)= (cast(getdate() -1 as date))

ORDER BY backup_finish_date

Pay attention to the clauses: WHERE and ORDER BY.

There is another way to get from windows folders the last file using powershell. Take a look into Keith Hill answer here: Finding modified date of a file/folder
