Hi subhash,

Get logical file names as follows

restore filelistonly from disk='your backup path\filename.bak'

then restore database as follows,

restore database database_name from disk='your backup path\filename.bak'

with

move 'Logical_name for mdf file' to 'Path where you want to create .mdf file',

move 'Logical_name for ndf file' to 'Path where you want to create .ndf file',

move 'Logical_name for ldf file' to 'Path where you want to create .ldf file',

stats=1

Note:- Depends on number of your .ndf file use move to part.
