I am moving databases from one instance to another (by detaching databases from the first instance, move MDF
and log files to another location, and attach them to the new instance), unfortunately could not attach some of them, and miss calculate number of databases that have issues, how to check all MDF
files that is not attached to SQL server from specific directory.

Best Answer
You should use powershell for automation and backup restore for a guranteed way of migrating your databases.
For powershell, use dbatools -->
COPY-SQLDATABASE
or for migrating entire server with logins, jobs etc useStart-SqlMigration
Why not backup restore ? detaching and attaching database files for moving from one server to another is not a recommended approach !
You can use
Find-DbaOrphanedFile
to find out orphaned database files.mdf, .ldf and .ndf files
