mdf is the extension of primary file.
ldf is the extension of transaction log file.
whenever u create a database, u have to name the above fiels.
Generally their location path is c:\programfiles\microsoft sql server\mssql\logs

.mdf is the default extension name of datafile.
.ldf is the default extension name of log file.

Ok, thanks I also needed to know what those files are, but what can I do if I only have them, I mean I have a file called asdb.mdf and another called asdb_log.ldf; how can I get the DB from them?

.MDF and .LDF are usually associated with SQL. In order to view the data you will need SQL Server. The .MDF file is the primary file.

Yes, I know that, I have SQL Server 2005, but how can I upload these files?

You need to attach the database to the default instance. (SQL Server) Once attached, you can view the tables or data in that .mdf file.
