Opening issue

JUMP TO SOLUTION

Hello everyone!
I am new to this website and am seeking some advice.. (also forgive me if this isn't in the right spot, let me know and i'll move it right away)

I just recently started using Windows 10 on my Samsung laptop. But after upgrading Windows i cannot open .mdf file. I never had this problem with my last OS.

Any suggestions ideas would be great.

MDF is the extension used by SQL Server for SQL databases.

You’d need to install some version of SQL Server, then re-attach the MDF file. However, if you don’t have the matching LDF file (the log file), you don’t have the whole database.

Because of this, an MDF file is not the correct way to transfer databases between servers. Instead, you need to make a backup using SQL Server Manager, then restore the backup on the other server.

If you need a free version of SQL Server, you can use SQL Server Express.

Went ahead and moved it over to our computers section for you. Smiley Happy As far as the issue goes, can you tell me what the model code of your laptop is and what the previous version you upgraded from was? (Like 7 or 8.1?)
