hello .
dose any one know how to chang the backup format .bak to .sql
i download the backup of .bak format,but i cant upload as .sql ,i can't chang it .

Open the file; its probably SQL text, just the extension is .bak.

thanks.but use which program to open it ?

this is the pic of the backup .

just change the extension to .sql - and use wordpad or notepad to view it, it's probably just a regular text file

Open Notepad, then click and drag the file to the notepad window.

first thank you for your advice.
but,i tried and failed.
there is the pic in the Attached Images

So, it's a binary file then. Try changing the extension to .zip or .sql.gz and see if Winzip will open it in either case.

it doesn't do also..

MSSQL server backups databases in .bak files. If this is MSSQL backup file, then you will have to use SQL Server Management Studio to import this file to a database.

If you don't have accesss to MSSQL server, then you can download the free express version from http://www.microsoft.com/sql/editions/express/default.mspx

try opening it in notepad or any plain text editor then saving it with the file extension that you want, this only works for ascii files...
