Force Dowload in Browser Issue

[random1]

I am troubleshooting an issue with following code for an issue with the download file name.

 

It tries to save the file as '.database_full_backup-2009-06-05-1244173623.sql.'

 

I'm giving it the file: database_full_backup-2009-06-05-1244173623.sql

 

It does donwload the correct data and is the correct size too but the filename is mangled.

Where are the beginning '. and ending .' coming from?

 

Really frustrating! Please lay down some knowledge.
