how to open .SER file

I made a backup of the project, there is a SER file extension

I open via notepad but coding is curve

how to open a file to see what's inside?

You can restore it directly inside SER via right click on project listing->modify project->restore

Or you rename it to *.zip and open it with 7zip, winrar or explorer.

i want to create 100 projects

just pasting texts/links/mail

There was an extra app from our customers that did this. Maybe someone still has it?
