how can I open a file with .nsf extension on my window?

NSF files are a product of Lotus Notes software. The corporation I work for used to use it for email and custom in-house applications before they moved to Microsoft Exchange. \n\nIf you don't have a copy of Lotus Notes you may be able to read it by changing the extension to .TXT and opening in Notepad. However, you're very likely to see a mess of jumbled text and characters. \n\nI think the NSF file is kind of the equivalent to how INI files are used by other applications. I believe info like how you have your Notes desktop arranged, your email configured, etc. are all contained in there so it'll be a real challenge to read w/out having the Notes client. I don't know if saved email is contained in there or not, and again I don't know if it'll be at all readable. Good luck!

you probably don't have the correct program to view the file. Check the Microsoft website to see what you need to open it.

It is called "extention".\n\nSo, you need an extension list.\nOne of them (very wide) is attached. You can obtain there an alphabetically list of extensions as well as associated extentions with some program.

Try this link.  It leads to a program that lets you open a .dwf file.\nhttp://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=2404513

I would need to know what kind of file it is. Usually if your computer can't open it, it is because it is either an incompatible file, or  the program that created the file isn't on your computer.

The file button the first button on the second line from top in any window... just below the title bar.\n\nIf you cant find it then try the keyboard shortcut Alt+F. The file menu will automatically open.

In windows, right click the file and go to properties.Alternatively select the file and press Alt+Enter.then at the bottom of that window  uncheck the 'Read Only' check-box.\n\nHowever note that the question is not clear.You said 'program' and I had to interpret it as a 'file' because there is no way that you can alter a program without having its source code or by using some what advanced tools like hex-editors,disassemblers,etc.However if you have the source code, you can open it with a suitable program and recompile it with the suitable compiler.You need to recognize the language in which it is written.

Try opening the file in "append" mode instead of "write" mode, like:\n\nfp = fopen("MyFile.txt","a");  /* use "a" instead of "w" */
