how to remove blank spaces in html file name

You can use Move method like:

 

System.IO.File.Move("oldfilename", "newfilename"); 

 

Steps can be:

1) Create a dictionary where key is old file names (with spaces) and value would be new file names (without spaces) 

2) Initially your dictionary will hold only keys

3) Next is to populate value filed in dictionary. That you can do it from fetching each key and remove spaces(this you can get it on google - how to remove spaces from string) 

4) Now you have both key and value ready with you.

5) Final step is to call the Move function as I have shown above by iterating all teh key/value pairs of your dictionary.

 

Hope it makes sense.
