Removing "NUL" characters

I was having same problem. The above put me on the right track but was not quite correct in my case. What did work was closely related:

• Open your file in Notepad++
• Type Control-A (select all)
• Type Control-H (replace)
• In 'Find What' type \x00
• In 'Replace With' leave BLANK
• In 'Search Mode' Selected 'Extended'
• Then Click on 'Replace All'

Click Search --> Replace --> Find What: \0 Replace with: "empty" Search mode: Extended --> Replace all

This might help, I used to fi my files like this: http://security102.blogspot.ru/2010/04/findreplace-of-nul-objects-in-notepad.html

Basically you need to replace \x00 characters with regular expressions

Try Find and Replace. type \x00 in Find text box, check the Regular expression option. Leave Replace textbox blank and click on replace all. short cut key for find and replace is ctrl+H.
