The backslash character is used as an "escape character", it is used to insert a special character in the string. To insert a tab stop for example, you would use "\t". If you wnat to have a literal \, you have to escape it with another \. So your string should be "C:\\Users\\ABHIJI~1.SHE\\AppData\\Local\\Temp\\myoutput.txt".

Example:

# right
>> puts "C:\\Users\\ABHIJI~1.SHE\\AppData\\Local\\Temp\\myoutput.txt"
C:\Users\ABHIJI~1.SHE\AppData\Local\Temp\myoutput.txt
=> nil

# wrong
>> puts "C:\Users\ABHIJI~1.SHE\AppData\Local\Temp\myoutput.txt"
C:UsersABHIJI~1.SHEAppDataLocalTempmyoutput.txt
=> nil

However, you can also use forward slashes in paths, even on Windows. For more details, see this answer https://stackoverflow.com/a/14875567/1067124.

f = File.new("C://Users//ABHIJI~1.SHE//AppData//Local//Temp//myoutput.txt","w+") Not working Even forward slashes also not working – Abhijit Apr 26 '14 at 12:29

@Abhijit When using forward slashes, use only one. You only have to double them when using backslashes. `"C:/Users/ABHIJI~1.SHE"` is equivalent to `"C:\\Users\\ABHIJI~1.SHE"`. – Holger Just Apr 26 '14 at 12:30
can you run `dir C:\Users\ABHIJI~1.SHE\AppData\Local\Temp\` in a command line prompt to see if the folder exists? – Benedikt Köppel Apr 26 '14 at 14:15
