Also, you're reading the file byte by byte, why don't you read in all bytes at once an then convert the byte array to a string using the Encoding class

i cannot read in my format, its a file format of a game, thats why i have to read like that

Use a StringBuilder instead and replace += with its Append method.

filename += br.ReadChar();

filename.Remove(filename.Length - 3);

That doesn't accomplish anything. The Remove method returns the new string, so you have to take care of the return value, just as you do with the Replace and Trim methods.

Use the ReadChars method to read several characters from the stream

i just want to remove this from last of string, not in all

filename = filename.Remove(something...);

but if i use replace then it replace all the "//" from string , i just want to remove this from last of string, not in all

yeah i used that but its just return "System.Char[]" something like that
