Hy.
I have a file with binary data , is possible to access to this data for change it?
I can use a disassembler?

You probably could use a disassembler, but it the output wouldn't mean much if the binary file isn't an executable or if it was for a different OS...

A disassembler won't be of much use to you. What you probably need is a hex editor, such as GHex for Gnome or KHexEdit for KDE.

A disassembler takes a program (and only a program, not other data files) and turns it into a human-readable form of source code known as assembly. Assembly is very difficult to understand unless you have a strong background in computer science, and the assembly generated by a disassembler is particularly difficult even for advanced programmers to understand.

A hex (short for hexadecimal) editor is a program that loads a file and displays each byte of the file as a hexadecimal number (ranging from 0 to F), which is typically much easier to edit than the raw binary, and is easy enough to use that even a novice can modify data files when given instruction on how to do so for the specific task at hand. Note that it is not generally appropriate for program files.
