A.F.9 lets you edit files by replacing characters or any other bytes. The functionality is similar to a replace function in text editors, but there are a few differences. You can edit many files in one operation. You can replace several search phrases at a time. You can use characters, decimal values or hexadecimal values for your search and/or replace argument. You can edit really large files, since A.F.9 doesn't need to load the entire file into system memory.
