Title Body

I made a tool in Delphi to create a rainbow table. It was fine until the file grew up to 3.1 GB. I closed my program. Then I opened it again and it crashes while executing this code: Assign(RainbowFile,'Rainbow_table.txt'); {assign a text file} Append(RainbowFile); Delphi shows the error raised exception class EInOutError with message 'I/O error 131'. My question: how do to append data to an existing file larger than 2 GB. [Obsolete] Next question: Currently I have in my code: Content_to_file := (#13+#10+Start_string+':'+ hexstr(GTA_San_Andreas_CRC32(Start_string), 8)); RainbowFile_handle.WriteBuffer( Content_to_file[1], Length(Content_to_file)*SizeOf(Char)); How do you get rid of the Content_to_file variable? I want put it directly to the WriteBuffer if it’s possible. 1 st edit TFileStream works with files bigger than 2 GB. I tested it now. However is it possible to write like so: RainbowFile_handle.WriteBuffer( Start_string[1]+':', I mean to pass no variable argument. Or do I definitely have to pass the first char of a variable? 2 nd edit I have currently made it work this way: Content_to_file := (#13+#10+Start_string+':'+ hexstr(GTA_San_Andreas_CRC32(Start_string), 8)); RainbowFile_handle.WriteBuffer( Content_to_file[1], Length(Content_to_file)*SizeOf(Char)); Is it possible to do it without this variable?
