问题
I've searched in StackOverFlow website and over the internet for this question and its relevant questions but I still haven't got a clear answer. I want to know what software may I use to convert any file (regarding size) into a text file that contains zeros and ones (only) of this specific file, then convert this text file that contains these zeros and ones back to the original file. Execuse my ignorance if the files that contains zeros and ones are not called "binary files", I searched the internet and read in wikipedia there are software called [hex dump], I don't need those, I need what I mentioned above, thank you all.

The thing is, that all the files are already are binary, you just need any HEX viewer to see them properly, as they are. For instance, you can use "Compare by content" from Total Commander).
There is no-"no binary" files in the computer world.
HEX means base 16 system, you can easily convert it to 2 based (1,0), by using simple windows calculator in Programmer mode:
In the picture below, a text file has been compared by itself, using Binary switch, just to show it's content in HEX way, and first digit is "66", we place it into calculator when HEX mode is activated and then switch to BIN, and have 1100110 - this for letter "f" and so on.
P.S.#1. Interesting thing is that there is no real emphasis on this matter in Wikipedia nor other sites, I think this is totally confusing for people who don't know this already, I think they should have the word binary in the first line of definition of the computer file.
A computer file in its deepest level is binary data, not a piece of information in lines and some different (from binary) formats. The file format is only a protocol to store bytes and information it becomes only when it has been read or opened by someone or something in understandable way, meaning that the user, or client software knows how that data (bytes) has been written in this particular file.
P.S.#2. WTF? - Wikipedia has split files to binary and non-binary! Thank God I don't need to read this.
Software to create text representatives from binary input and vice versa: Windows, Online
回答2:
This method works with bash terminal
Convert your file to hexadecimal
$ xxd originalFile > hexaFileConvert back your hexadecimal file to original
$ cat hexaFile | xxd –r > backOriginalFile
