Until now 2 coders fails flat to do this project so if You are newbie coder PLEASE don't bid Also don't charge more than $27 for this SIMPLE project I want source C code for both programs in pure C (not C++) so I can compile it with Tiny C Compiler for Windows [login to view URL] because I need really small executable for decoder Also I don't create milestone UNTIL you provide working encoder C source I can compile and test If Your encoder will work I then create milestone and then You will create decoder (As you can see from my past projects I always pays for quality work) Program: ----------------- I want to encode file content in empty file names (size zero bytes) on Windows NTFS HDD to use over 10% unused space to store more files If we create empty files for example on C:\z\ directory we have 254 bytes left in file name to encode file content Of course we can create more empty files in one directory to store larger file (we can split file like RAR or ZIP archiver do) You can use first 5 chars of file to store file number and rest 249 chars to encode file content So beginning of file name will look like this: 00000 00001 00002 ... FFFFF Use HEX notation for file name so we can store more files Of course encoded file content will require 2 bytes for all non printable codes (one constant as marker and second encoded as printable char) So finally I need 2 programs: Encoder which will encode file, split them in many empty files with file name which contain file number (5 chars) and encoded file content (rest 249 chars). Of course encoder must also encode file with extension (if any). I think the best way to do that is to use first file to do that so if (for example) the file name we want to encode is: [login to view URL] the first file will look: [login to view URL] in second (and next) file names we will encode content of the file Encoder need 2 inputs: - directory name and directory location to store empty files with long names (for example: C:\z\) - location of the file to encode (for example: D:\files\file to [login to view URL]) Of course encoder must be able to store all kind of files (exe, zip, mp4, avi and files without any extension too) Decoder need 2 inputs: - directory name and directory location which store empty files with long names (for example: C:\z\) - directory in which we will create source file encoded in many empty files stored in directory above (for example: E:\decoded\) Testing: -------------- When You test encoder and decoder use at least this kind of files: - empty file (size 0 bytes) - one byte file (one with printable ASCII and one with non printable ASCII code) - two byte file - big binary file of any kind (EXE, zip, mp4, ...) - size about 20 MB

I may be still a student, but i understand the logic behind the program with my knowledge i am most probably able to do it. I will start working on the project at Saturday. If you don't want to trust me you can just leave a chat open and i will answer to you when i have it ready(also tested). I have worked on binary files with java, so i am familiar with the concept. The price is negotiable. with regards PanosSoF, I am looking forward to work with you. P.S. 1: You can see that i don't bid on projects i can't do or think i can't, the only (not really)problem on this one is my experience on C API's (something i can find easy on the internet). P.S. 2: If you are not interested in my offer just don't open chat(This way i won't start the project), else if something changes in the meantime please notify me, because i have a busy schedule.
