You can store many files into a single one, but the result cannot be used by anything except your program (to put them back to normal) -- the pictures cannot be seen, etc, because the file format is now way different that the standard jpeg format.

To do this, you simply open your current existing file, write the whole thing to a new file, insert some sort of "break" delimiter or start with the number of bytes or something like this to tell where one file stops and another starts. THen open the next file, and write it. Over and over, open a file, read it, write it all into your blob-file. One easy way to do this job is to use the free zip library to zip up all the files (zlib is its name) into a single file, this does all the work for you and the final file saves space too.


Now you mentioned folders in the topic, but not in your question. Did you mean, instead, "how do I copy the related files into a single folder" ?? If this is the case, there are several ways. You can open the existing file, open a file to write to, read the input and write the output, pretty much a done deal. You can also be lazy, and use operating system commands to do this inside your c++ code, the same way you would do it by typing commands in a command window.

Clarify what you really want to do here (the top or bottom option, or something else?) and I can toss some example code at you.

And please, use english this time. Its... annoying ... to read ... something.... like.... this!!!
