* 2) is this file already existing ? yes-> 3)
* 3) this file does not exist -> 4)
*
* 3) file with this name and ID exists is already, cancel reception, show file
*
* 4) file dows not exist, receive the blocks
* 5) a block is missing -> find a previous block-file with this name+ID. If exists, take the block from this file
* 6) reception complete, the files is OK -> save the file, delete a block file
* 7) reception complete, the files is incomplete -> save the block file for late use
*
* Filenames:
* ----------
* transmitter:
* the sender takes any filename, but the ID is the C&C16 over the file contents (to identify different files with the same name)
*
* receiver:
* use the filename as transmitted for the good original file
* the blockfile's filename is the ID in Ascii-Hex representation, i.e.: ID= 0x45 0xfe ... filename is: 45FE.blk
