file encapsulation / compression, Flwrap is an software that is designed to take care of each of these situations. Flwrap allows you to transmit a text message, image, or binary file to either single or multiple stations and allow each receiving station to verify that the transmission was received without error. In the discussion which follows the software name is Flwrap, the file encapsulation process is called wrap, wrapping and the encapsulated file is said to be wrapped.

A text file is encapsulated without changes to the text. Images and other binary files are first converted to a base-64 format. The converted file is then encapsulated. The header blocks identify the type of file and whether or not it has been converted to base-64. Files with any of the following extensions will be treated as binary data files and converted to the base-64 format: jpg, jpeg, png, gif, bmp, ico, zip, gz, tgz, and bz2

Using flwrap is very simple. Install the executable file and then create a short cut to the executable on the desktop.

flwrap also compresses and expands files in addition to encapsulating them. Binary files such as a MS Word file or an executable must be converted to base 64 before being wrapped. Those files are first compressed before the base64 encoding is applied. A Word document recipe for Pfefferseuse cookies is 11 kB. When wrapped by flwrap it is 3.1 kB in size.

The wrapped file is an ASCII text file suitable for transmission using any of the fldigi modes other than CW, RTTY or the fuzzy modes such as FeldHell.
