This subsection describes various functions compress and decompress files. The data compression and decompression features are
implemented in B4P in the library file 'Zip Library' and makes use of the zip program in the standard installation (Linux, MacOS)
or relies on the installed 7-Zip program on Windows installations because 7-zip provides a set of compression and decompression commands
which Windows does not. See 7-zip for details.
Note: All Microsoft office featuers, e.g. loading Excel files, rely on these file compression and decompression functions.
