New releases of NX1 will be in 3 standard downloads.
1 - PROGRAMS - ALL PDA CABS and the windows desktop installer.
2 - DATA-FOLDER - Either VGA or QVGA
3 - Optional Add-ins - 'Birdsongs' folder if you want to hear bird songs
In future releases you will only need to download the PROGRAMS.
If new releases have extra or amended data there will be a DATA-FOLDER UPDATE download to upgrade your data set. Optional add-ins can be downloaded and used at any time.
You don't need to download the Data-Folder if you already have downloaded it for v5.0!
You can delete all MP3 files from the /NatureExplorer/BIRDS/ folder and this will save 16mb.
If you only have an earlier version's data folder (NATUREDATA or NATUREDATA1) I advise downloading the latest data folder.
I intend to keep this download format in the future, so people will not have to keep downloading everything, with every new release.
This release also has changes to the code to avoid the hang-ups and errors that previous versions caused. I have stopped using MP3 birdsong files as the FMOD library caused errors with 20percent of users' PDAs. I now use WAV files of much better quality and use the inbuilt WAV player to play them so keeping errors within-house. This makes the bird song fileset larger and this is why I have made it an OPTIONAL add-in (a 41mb download). So that those who are not so interested in the Birds topic do not have to download them. For those of us who are interested in hearing birdsongs, the quality of the sounds have been improved from the gritty sounding MP3 files.

Also I have removed some instances of errors in which the program could not 'see' the data folder because of changes in Windows Mobile system since v6.1.
Thanks go out to Pucci463 and Ponrepo for all their hard work on v5, and to everyone who has helped make this program so good.
