Many improvements in performance and stability of the program (large parts of code rewritten):
bug fixed by which some files with names containing "strange" characters (like {}"|()!@#$%^& etc.) would not be processed by the program;
bug fixed in which the rename routine (after a split process) crashed (leaving the resulting split files with unusable filenames);
code for automatic recognition of files improved drag&drop, to decide whether to split or concat);
Largely improved error checking:
now the program checks the users' system and AppleScript version before run (some people still seem to try to run the program on OS 10.1, which is not possible);
now the program warns if the user tries to split or concat a file that contains a "resource fork".
the program now also checks if there is enough space available on the output disk and warns when a user is attempting to write to a read-only folder or disk.
the program now warns the user if he/she attempts to split or concat a folder, a disk or an OS X application (which in reality is a folder);
The program is now shareware.
This is because the program now is widely popular (esp. as post-processing agent for MacPAR deLuxe), yet I only received very few donations. But this program will not be expensive: ANY donation from $1 to $1.... will do! I leave it entirely up to you what you want to give for this program. That doesn't mean that people who don't sponsor the program can no longer use it. All split and concat functions will remain available. There will be no time limitations. But sponsors will be rewarded with more functionality, to make working with the program more fun. Without a registration code the users will be frequently reminded (with beeps and dialogues) of the possibility of sponsoring.
Certain options will now only work for sponsors:
the program will open the resulting file after a concat process;
the program will automatically quit after doing its job;
you can now switch off the beeps and warnings (e.g. when a file must be overwritten); some users complained about these hindering beeps and dialogues after a succesful proces. Now (for sponsors only) the program will perform a fast and fully silent process without any noisy beeps or buttons that must be pressed by the user.
