Join split files to a single file with your Windows machine.
File Joiner is a very simple and easy to use application that will combine split files (with extensions: .001, .002, .003, etc.) back into one file. Files with extension .001 (001, 002, ... 00n) are parts of a bigger file that was split so they could be sent over newsgroup, file hosting or some other service which limits maximum size of files that can be uploaded. File Joiner is developed in C++ as 32bit & 64bit version.
It looks like you have to select the files to join manually and then possibly make sure they are in the correct order in the file window. It seems a lot of work compared to the "click on .000 or .001 file and go" program that I was using but which doesn't seem to work in Windows 7 (no surprise there).
