Notes about the JOINED file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The JOINED file type is primarily associated with 'HJSplit' by Freebyte.com. HJSplit is a popular set of freeware file-splitting programs created by Freebyte.com in collaboration with various programmers. HJSplit supports many platforms (Windows 3.x/95/98/ME/2000/NT/XP, DOS, Amiga, Java, etc.). All versions are compatible with each other and allow you to exchange files between these different platforms. E.g. a file split on the Amiga can be joined on Windows 2000 and vice versa. If you do not specify an output file extension or there is none in the .001 file header the program automatically adds .JOINED to the reconstructed file.
