Maybe I am totally mistaken.
Assume I always use the latest sqlite_shell.exe program. I do not want to 
change anything in this program, 
then I cannot connect to my virtual file system which is written in C and 
stored in "myExtension.dll".
In contrast loadable extensions can be used.
For me loadable extensions and virtual file systems are somehow similar both 
communicate via a specified interface with sqlite (although on different 
levels). But the usage of loadable extensions seems more convenient and I 
wonder why?
Best Martin

do you mean, without changing anything in C? What is myExtension.dll written 
in? Can't it call sqlite3_vfs_register during its initialization? Igor
