Problem when moving folder containing a reaper project and sfz instrument in windows

[bernardgeyer]

I use Reaper in Windows, and I wanted to have in the same folder a Reaper project and an .sfz instrument. The samples used by the sfz instrument are in a subfolder called soundfiles,

I thought that this was an usefull way to share a project with my students.
But when they copied my folder and try to use my project with sfizz, the samples were not loaded.
After that I found out that when I move the folder (with everything inside) on another place in my computer, the same problem happen.
The problem remains the same if I code directly the folder in sample= instead of using default_path=soundfiles/

The students using Mac OS X don"t have this problem.

Everything works also correctly when using sforzando instead of sfizz.

Any idea ?
