Will deleting a sample file affect a project that uses it?
Yes, deleting a folder or file containing a sample used in your project will cause playback problems. Projects manage necessary data (sounds, samples, etc.) on the SD card. It is explicitly stated that the SD card contains various data for the device, and these files should not be removed or manipulated inappropriately, as this could lead to malfunctions. If source resources are deleted, the project will no longer be able to access the necessary audio data for its operation.
