I've finally figured out "how" Yamaha Tyros/PSR keyboard Registration Bank (RGT) retrieve (call up) associated: Style, Voice, Multipad, and Lyric Text (.txt) files.
I've recently discovered a terrific (free downloadable) Windows utility program called "File Alyzer" which allows one to view the content details of a Yamaha Registration Bank (RGT) file. I've learned that, not only are the associated (style, voice, multipad, lyric text) file 'NAMES', but the FILE PATH (to where that file is located) is saved in Reg as well. This 'file path' also includes the specific device drive letter. This means that whatever associated files are called up via Registration must REMAIN STORED in a specific location (device location, and folder name hierarchy) in order for the Reg to successfully retrieve them. Because of this, succesfully using Registration Bank Files on any other keyboard than the one the Registration Bank file was originally created on, will be challenging at best.

HERE Thru the above "File Alyzer" software utility program, I've now discovered the 'drive letter' Yamaha has assigned for each of the following Tyros2's file storage device locations:
User Memory: Drive letter - C
Hard Drive: Drive letter - E
USB1 & USB2: Drive letter - I
I've also discovered that Yamaha assigned Tyros1's floppy drive as drive letter "A", the PSR3000's card as drive E, and PSR3000's USB as drive letter "F".
In addition: Thanks to the FREE German Yamaha arr-keyboard utility program called "Drive-Convert", it's now possible to re-assign the remote device's "drive letter" to which a specific Registration (1-8) looks for its associated style, voice, mulitpad, or text file. It's important to note though, that upon device drive letter reassignment, that the associated style etc files must reside in the "root directory" of that device.

HERE The above "Drive-Convert" program however is limited to re-assigning the following drive letter locations on/or between ONLY the current model Yamaha keyboards: Tyros2 and PSR3000. Unfortunately it's not possible with "Drive-Convert" to convert from the Tyros1's floppy drive (A:/) to Tyros2's USB (I:/).
From PSR3000 Card (E:/) to USB (F:/)
From PSR3000 USB (F:/) to Card (E:/)
From Tyros2 HD (E:/) to Tyros2 USB (I:/)
From Tyros2 USB (I:/) to Tyros2 HD (E:/)
From PSR3000 Card (E:/) to Tyros2 USB (I:/)
From PSR3000 USB (F:/) to Tyros2 USB (I:/)
Ok, from what I've learned above, I've now CONCLUDED (if I want to ever use my REGS on another KB other than my Tyros2 alone) that I NEED (on my Tyros2) to store ALL custom styles, voices, multi-pads, or text files (which will be utilized in registrations) in the "ROOT DIRECTORY" of the USB (I:/) drive. I hope my posting will benefit others here as well.
