Ah well, I was hoping maybe the XML used a switch on that EXE... An image will should either me 1 large file (over 2GB) or it may use multiple spanned-files in 2GB parts.
WinRE's boot.wim is just a WinPE. So all those folders you see are from that. I highly doubt the TWinRERecoveryReminder.exe creates folders in the way you mention, although it is quite possible that it prompts to insert a disc.
Do you have any other partitions on this system?
