Thanks for the info; Paul K. of your support group gave me the same answer
I, however, being ignorant, brashly did the following instead, and am awaiting whatever cataclysm is imminent:
I used Mark Russinovich’s junction.exe tool to replace
programfilesfolder\bigfix enterprise\bes server\wwwrootbes
with a junction that points to the copy of the directory i made on the other, emptier drive
e:\wwwrootbes
after copying the additional recently created
programfilesfolder\bigfix enterprise\bes server\wwwrootbes
contents into that latter and renaming the folder to get it out of the way. So, after reverting the registry value changes (not really needed, i surmise) and starting back up all the BES services i’d killed beforehand, i’m told things seem back in order (minus the disk space problems)
