Long story real short...
Across the intra-net, from S01, I deleted a bunch of log files in Computer S02's D:\Logs. Said some things to myself, didn't help the recovery any.
Remembering that all three computers have free-version Teamviewer [which works via Google Chrome] and pay-for version Resplendence's Undeluxe -- I Teamviewer-ed from S01 into S02, used S02's copy of Undeluxe, found the directory Logs, had it save all recoverable files into S02's C:\hold. Using both Teamviewer and the intraNet, I copied S02's C:\Hold into S01's D:Logs and S03's D:\Logs, and finally copied files into S02's C:\Logs.
I regularly [almost bi-weekly] clean out Undeluxe's pointers, so that recovery of recent deletes won't be so cumbersome. Undeluxe makes a tiny text-file pointer to each and every deleted file.
If anyone really cares, can give further details, can give specific answers to specific questions.
