Thanks Bob, you're right. The macro later steps leftward from the end of tAlternative looking for the first '\' . I temporarily added a Text Display to show this character. I also used your suggestion, but simply with Add Text.
It seems there are 2 invisible characters at the end of every Excel cell, probably CR LF, because the display continues on a new line. And in a text editor a Backspace just jumps up to the right of the visible string.
Thanks both. I'll get back into this tomorrow. The only reason I'm moving the 504 GB C:\Docs is because I'm down to 8% free space on the 750 GB C: drive. But if the shortcut issue proves as time-consuming as it is beginning to look, then I may re-consider and seek other options. For example, maybe I could compromise and just move the 160 GB C:\Docs\My Videos and drastically limit the number of affected shortcuts.
A macro that steps through a folder identifying LNK files, opens its Properties and then changes the target doesn't sound too difficult. Probably gets harder if a large number of sub-folders involved.
BTW, I soon expect to be ordering a new PC (which I'll run in parallel for a while). Given that I'm not into hi-tech media hardware, (I spend most of my time making videos), would you recommend Windows 7 or 8?

Pleased to report that the first script you suggested is looking good! Tested on a folder containing a small subset of my 10,000 and it worked OK. Next step will be to add a few subfolder levels.
