[users at bb.net] [Foreign Sender] Re: Detailed log of RemoveDirectory step's failure?

[Greg Bullock]

Thank you for that comment, Vasily.

It turns out that indeed there is a (deeply nested) file with a full 
path of 265 characters.

I'll modify the build to reduce the nesting depth and report back 
whether this resolves the problem.

Regards.
Greg
