Thanks for prompt response.
I tried the following (it worked fine):

(My NAS is mapped to L: drive in the last example).
The only problem is the %20 character for all those cursed names with spaces. I once used a utility that automated the copy of system filenames (by also inserting by substitution the %20 characters in all spaces).
Is there any quicker method?
I guess better to automatically rename the offending (with spaces) files is the preferred method and more permanent solution without future hickups.
