HTTrack 3.48-19
GUI: Yes (not commandline version)
Build / Local Site Sructure: Site-structure (default)

Consider a site with the following strucure:

www.somesite.com/images/001/
www.somesite.com/images/002/
www.somesite.com/images/003/

where each folder "001", etc. has several images in it named similar to:
001-01.jpg, 001-02.jpg, etc.

HTTrack creates the local structure properly but the files are all named:

001-01.jpg_;
001-02.jpg_;
etc.

Is there a way to tell HTTrack to name the files properly?
Thanks.
