File names in Topicscape

I noticed a file name changed from "Agenda.doc" to "Agenda`22`.doc"

"I dragged a file from Windows Explorer to the occurrence list of a Topic Centre. When I look at the file's name at the foot of the details panel, I can see that it has changed. It used to be "Agenda.doc" and now it is "Agenda'22'.doc". The occurrence is called Agenda, though. Why did it change?"

This is a normal function and results from the need to avoid duplicate filenames when files are stored in your Topicscape's folder. If you drag it out again, the name will be reset to the original one, "Agenda.doc" in this case.
