Imagine a tree, displaying the contant of a zip file, drag and drop files inside the archive, between archives and to and from Explorer and using only a part of the relative path in the zip file. This means constant renaming. Please explain your point that the name field must be this size . By the way, would it be possible to access the name field and extra field short before the adding and extacting ? Gerard.
