It is quite rare to exceed 259 characters for a file path name. If that is needed, ViceVersa PRO supports long path names exceeding 259 chars.
To enable this in a specific folder use the prefix "\\?\".
For example, to allow paths longer than 259 characters in c:\folder\backup\ use \\?\c:\folder\backup\ as source (or target, or archive folder) in ViceVersa PRO.
Using "\\?\" permits a maximum path length of approximately 32,000 characters composed of components up to 255 characters in length.
To specify a UNC path, use the "\\?\UNC\" prefix.
For example, "\\?\UNC\<server>\<share>".
