.WDR File Extension

The wdr file extension is associated with the Psion Series 3, a family of portable computers (PDA) with SIBO (Symbian) operating system.

The wdr file stores printer driver for Psion Series 3 SIBO system.

.WDR file format is deprecated and this file format is no longer supported.

Currently, .WDR file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.

How to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .wdr file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
