- 1.5.4. Can Dia open Visio .vsd files?
No, it can't. Visio file format is a completely proprietary and undocumented file format. So it is really difficult to write code to read it. The now-defunct Software Bazaar offered a bounty of several thousand dollars for reverse-engineering the Visio format. We really would like to be able to do so.
An easier alternative would be to make a Visio plug-in that will allow conversion. Other programs have already done this for their proprietary formats. If somebody were to make such a script, we could set up a public server to do conversions.
With Visio 2002, it has become possible to export Visio diagrams as XML (.vdx). Microsoft, in their infinite generosity, has even published the Schema. Ian Redfern has made use of this, and a VDX importer/exporter is part of Dia as of version 0.96.
Ian Redfern is working on decoding the Visio format. If you have any interest in converting Visio files, please give him your assistance. Valek Filippov made a little research of the VSD/VSS file format. At some point Ian is going to hook the results to a VDX importer. Right now vsdump can be useful for dumping images embedded into VSS stencils to subsequent converting them into Dia sheets.
