The web drawings saved with Microsoft Visio are saved as VDW files. These files are saved to Microsoft Sharepoint which allows the user to view the file through internet browser.
The method for saving the file as web drawing is somewhat different as compared to Visio drawing. The VDW files have ability to save multiple pages in single file along with hyperlinks and other features of Visio drawing. The main difference between Visio drawing and web drawing is that web drawings have the function to connect to external data source. Rendering of some elements in Visio drawing is not similar to web drawing.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .VDW file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .VDW file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .VDW file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .VDW extension. Directly on this website you can find a solution of the most common problem with the .VDW file – that you do not have on your computer the appropriate program to open the file.
