Files with the VSTX extension belong to the category of graphic files. What do VSTX files contain? Files with the VSTX extension contain technical drawing templates. They are used by software called Visio from Microsoft.
File with VSD extension contains drawings and diagrams created using Microsoft Visio and saved in binary format. VSD uses lossless compression algorithm similar to LZW. VSD is a proprietary format; it was replaced by VDX format in 2010, and by VSDX and VSDM in 2013.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the VSTX file after converting to VSD may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from VSTX to VSD to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting VSTX to VSD does not meet your expectations, you can simply try to find on the Internet a different version of your file in VSTX format, properly converted to a VSD file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file VSTX the desired result was not achieved, you can try to change the format of VSTX file to other than VSD. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your VSTX file converted by someone else, and the attempt to convert it to VSD on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the VSTX file in its original format (without conversion to VSD file). Such a solution will be difficult to implement, but it certainly will give the best result.
