Files with the .DOC extension contain formatted text documents stored in a proprietary binary format of Microsoft Word. Storing format was different for each version of the Microsoft office suite. Currently, it has been displaced by an open format based on XML, in order to provide mobility (DOCX).
Files with the .DOCX extension contain formatted text documents, possibly with graphic elements, stored in a native format of Microsoft Word, since its 2017 version. DOCX files are an element of Office Open XML format specification.
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 DOC file after converting to DOCX may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from DOC to DOCX 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 DOC to DOCX does not meet your expectations, you can simply try to find on the Internet a different version of your file in DOC format, properly converted to a DOCX file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file DOC the desired result was not achieved, you can try to change the format of DOC file to other than DOCX. 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 DOC file converted by someone else, and the attempt to convert it to DOCX 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 DOC file in its original format (without conversion to DOCX file). Such a solution will be difficult to implement, but it certainly will give the best result.
