How to Open, Edit, & Convert DOP Files

A file with the DOP file extension is most likely either a DxO Optics Pro Correction Settings file or a Schneider Electric/Telemecanique HMI project file.

Some DOP files may instead be used to hold custom PDF export settings, XML-based Directory Opus Application files, or Digital Orchestrator files used with Voyetra Turtle Beach's now-discontinued Digital Orchestrator audio software.

How To Open a DOP File

DxO Optics Pro Correction Settings files are used by DxO Optics Pro to store information about changes made to a RAW file with that program, but they aren't intended to be opened directly.

In other words, when you open a RAW image file with DxO Optics Pro, make changes to it, and then export the image as JPG (or whatever format you choose), a DOP file is created alongside the conversion that stores the changes you made. So long as the DOP file stays in the same folder as the RAW image, your settings will be retained the next time you open the RAW file in DxO Optics Pro.

If your specific DOP file is a Schneider Electric/Telemecanique HMI (human machine interface) project file, you should be able to open it with Schneider Electric's Vijeo Designer or Delta Electronics' Screen Editor.

The software Directory Opus, a Windows Explorer alternative, uses DOP files too, but they're just stored in the application's installation directory and aren't meant to be opened or used manually. However, since they're plain text files, you can open one with your favorite text editor for editing or for reading the code.

DOP files that are PDF export settings may be used with other programs but the only ones I know of is PTC's Creo Parametric and Creo Elements.

The last version of the Digital Orchestrator program was released in 1997 and I can't find an official download/purchase link, so it's likely that your DOP file is not in this format.

If you're sure it is, you must have that program in order to open it. You can read a little about it on the Digital Orchestrator Pro page at the Videogame Music Preservation Foundation.

Other DOP files may have nothing to do with any of these applications. If you're not sure what format it's in, I suggest opening the DOP file with Notepad++ to view it as a text document, which can sometimes help you find out what type of file it is (document, image, video, etc.) or what program was used to create it.

Tip: Still can't open your DOP file? You might check the file extension again to be sure you're not confusing your file with another that has a similar file extension, like a DOC, DOT (Word Document Template), DO (Java Servlet), or DHP file.

If you find that an application on your PC does try to open the DOP file but it's the wrong application or if you would rather have another installed program open DOP files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert a DOP File

Most file types can be converted using a free file converter, but I don't know of one that supports any of these DOP formats.

One thing you can try is opening the DOP file in the program that it belongs to, and then use the File > Save as or Export menu (if there is one) to convert the DOP file to a new format.
