These files cannot be opened in pre-2018 versions of Origin (Origin 2018 and newer versions retain the ability to save files in the older OPJ format).

Origin 2018 introduced a new Unicode-compliant (UTF-8) project file type - the OPJU file. If you are collaborating on a report or manuscript, pack the Viewer along with your project file, and the lead author can copy and paste your data and graphs where needed, into the document. Double-click to run the executable, drop your Origin project file onto the Viewer and you are ready to go. In addition, because the Viewer can be carried on a thumb-drive, it allows for impromptu sharing of Origin data and graphs in meetings and classroom settings. Non-users will find the Origin project's 'folder and file' structure to be be intuitive and easy to navigate. The Viewer does not require installation and it is quickly mastered, making it an ideal way to share your Origin data with colleagues who may not be Origin users. This updated Viewer supports Origin's newest OPJU project file and window file (OGGU, OGWU, OGMU) formats, as well as the older OPJ and OGG, OGW, and OGM file formats. The Origin Viewer 9.6.5 is a freely distributed, standalone application that allows viewing and copying of information contained in Origin project files and Origin window files, on computers that do not have Origin installed.
