Convert files

This dialog is activated by selecting the Convert files... command from the File Menu. It can be used to convert single or all *.opju files from the folder specified in the Path edit line, if the box All is checked, to the .opj file format.

The *.opju file format, introduced in Origin 2018 can only be imported by QtiPlot on Windows, provided that a recent OriginLab version is installed on your computer (even as an evaluation or demo version). In this case QtiPlot can use the COM interface installed by OriginLab in order to convert the .opju files to the older .opj file format, which, afterwards, can be imported directly by QtiPlot, also on other operating systems than Windows, like macOS or Linux.
