How can I have my default app open the file that I double click? It works fine when I right click on the file and select Open but not when I double click. ---

It normally works by default. If not, right click the file, use the Open With menu and set the default app from there. If that still doesn't work, which type/extension is it, and which program are you trying to use with it? I'm assuming the latest version of Opus, but if not then please let us know. ---

Windows 10 updated my machine yesterday so perhaps this is a problem related to that. I use both LibreOffice Calc and Writer. Tonight, when I double-clicked a Calc doc, then a Writer doc from the Opus file list all seemed to be well. I made a few edits, then proceeded to save. That's when the following window appeared which I do not understand. ![image](https://resource.dopus.com/uploads/default/original/3X/4/6/4698ca45dc1530b8e91acb9bddddd82b9e85089b.png) I'm not sure whether my attempt to paste an image there worked, so I will simply copy the text of that message as follows: Document Could No Be Locked The lock file could not be created for exclusive access by LibreOffice, due to missing permission to create a lock file on that file location or lack of free disk space. [Open Read-Only] or [Cancel] This wasn't a total disaster. I merely save those docs to different filenames, moved the originals to a temp folder, then renamed the temp docs back to the original filenames. This, however, is a scenario I don't want to repeat whenever I launch from Opus. I concede that Opus is quite new to me as of a few weeks and there may be some setting I missed. Len Miller ---

Moments ago, I used the right-click then Open technique to launch. However, still the same problem as above when I went to save the file. However, if I exit the file, LibreOffice presents a page with a list of several topics, one of them being Recent Files. Launching files from that repository allowed me to edit and save as normally expected. Len ---

That error message is coming from LibreOffice rather than Opus. I don't think it's related to what this thread is about. ---

I'm trying to open a .jpg file that I use IrfanView as the default but I expect any other file format to be a similar problem. ---

> [@azobel](#): > > I'm trying to open a .jpg file Is it opening in the Opus viewer instead? If so, you probably chose that during installation, but it's easy to turn off: [How to stop the Opus image viewer from being used by default](https://resource.dopus.com/t/how-to-stop-the-opus-image-viewer-from-being-used-by-default/1366)
