.RProj files not opening directly into RStudio

[dighenilesh]

Hi, I updated my R (4.1.1) & Rstudio (1.4.1717) versions today. Below is my session info. The issue I am facing is that any old or new .RProj extension file are not automatically recognized by RStudio. The only way I can open this file is by going into RStudio and go with file > open File > .RProj

In the past, I could double click on the .RProj file and open Rstudio with all the relevant files associated with that project. Can someone help? Thanks.

Hi @dighenilesh,
Welcome to the RStudio Community Forum.

It sounds like your default file association has been "lost" or changed.
Type "file association" in the Windows search box, go to the first link (in Settings), scroll down to .Rproj file extension, and then add RStudio as the default app for that file type. After that, a double-click on an .Rproj file should take you straight to that project in RStudio.

Of course, RStudio projects can also be accessed easily from the Projects pull-down list (top right of the RStudio main window).
