As with others, I am running PL/SQL Developer 15 in a RemoteApp configuration (similar to Citrix). I can see that we are able to use the command line parameters to change the location of the Preferences folder and PLS-Recovery but there are also other settings that are made to files that appear in the root of the user's PLSQL Developer 15 roaming folder. Is there any way to redirect the entire folder structure using a command line parameter?
