Changing permissions to a folder does not change the permissions for files and subfolders already in the folder. This can be frustrating when you need to change permissions to large number of files or folders.
To make multiple changes in file permissions for your OpenDrive files you can select multiple files at once (within the application), access the properties window for one of the files, change the permissions, and select OK or apply. This can be done for multiple folders as well, but files and folders will need to be selected separately.
It is important to keep in mind that this will need to be done at each folder level where you would like to change permissions, as the files and folders will not inherit the new permissions. The only time permissions will be inherited is when files and subfolders are initially uploaded.
