Google Drive:

• Open Google Drive on web based browser like Chrome
• On each of the folders if you see a person symbol it’s shared, if you don’t see the symbol its not shared
• For each folder -> click SHARE -> Advanced -> Check which user has view rights and which user has edit rights -> Disable options to download, print, and copy for commenters and viewers -> Prevent editors from changing access and adding new people.
• For each folder -> click SHARE -> Advanced -> SHARE SETTINGS -> Change -> Check settings there are 4 to 5 options
• Note -> Even if your folder is not shared, files inside it can be in shared mode – This seems to be a big missing feature in Google Drive. There is no clear way to check this in one go for all files and we individually need to check each file. Workaround: Write Java code using Google Developers API to check this: https://developers.google.com/drive/
