If you use pick or pickMultiple (not pickAndStore), on a file located in a cloud source like dropbox, and you do not have storage credentials configured, then the Filestack link will be a symbolic link back to the file where it is stored in Dropbox. So, if the file owner moves or deletes that file from their dropbox account, the Filestack link will become broken.
The v3 picker stores files by default. If you have not configured your own S3 or other storage option, the v3 picker will store the files to Filestack's S3 buckets. Symbolic links will not be generated unless you explicitly tell it to generate them by using
preferLinkOverStore in your picker code.
Someone from our team will get back to you shortly.
