As outlined under the Data Protections in the macOS Catalina 10.15 page, Apps must now get your permission before directly accessing files in your Documents and Desktop folders, iCloud Drive, and external volumes, so you’re always in control of your data.


In ACDSee Photo Studio for Mac 5, the macOS will prompt to let you confirm the access permission as you browse to those locations first time after launch the program. Note those folder locations may be automatically browsed on launch as part of folder discovery, so you may be prompted on launch even though you have not explicitly selected any folder.


Please click OK to allow the access


If you inadvertently click the "Don't Allow" button, ACDSee will not show any content in those locations. And the OS will not prompt the user for permission again.


To allow access again, please use the steps below

- Go to System Preferences > Security & Privacy > Privacy > Files and Folders

- Find ACDSee application , and check the applicable boxes to allow access.
