Casedo uses files on your local machine. These files can be synced to your own cloud account (e.g. Google Drive, DropBox etc.). It’s about expediency, and getting work done. Casedo is installed locally so you don’t need an internet connection to upload documents, you don’t have to wait for your documents to upload over a poor connection, and your documents are as secure as you make them. You can just get on with it.
