Disclaimer: You of course must purchase iCloud storage separately through Apple (or use their 5gb free tier plan). You are not required to use iCloud with File Cabinet Pro if you do not want to (this is an opt-in feature). Your purchase of File Cabinet Pro does not come with any iCloud Storage, File Cabinet Pro only provides a client-side front end for you to use.
In this brief tutorial I will show you how you can use iCloud with File Cabinet Pro. File Cabinet Pro provides a user interface for you to drag and drop files to and from iCloud. Configuring File Cabinet Pro to work with iCloud is easy.
Step 1: Make sure you have iCloud Drive enabled on your Mac.
In order for File Cabinet Pro to work with iCloud, you must have iCloud Drive enabled on your Mac. To verify that you have iCloud Drive enabled on your Mac, go to System Preferences and select iCloud. Make sure iCloud Drive is checked.
Step 2: Enable iCloud in File Cabinet Pro.
Now that you have iCloud Drive set up in System Preferences, the next step is to enable iCloud in File Cabinet Pro. Click the File Cabinet Pro icon in the menu bar to bring up the application’s main window. Now click the gear button at the bottom of the window to bring up the context menu and select “Settings.”
Now File Cabinet Pro’s settings window will appear:
At the top of the settings window, you will see a checkbox that says, “Configure iCloud.” After you click the “Configure iCloud” checkbox, a save panel will appear allowing you to create File Cabinet Pro’s root directory in iCloud Drive. You can create File Cabinet Pro’s root directory anywhere in iCloud Drive, however, it is recommended that you create the directory at the root level of your iCloud Drive folder (alongside the iCloud folders for other applications like TextEdit). Once you choose the location in iCloud Drive using the save panel, File Cabinet Pro will create its root directory in iCloud Drive.
Step 3: That’s it! Start using File Cabinet Pro with iCloud Drive!
Once you have completed steps 1 and 2, you will see two buttons appear in the main window of File Cabinet Pro. One button has the title “Local” and the other has the title of “iCloud.” You can use these buttons to switch between File Cabinet Pro’s local and iCloud directories. You can also drag files over these buttons to to take advantage of File Cabinet Pro’s innovative drag and drop feature:
