OKIOCAM does not have any in-built storage so files cannot be stored within in.
Files created in the OKIOCAM Snapshot and Recorder app are automatically saved locally to whichever directory is configured as the Library Folder in the Settings menu (the directory can be changed).
Files created using the OKIOCAM Google Chrome extensions (OKIOCAM Stop Motion, OKIOCAM Time-Lapse, for example) can be stored either to your Google Drive or locally on your computer. You can configure the Google Chrome extensions to save files locally by selecting On Local Device in the Settings menu. However, please note that you will need to use the Download Selected Files (accessible through Review Mode) feature to download a copy of your files to your computer’s physical storage.
