File Storage is the actual size of your recording files. This can be measured in kilobytes (kB), megabytes (MB), or gigabytes (GB) or terabytes (TB).
When you run a batch process with Kaleidoscope Pro, metadata information, such as species ID, recorder settings, and notes are written to a database file (db-batch.wdb). This database file, when updated to a Managed Cloud Account database, allows the metadata to be searchable. In Kaleidoscope Pro pricing, database storage refers to the uncompressed storage space used in db-batch.wdb. You can see the actual storage used once the database is uploaded. The likelihood of exceeding the 1GB of metadata limit is rare and would require terabytes of data with over 1M files.
