How is my storage consumption calculated?

Storage usage is calculated based on both file sizes and metadata overhead for directories/files. Each directory counts as 64 KB, each file as 128 KB - in addition to actual file size.

Example: Storing 1,000 PDF files (3 MB each) in 20 directories results in ~3.05 GB total storage. Calculation:

= File-Size           + Directory-Metadata + File-Metadata
= 3.145.728.000 Bytes + 1.310.720 Bytes    + 131.072.000 Bytes
= 3.278.110.720 Bytes
≈ 3,05 GB
