Method, sources and limits
One copy = photo count × average size. All copies = one copy × total copies. Optional headroom multiplies each by (1 + percent ÷ 100).
Logical size is not allocated disk space. Include metadata, edits, videos and other files in your estimate if needed. This tool cannot verify independent backups, successful copying or recovery.
