Term: File size

Definition:

The size of a file including all its components and tracks, expressed in units based on a byte (kilobyte [KB], megabyte [MB], gigabyte [GB], etc.)

File size, when written to a file system, may be reported as slightly higher than the actual size because a file system may round the size up to include any unused space left over in the last block used by the file.

Changes in expected file size can be an indicator of data change or loss in the file so can be a first sign that additional analysis is needed.
