The read-only size property of the {{domxref("Metadata")}} interface specifies the size, in bytes, of the referenced file or other file system object on disk.

Value

A number indicating the size of the file in bytes.

Examples

This example checks the size of a log file and removes it if it's larger than a megabyte.

js
workingDirectory.getFile(
  "log/important.log",
  {},
  (fileEntry) => {
    fileEntry.getMetadata((metadata) => {
      if (metadata.size > 1048576) {
        fileEntry.remove(() => {
          /* log file removed; do something clever here */
        });
      }
    });
  },
  handleError,
);
