Metadata.size
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The read-only size
property of
the 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.
workingDirectory.getFile("log/important.log", {}, function(fileEntry) {
fileEntry.getMetadata(function(metadata) {
if (metadata.size > 1048576) {
fileEntry.remove(function() {
/* log file removed; do something clever here */
});
}
});
}, handleError);
