FileSystemEntry: isFile property
The read-only isFile
property of
the FileSystemEntry
interface is true
if the entry
represents a file (meaning it's a FileSystemFileEntry
) and
false
if it's not.
You can also use isDirectory
to determine
if the entry is a directory.
Warning:
You should not assume that any entry which isn't a file is a directory or vice versa.
There are other types of file descriptors on many operating systems. Be sure to use
both isDirectory
and isFile
as needed to ensure that the
entry is something you know how to work with.
Value
A Boolean indicating whether or not the FileSystemEntry
is a file.
Examples
This example shows how this property might be used to determine whether to process the entry as a directory or file. If the entry is neither, an error handler is called with an appropriate message.
if (entry.isDirectory) {
processSubdirectory(entry);
} else if (entry.isFile) {
processFile(entry);
} else {
displayErrorMessage("Unsupported file system entry specified.");
}
