Additional Features

This features have no corresponding Megacmd command, but they are infered from the existing ones

Count

Show the amount of elements in a folder or that match the query mask. E.g.

    final long amountOfFilesAndDirectories = sessionMega.count("remote/path");

But what if you want to filter that counting and it a Predicate to, for instance, just get the files and not the directories.

    final long amountOfFiles = sessionMega.count("remote/path", FileInfo::isFile);

Exists

This is pretty much the equivalent of java.io.File.exists. It checks if the remote path or mask indicates any non null response. E.g.

    sessionMega.exists("remote/path/filesprefix*.ext");

Export with an expiration date

With a premium mega account, you can export and generate public folder links by setting the option expire date.

    LocalDate expireDate = LocalDate.of(2020, 9, 2);
    final ExportInfo exportInfo = sessionMega.export(exportFolder)
            .setExpireDate(expireDate)
            .call();

or you can just specify a duration using TimeDelay.

    final ExportInfo exportInfo = sessionMega.export(exportFolder)
        .setExpirationTimeDelay(TimeDelay.of(
             Period.ofYears(3).plusMonths(11).plusDays(15)
         ))
        .call();
