WASHINGTON — A federal judge on Friday ordered the State Department to finish preparing roughly 1,000 pages of Hillary Clinton’s emails for release by Nov. 4, a more protracted timetable that means the bulk of Mrs. Clinton’s emails that were uncovered by the Federal Bureau of Investigation will not be released until after the election.

In August, the judge, James E. Boasberg of Federal District Court, raised the prospect of a flood of Clinton emails being released during the final weeks of the campaign, when he ordered the State Department to accelerate the release of nearly 15,000 new emails.

But Judge Boasberg acknowledged the burden for the department’s lawyers in reviewing thousands of emails, as well as responding to multiple lawsuits under the Freedom of Information Act that seek documents relating to Mrs. Clinton, her aide Huma Abedin, and the Clinton Foundation.

Under the order issued on Friday, in a lawsuit brought by the conservative group, Judicial Watch, the State Department will release 350 pages of emails by Oct. 7, 350 pages by Oct. 21, and another 350 by Nov. 4. After that, it will produce 500 pages a month. Judge Boasberg summoned the lawyers for another status report on Nov. 7, the day before the election.
