Files include no more than 100,000 records each. Batches of records that include more than 100,000 records will be split into multiple files with successive files extensions. See file extensions.
File retention and expiration
Your files are retained both on the server and in the WorldShare interface for 90 days. You can download a file multiple times.
Collection Manager output files older than 7 days will be compressed (i.e., zipped) in order to improve performance. Compressed files are given the .zip extension but retain their original file name (e.g., metacoll.OCWMS.new.D20170612.T141740.1.mrc becomes metacoll.OCWMS.new.D20170612.T141740.1.zip).
