Bulk Check (module for Omeka S)

IMPORTANT: This module is deprecated and has been replaced by the module Easy Admin and won’t be updated any more. The upgrade from it is automatic.

New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.

Bulk Check is a module for Omeka S that allows to check your metadata and files and to fix some common issues.

Checks and fixes that are doable:

  • list files in the file system (original and thumbnails), but not in the database
  • remove useless files in the files directory (moved to files/check)
  • list files in the database, but not in the file system (for original and thumbnails)
  • copy original files from a directory, for example after a disk crash or an inadvertent deletion; files are copied via the hash, and they can be anywhere in the directory or in subdirectories of the source path.
  • rebuild derivative files
  • remove empty directories in file system (original and thumbnails, mainly for module Archive Repertory)
  • check and update file size of media (required to fix Omeka installed before Omeka 1.2 (omeka/omeka-s#1257), or after a hard update of files)
  • check and fix sha256 hashes of files
  • check and fix positions of media (start from 1, without missing number)
  • check and stop dead jobs (living in database, but non-existent in system)
  • check the size of the database table of sessions and remove them
  • check the size of the database table of logs and remove them
  • check and fix the encoding (iso-8859 to utf-8) of resource values and page contents


This module requires the modules Generic and Log.

See general end user documentation for installing a module.

  • From the zip

Download the last release from the list of releases, and uncompress it in the modules directory.

  • From the source and for development

If the module was installed from the source, rename the name of the folder of the module to BulkCheck.

Quick start

Go to the menu "Bulk Check", select your process, set your options if needed, and click the submit buttons. The results are available in logs currently.


  • Output results as tsv (/files/check/tsv_date_time.tsv) as BulkExport or in a table (done for missing file; to do for all processors).
  • Check files with the wrong extension.
  • Add width/height/duration as data for image/audio/video to avoid to get them each time (ready in modules Iiif Server and Image Server).
  • Remove old logs.
  • A main cleaning task.


Use it at your own risk.

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.
