  • Allows searching files based on their metadata.
  • Creation of metadata templates to eliminate, add or modify standard or customized metadata to facilitate the modification of metadata in the documents.
  • Possibility of creating an unlimited number of metadata templates to establish corporate policies by department or area.
  • Continuous protection in real time against leaks of confidential information through metadata without user intervention.
  • Allows to tag the documents with customized metadata.
  • Allows you to configure metadata modification in PDF with signature. The protection of the signed PDFs can be activated so that MetaClean does not modify the metadata and the signature is invalidated.
  • Compatible with cloud storage: Google Drive, OneDrive, etc.

  • Example 1 (Windows Platform):
MetaCleanCL.exe -h 

   Action parameters:
   -h --> Display help.
   -d [full_path_to_input_files_directory] --> Local directory or network shares containing the documents to be processed.
   -watchDir [full_path_to_input_files_directory] --> Monitors local directory or network shares in order to automatically add or remove metadata from documents. If -watchDir parameter is set then -d and -f parameters are not allowed.

   -search [metasearch-N] --> Among the files found in the specified directory, look for those files whose metadata match those specified in the file, this file is located in the installation directory.
   -f [full_path_to_input_file] --> Input file, MetaClean CL will process the input file. If -f parameter is set then -d, -r and -type parameters are not allowed.
   -metadata [template-N|remove|export|view] --> Parameter to select an action to perform from documents metadata:
      template-N: Set custom metadata to documents. In order to set the required custom metadata, go to MetaClean Command Line install path and edit the file.
      remove: All metadata will be removed from files.
      export -fileExp [full_path_to_excel_file]: The metadata from documents will be exported to an Excel file.
      view: Views the metadata from the specified file.

   Optional parameters:
   -r                                      --> Searches for files recursively into input directory.
   -o [full_path_to_output_files_directory]--> To keep the original files as they were before MetaClean processes them and set the path to write new files.
   -protectPdfSigned [true|false]          --> Set true to protect signed PDF files from metadata modifications, default value is false.
   -log [full_path_to_output_log_filename] --> Writes the results of each action in a output log file.
   -logSize [limit]                        --> Limits the maximum size of the log files, in case the file reaches this size MetaClean CL will create a new one up to a maximum of 5 files. This means that the log files can be overwritten.

This example displays a description of each of the available options.

  • Example 2 (Windows Platform):
MetaCleanCL.exe -f "C:\Documents and Setting\myDocs\example1.pdf" -metadata view

This example displays metadata from the specified input file.

  • Example 3 (Windows Platform):
MetaCleanCL.exe -d "C:\Documents and Setting\myDocs" -r -type pdf,mm -metadata remove -o "C:\tmp" -log "C:\tmp\clean.log" -logSize 1

The following command line remove metadata from PDF, image, audio and video files located in “C:\Documents and Setting\myDocs” directory and subdirectories, the cleaned files are saved in “C:\tmp” folder and the process log is saved to a set of 5 files of 1 Mb, with the filename pattern: clean_NUMBER.log

  • Example 4 (Windows Platform):
MetaCleanCL.exe -watchDir "C:\wamp64\www\myDocs" -r -type pdf,mo -metadata remove -protectPdfSigned true

This example removes the metadata from PDF (excluding PDF signed files) and Microsoft Office files from the specified directory and subdirectories, as recursive flag is set (-r). When this process has finished, MetaClean will monitor the “C:\wamp64\www\myDocs” directory (and subdirectories) in order to automatically remove metadata from new or updated documents. The process output will be displayed on the terminal. (No log files will be created).

start /B MetaCleanCL.exe -watchDir "C:\wamp64\www\myDocs" -r -type pdf,mo -metadata remove

To run the process in the background (Windows)

java -jar MetaCleanCL.jar -watchDir "/wamp64/www/myDocs" -r -type pdf,mo -metadata remove &

To run the process in the background (Linux/Unix)
