SharePoint Fingerprinting Wizard - File Filtering

Use the File Filtering page of the SharePoint fingerprinting wizard to use file type, file age, file size, or a combination of properties to determine which documents are fingerprinted.

Steps

  1. To filter based on file type or file name, mark Filter by Type/Document Name, then list the types of files to be fingerprinted, separated by semi-colons.
    • Optionally use the “*” or “?” wildcards. For example, “*.doc; *.xls; *.ppt; *.pdf”.
    • Click File Types to select the type of files to include in the scan from predefined categories such as Office Documents or Bitmaps.
  2. Use the Except field to list the file types to exclude from the scan, separated by semi-colons. Wildcards are permitted here as well.

    Click File Types to select the type of files to exclude in the scan from predefined categories such as Office Documents or Bitmaps.

  3. To filter based on file modification date, mark Filter by Age, then use the radio buttons to select a time period (24 months, by default).
  4. To filter based on file size, mark Filter by Size, then select one or both of the following options:
    • Mark Scan only files larger than, then select a file size from the spinner. By default, all files larger than 1 KB are scanned.
    • Mark Scan only files smaller than, then select a file size from the spinner. By default, all files smaller than 100,000 KB are scanned.
    Note: Files larger than 100 MB are fingerprinted for exact- matching. Two binary fingerprints are created: one with the first 100 MB, and another with the first and last 5 MB. When a large file is received, the first and last 5 MB are sent to analysis. They are compared to both of the fingerprints above to search for a match.
  5. Click Next to continue.
