Supported file types for processing

• Processing support for .xfa pdf, .pdf web forms, includes extraction of text, metadata, and imaging. Some workflows may require specific workarounds:
  • Native redactions are not currently supported. Workaround: Image the file first, then apply redactions.
  • The download PDF action, using the Natives file type, is not currently supported. Workaround: After selecting the PDF mass action, use either the Original Images or Produced Images file type or export the files as .pdfs using Import/Export.
• Relativity performs Optical Character Recognition (OCR) on .pdf files during processing. Relativity handles a .pdf portfolio, which is an integrated .pdf unit containing multiple files, by extracting the metadata and associating it with the files contained in the portfolio.
• Relativity extracts embedded text that exists within .pdf files. If Relativity does not detect text, it performs Optical Character Recognition (OCR) on .pdf files during processing.
• Relativity handles a .pdf portfolio, which is an integrated .pdf unit containing multiple files, by extracting the metadata and associating it with the files contained in the portfolio.

• The OCR output for processed CAD files can vary significantly.

For information on compressed files, see the Supported container types table.

• Relativity only supports .dbf 3 and .dbf 4 files.
• Relativity does not support the following database formats:
  • VisualFoxPro
  • VisualFoxPro autoincrement enabled
• Relativity uses Microsoft Excel to extract text from .dbf file types. For details on .dbf file type handling, see Excel files.

• Original electronic email data (.eml file types) are parsed and stored inside a personal storage table (.pst files.) If the email contains embedded electronic email data, the email data is also parsed and stored in the personal storage table. The processing engine reads tables, properties, and rows to construct an .msg (Outlook message item) file from a .pst file. The .msg file format supports all rich metadata inside an email in a personal storage table. The original electronic email data is not preserved.
• S/MIME-encrypted and digitally-signed emails are supported.
• Even though the .emlx file type is supported, the following partial .emlx file extensions are not supported:
  • .emlxpart
  • .partial.emlx

• Processing supports .e01 and .ex01 files for the following operating and file systems:
  • Windows—NTFS, FAT, ExFAT
  • Mac—HFS+
  • Linux (Ubuntu)—EXT2, EXT3, EXT4
• Deleted files that exist on an .e01 and .ex01 (disk) image file are skipped during processing, with the exception of recycle bin items, which are processed with limited metadata.
• Encrypted EnCase files are not supported. You must decrypt EnCase files prior to processing them.

For details on .e01 file type handling, see Multi-part forensic files.

Excel version 2.0 through the current product version is supported. See Excel files.

If you save a Powerpoint or Excel document in pre-2007 format, .PPT or .XLS files for example. and the document is read-only, we use the default known password to decrypt the document, regardless of whether or not the password exists in the Password Bank.

.hwp

Hangul word processing files 1997 up to 2010 are supported.

.heic

All metadata extracted from .heic files, including but not limited to Exchangeable Image File Format (EXIF) metadata where present, is available for mapping to workspace fields. These fields can be found in the field catalog under the Metadata field type and have a prefix of HEIC/.

Relativity extracts metadata and attachments from multipurpose internet mail (MIME) file formats such as .mht and .eml during processing.

.one

• During ingestion, Relativity extracts embedded items from OneNote files.
• All child objects are extracted as separate documents.
• Text extraction takes place during discovery (and not OCR.)
• The Password Bank supports OneNote files.
• RelativityOne supports OneNote 2003+ and 2007+.

• PowerPoint 97 through the current product version is supported, including the dual-format 95/97 version.
• Modern Comments are supported with Relativity Text Extraction.

If you save a Powerpoint or Excel document in pre-2007 format, .PPT or .XLS files for example. and the document is read-only, we use the default known password to decrypt the document, regardless of whether or not the password exists in the Password Bank.

The text extracted from Project files is from the Gantt chart view and includes Task Notes.

Processing supports any text file whose bytes are ASCII or Unicode text. Files are assumed to be in UTF8 if a Unicode BOM is not found. Files not in a Unicode format with characters outside the ASCII range may experience issues with text extraction.

Relativity does not support Instant Bloomberg .xml files.

Relativity does not support multi-part .cab files.

Relativity does not support Password Protected .cab files.

For compressed container files, keep in mind the following:

• Relativity supports multi-part .rar files. You do not need to combine multi-part .rar files before processing them.
• Relativity does not support multi-part .zip, .tar, or .7z files. Self-extracting .rar files are also not supported.
• Depending on how .rar files are encrypted, extraction may be impacted. See Password-protected .rar files for more information.
• Very large container files may impact processing speed. One workaround is to extract the files from the container and process them from a new processing set.
• When working with archives, there is no limit to the number of layers deep processing goes to extract data. It extracts until there is no more data to be extracted. Inventory, however, only extracts data from first-level documents. For example, if you have a .zip file within a .zip file that contains an email with an attached Word document, Inventory only extracts up to the email. Additionally, .zip files within .zip files may impact performance.
• Zip files do not store time zone information for the CreatedOn, LastModified, and LastAccessed fields. When extracting files, time stamps are only meaningful if you know the time zone in which the .zip file container was created. Relativity extracts file metadata and updates the CreatedOn and LastModified fields if available. Otherwise, CreatedOn defaults to 1/1/1900, and LastModified reflects the worker's local time zone. The LastModfied and LastAccessed fields will usually match.
• Zip files do not store character encoding information, which can be problematic when such characters use non-Unicode encoding. In this case, you may see garbled characters in the names of extracted files and folders, especially when the originating locale differs from the processing region configured for the Relativity instance. For example, given a .zip file originating in a Russian locale, with filenames encoded using Windows-1251 and processed on an instance set to US/English, the .zip's extracted file and folder names may be unrecognizable. To maximize the potential for successful extraction, confirm your instance is configured with a processing region that is appropriate to your geographical location. Contact your Customer Success Manager for questions regarding this and other instance settings.

Relativity supports processing both single and multi-part non-encrypted .ad1 files. For encrypted .ad1 files, only single part files are supported. For multi-part .ad1 files, you must decrypt the files prior to processing. See Multi-part container for more information.

For Outlook meeting invites, the email that is sent with the meeting invite (the .msg file) will have a sent date that reflects when the sender sent out the meeting request. The resulting calendar file that is then added to the user's Outlook calendar (the .ics file) will not include a sent date, as the date doe not apply to the calendar file itself.

.nsf

Relativity supports Lotus Notes version 10 and earlier.

See Lotus Notes for more information.

.mbox is a standard format, in which case it does not matter whether you're using a Mac folder format or a Unix file format.

• Relativity assigns duplicate hash values to calendar invites, as it does with email messages and other documents.
• Relativity supports Teams data conversion to RSMF out of PST. See Short message conversion for Microsoft Teams for more information.
