Epiq AI can process files in their native forms, extract text and metadata, and generate PDFs for document annotations, redaction, and production exports.

​
Folder structure

Epiq AI preserves the original folder structure of your native documents as part of the upload.
  • Epiq AI traverses all documents recursively under the top-level folder.
  • For each file, Epiq AI records the folder path in the file’s metadata.
  • This preserved path can be used to understand the original organization of the documents.

​
Container files

Some files act as containers that store other files or attachments. Epiq AI opens these containers and processes their contents.

​
Archive and store containers

For archive and store types such as:
  • .pst
  • .rar
  • .7z
  • .gz
  • .zip
  • .z
  • .bz2
  • .alzip
Epiq AI:
  • Extracts embedded files from the container.
  • Performs extraction recursively:
    • If a container includes another container (for example, a ZIP file inside a ZIP file), Epiq AI also extracts and processes the nested contents.

​
MIME-based containers

For MIME-based formats such as:
  • .eml
  • .ics
Epiq AI:
  • Extracts attachments from the file.
  • Processes the attachments as documents, subject to supported file types and processing rules.

​
OCR and image text extraction

Epiq AI uses Optical Character Recognition (OCR) to extract text from images so that image-based content can be searched and analyzed. OCR is applied to:
  • Standalone image files. For example, image files uploaded directly.
  • Images embedded in documents such as:
    • PDF files
    • Word documents
    • PowerPoint presentations
    • Excel workbooks
Text detected through OCR is stored as document text and becomes available for searching and review alongside text extracted from non-image content.
