# ConvertFromOldVersion Method of FRDocument Object

> ConvertFromOldVersion method of the FRDocument Object in the ABBYY FineReader Engine API — Loads the contents of an FRDocument from a folder saved by previous FineReader Engine versions; for FRE 12 documents, use LoadFromFolder instead.

This method loads the contents of the [FRDocument](/fine-reader/engine/api-reference/document-related-objects/frdocument) object from the specified folder, where it should have previously been saved by the [SaveToFolder](/fine-reader/engine/api-reference/document-related-objects/frdocument/savetofolder-method) method.

<Warning>
  Use this method to load the document saved only by the previously supported versions of ABBYY FineReader Engine. If you want to load the documents saved by ABBYY FineReader Engine 12, use the [LoadFromFolder](/fine-reader/engine/api-reference/document-related-objects/frdocument/loadfromfolder-method) method instead.
</Warning>
