# Deprecation: #62864 - DataHandler->include_filefunctions deprecated

See [forge#62864](https://forge.typo3.org/issues/62864)

## Description

The public property `->include_filefunctions` has been marked as deprecated.
It has not been formally defined and was only created dynamically in the code.

## Impact

In the history of the core this property has never been used (read). Extensions might have used it.

## Affected installations

All installations running extensions that rely on reading this property. Currently no affected extensions are known.

## Migration

If your extension needs to know whether the BasicFileUtility has been instantiated in DataHandler it
could use `$datahandler->fileFunc instanceof TYPO3CMSCoreUtilityFileBasicFileUtility`
