# Breaking: #78552 - Lowlevel LostFilesCommand parameters changed

See [forge#78552](https://forge.typo3.org/issues/78552)

## Description

The existing CLI command within EXT:lowlevel for detecting and removing files within uploads/ which are not referenced by TYPO3
has been migrated to a Symfony Console command.

The command previously available via `./typo3/cli_dispatch.phpsh lowlevel_cleaner lost_files` is now available via
`./typo3/sysext/core/bin/typo3 cleanup:lostfiles` and allows the following CLI options to be set:

`--update-refindex` \- updates the reference index before scanning for lost files. If not set, the user is asked if the task should be run
`--exclude=uploads/mypics/,uploads/psa` \- a list of paths of files to exclude within uploads/
`--dry-run` \- do not delete the files but only list the files that are not connected to the TYPO3 system anymore

The PHP class of the old CLI command `TYPO3CMSLowlevelLostFilesCommand` has been removed.

## Impact

Calling the old CLI command `./typo3/cli_dispatch.phpsh lowlevel_cleaner lost_files` will result in an error message.

## Affected Installations

Any TYPO3 instances using the lowlevel cleaner for finding and deleting lost files.

## Migration

Update the CLI call on your servers to the new command line and available options as shown above.
