Assumptions:
- a perfect integrity of the reference index table (always update the reference index table before using this tool!)
- relevant soft reference parsers applied everywhere file references are used inline

Files may be missing for these reasons (except software bugs):
- someone manually deleted the file inside fileadmin/ or another user maintained folder. If the reference was a soft reference (opposite to a TCEmain managed file relation from "group" type fields), technically it is not an error although it might be a mistake that someone did so.
- someone manually deleted the file inside the uploads/ folder (typically containing managed files) which is an error since no user interaction should take place there.

Automatic Repair of Errors:
- Managed files (TCA/FlexForm attachments): Will silently remove the reference from the record since the file is missing. For this reason you might prefer a manual approach instead.
- Soft References: Requires manual fix if you consider it an error.

Manual repair suggestions:
- Managed files: You might be able to locate the file and re-insert it in the correct location. However, no automatic fix can do that for you.
- Soft References: You should investigate each case and edit the content accordingly. A soft reference to a file could be in an HTML image tag (for example <img src="missing_file.jpg" />) and you would have to either remove the whole tag, change the filename or re-create the missing file.
