# [File Check] [Document] Menu

Use this command to conduct file check on file not updated since the last time it was saved. Conduct this check immediately after the document is open.
This is a check on whether there are any problems with the data in a document or in a binder. If there are problems, the document cannot be saved.
When there are no problems, the message "File check ended with no problem." appears.
The following message appears for the different types of problems.

- Problem with the page or with an object on the page:
  "Error is found in the following object Page XX."
- Problem with the original data:
  "Error is found in the following object.
  Document: XXX
  Original data: XXX"
- Problem besides the above mentioned cases:
  "Error is found in the following object.
  Object other than page and original data"
