What does it indicate when there is a blue line in front of a file before you click file?

When there is a blue line in front of a file, it indicates that the data is pending and still able to be edited. This visual cue signifies that the file is in a state where modifications can still be made, allowing users to update or change the content as necessary. The presence of the blue line implies that while the data is not yet finalized, it is also not complete, thereby providing an opportunity for further adjustments or additions before it is fully processed or locked down. This understanding is essential for effective data management, as it guides users in knowing when they can interact with the file and how they should proceed with any required edits.
