Suggestions for Optimizing the Open Method

[XiXi-2024]

Issue Description
In the Open method, when there are issues such as an invalid path or name conflicts that prevent the file from being opened, the program still proceeds with initializing the indexes. This results in unnecessary resource consumption, as the initialization is pointless when the file cannot be opened.

Proposed Improvements

1. Reorder the logic to prioritize attempting to open the file first.
2. Validate the file path before attempting to open it to avoid unnecessary disk I/O operations.

If I’ve misunderstood the issue or if the description is not clear enough, please feel free to point it out. If everything looks good, I’d be happy to submit a PR to implement this improvement😄.
