1. I recently removed all symbolic links, returning all files to their default paths (including all files under “C:\ProgramData”, and “C:\Program Files\AnyTXT Searcher\config.db”);
2. The configured index interval is still “every 4 hours”;
3. Execute a “manual full re-index” after undoing all symbolic links, and then restart the computer (first time);
4. Wait for the fault to reappear. This “index (faulty)” lasts about 1.5 hours;
5. Restart the computer immediately after completing the previous step (for the second time, it has been more than 1.5 hours but less than 4 hours since the last time the computer was restarted and indexing was completed).
Test results: After restarting the computer for the second time, AnyTXT started to behave like a “full re-index” again.

All files under “C:\ProgramData”, as well as “C:\Program Files\AnyTXT Searcher\config.db” are in the exclusion list of Shadow Defender, and the above test was performed when the system entered shadow mode.
My assumption: Since the above path is not affected by Shadow Defender, AnyTXT may somehow and somewhere record the last index time. Eventually whenever I start or restart the computer, automatic indexing should be done at the interval I configure. Start automatically (the appropriate start depends on the last index time or the last change index cycle) rather than with every system startup.
In addition, I also found that the duration of automatic indexing after each system startup ranges from about ten minutes to about 1.5 hours.
