Just think of another option, a flag(date) can be included within the file (in a field perhaps) for comparison purpose. If the flag(date) for file(s) in the folder > max flag(date) in existing data, then load the data into QV from the "new" file.
I just wonder what should happen in a special case:
- You have Files A, B, C in your directory - You read A,B and C in the first reload - In the second reload you still have A,B and C - nothing should happen. - File B is being deleted - In the third reload also nothing happens - File B is created again in the directory: What should happen ?
