Many applicants focus on the bank statement and ignore the rest of the file. A short-stay application is stronger when the documents explain one clear travel story.
The question is not only whether money exists. The file should make it easy to understand why you are going, why now, how long you will stay, who is paying, where you will stay, and why you are expected to return.
If there has been a previous refusal, the next file should not simply repeat the old one. It should address what changed and what evidence now supports the trip.
