## Review summary

User reviews show two opposing experiences. A minority finds that the app provides basic OTG/file-management functionality and can handle simple tasks, with occasional praise. However, the majority criticize an overwhelming ad experience that dominates navigation and disrupts use, reporting ads after every tap and on many screens. This ad load is linked to reliability problems, including loading stalls and non-functionality. Overall, while a few users report usable results, the consensus is that the app is impractical due to heavy advertising.

### Pros

- Basic OTG/file-management functionality works for some users
- Effective for simple tasks
- Occasional positive feedback (e.g., 'Excellent', 'great') from a subset of users

### Cons

- Excessive and intrusive ads, including on every screen or after each action
- Ad load hinders usage and can make the app feel non-functional
- Occasional reliability issues like getting stuck on loading screens
- Strong negative sentiment in reviews, with some calling for removal from the Play Store
