What should be done if it is difficult to remove files from an image?

Using compression techniques, such as Zstandard, is an effective way to manage files within an image when removing files proves to be challenging. Compression can help reduce the size of the files and create a more efficient storage system without having to alter or extract the files directly. This approach is particularly useful when you're unable to delete or extract data due to limitations of the tools or methods being employed.

Zstandard is a modern compression algorithm that offers a balance between speed and compression ratio, making it suitable for applications with various processing specifications. By compressing the files, you can optimize storage and may even address issues stemming from space constraints.

While considering the other options, ignoring the issue does not resolve it and could lead to further complications down the line. Switching scanners might help in specific circumstances, but it does not directly address the underlying file management issue. Increasing image size limits could provide temporary relief, but it is typically not a sustainable solution and might introduce new challenges without actually resolving the difficulty of file management within the image. Compression, on the other hand, offers a direct and practical solution to the problem of handling excessive files effectively.
