I'll chime in on the question content, as it sits after editing. As a new user, you're missing some of the context underlying the issue.
The purpose of the site is to build a knowledge base of solutions that can help many users; it isn't a personal help line. It also isn't fiverr, where people post a requirement and hope someone will be motivated to develop a solution for them. It's more the case that people submit questions or problems that other people might also have, that can build the knowledge base, in exchange for potentially getting an answer for themselves.
Sample Code Requirement
This is not a "give me code" kind of site. If we provide a solution, it's important for the OP to understand it so they can solve the next variation themselves.
Your providing code in the question is not an absolute requirement in every case, but it's requested for a reason. Asking the poster to make an effort to solve the problem is one way to help them learn by being involved in the solution, and it gives them some skin in the game. It also leads to their identifying specific coding issues that are more appropriate in scope for a question than requesting "application development".
Trivial command lines and batch files are often provided in an answer even without the OP including sample code. This is especially true if it may not be obvious to a novice where to start, it could be useful to many readers, and a knowledgeable user can knock out an answer quickly.
At the same time, we don't want people asking for free development of a mini-application, especially of use only to the OP. Those kinds of questions are always considered too broad or out of scope.
In between these extremes is a gray area subject to community discretion.
The community needs to weigh how useful the question and answers will be to other readers, which is the purpose of the site. A question that is a collection of requirements for completing a complex task tends to be very user-specific, so answers often won't be helpful to anyone else. Even if the answers contain some useful techniques, other readers won't be able to readily find them.
We also need to consider the scope. The intended scope is a single, bite-sized problem that can be fully answered and explained in a limited number of paragraphs. Solving a single, specific, on-topic coding issue can fit that model. A problem with multiple, complex requirements may not be a good fit.
In addition, a simple question is likely to attract a solution. Something requiring significant development, debugging, and documentation is much more likely to languish on the site, unanswered by the busy people who volunteer their time.
Another reason complex coding questions tend not to be a good fit is that the answers tend not to contain detailed explanation understandable by a novice questioner. So other readers who might need someone to create such code for a similar problem aren't likely to understand how to adapt the answer to their own needs. Encouraging such questions would end up littering the site with single-user solutions that are unusable by other people who might need something similar.
Poor Fit Questions
We get questions that are not a good fit for the site -- too ambiguous or poorly explained, too broad, too user-specific, etc. Sometimes those get answered, and the answer might even solve the problem for the OP. But the question remains a poor fit for the site. Those questions can get closed even though they have an answer.
Which brings us to your question. To me, your question in its current form is borderline. It's not trivial, it's a pretty unique, single-user requirement, but it has the gist of a problem others might share. The question could benefit from refinement.
Frame it in a more general way to make the nature of the problem (merging and sequencing) more recognizable. Make the requirements more explicit. Perhaps the best way to do that is to include a mock-up (visual) of the before and after file contents. Leave out the ambiguity ("probably"), and provide a specific requirement.
