Posting Etiquette

  1. Ask the main part of your question in the title. This should be concise but informative.

  2. Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.

  3. Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.

  4. Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

Is it better to check if a file exists before trying to load it, or to try to load it, and catch the error and move on? (lemmy.ml)

You should do both. Creation and catching of exceptions can be an expensive process and even if the check for the file succeeds the loading of the file may not in which case you'll need to handle the exceptions anyway.
