@huchenme This prompt is to make sure you are working with the desired workspace with the LeetCode files. Several users ask to have a way to configure where to save those files before.

Regarding to your problem. The root cause is that when the VS Code is reloaded, the execution is terminated. Let me think about how to resume the execution after the VS Code is reloaded.

[ghost]

I think there is a conflict between this configuration and the "output folder".
"output folder" with absolute path may be a good choice.
（感觉这个设置和之前的"output folder"选项有点重复和冲突了，但"output folder"只能设置相对路径，也许用绝对路径的"output folder"替代这个新选项会好一些。另外，vscode reload是因为自动打开了文件夹，那可不可以只是设置路径，而不自动打开文件夹来避免reload。）

[jdneo]

@ANGIANAPR

I can rename for better understanding about the real meaning of outputFolder. But the question is, if you don't open that folder into the workspace, how will you manage the LeetCode files in that folder?

[huchenme]

@jdneo as a user, I don't really need to manage or know the LeetCode folder. Before this issue I don't really know how this extension works, just simply click the tab icon, pick a problem and start coding. This extension was working without the popup showing.

[ghost]

@jdneo

That‘s a problem. How about that...you can add a "Reveal in Explorer" shortcut in editor and manage the leetcode files in the system explorer rather than in the vscode explorer.

[jdneo]

@huchenme Actually this is a really hard decision to make to tune the experience.

In your case that you don't care about the existence of LeetCode folder, while we do have other users who want to:

• manage their files in a centralized way.
• open the leetcode files that he previously solved at anytime.

There must be some way to satisfy most of the users' preference, but I'm just thinking about it. Please feel free to let me know if you have some suggestions. Or PR will be much better.

Thanks.

[jdneo]

@ANGIANAPR

That would be something worth consideration! I'm thinking that in the dropdown list, I can add a new item, like Just open the file in editor, if this is chosen, the extension will only open that file.

[huchenme]

@jdneo you could have a button / command to open LeetCode directory for those users while for most user, just use default location to save the files and they do not need to know there is such folder exists.

[jdneo]

@ALL

Split this issue into two work items:

• User can either open the folder or just the file when selecting the problem User can either open the folder or just the file when selecting the problem #373
• Considering to merge 'leetcode.workspaceFolder' and 'leetcode.outputFolder' into one single setting Considering to merge 'leetcode.workspaceFolder' and 'leetcode.outputFolder' into one single setting. #372

This issue will be closed. Thank you for the discussion and participation here, which are very inspiring. Please feel free to leave your comments into the separate issues if you have more ideas.

Thanks.
