Question

I did this autocmd but it broken synchronization detection,

vim.api.nvim_create_autocmd("WinResized", {
pattern = "*",
callback = function()
require("mini.files").setup({
windows = {
width_preview = vim.o.columns - 41,
},
})
end,
})

There are several issues here:

• WinResized is not the right event for this as it triggers whenever regular Neovim window is resized. You'd want VimResized to detect when terminal's instance is resized.
• Executing setup() is a bit too much in this particular context. In general, executing setup() for any 'mini.nvim' module is recommended to 1) enable plugin with its initial config; or 2) perform an action that is specific to setup() (like create mappings). For "on the fly" config modification it is usually enough to modify config field (in this case MiniFiles.config) directly. See more "Setup" section of "General principles".
• There is MiniFiles.refresh() to update the config of the currently shown explorer.

Taking into account all of that, the following setup works:

require('mini.files').setup({
  windows = {
    preview = true,
    width_focus = 37,
    width_preview = vim.o.columns - 41,
  },
})

vim.api.nvim_create_autocmd('VimResized', {
  callback = function()
    local new_width_preview = vim.o.columns - 41
    -- Update current explorer (if any)
    MiniFiles.refresh({ windows = { width_preview = new_width_preview } })
    -- Update config for all future explorers
    MiniFiles.config.windows.width_preview = new_width_preview
  end,
})

Thanks a lot for fast reply and for the solutions. With this config, I can replace oil.nvim already. Thanks
