<p dir="auto">All open files are written on 'Save All', causing unnecessary triggers of change watchers, for example.</p>
<p dir="auto">Due to <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="28729672" data-permission-text="Title is private" data-url="https://github.com/atom/atom/issues/1690" data-hovercard-type="issue" data-hovercard-url="/atom/atom/issues/1690/hovercard" href="https://github.com/atom/atom/issues/1690">#1690</a> now when you call <code class="notranslate">window:save-all</code>, all the files opened by the editor get touched. That is definitely not a good idea, since it can trigger file watcher for files that didn't change, and it can cause performance problems when you have a lot of files open and you are working on a slow disk, or with third party programs that monitor your filesystem (Dropbox, anyone?)</p>
