I am working on a website that is using HTML5's Filesystem API to write some files to a temporary file system. Is there any way I can use the Chrome Developer tools to inspect the files I have written?
If you go to chrome://flags and enable "Enable Developer Tools experiments", then go to the Experiments tab in the Dev Tools settings, there's one named "FileSystem Inspection" that might work. I haven't tried it, though.
Filesystem inspection is no longer available.
I couldn't find an official announcement, but it looks this filesystem API is going to be soon deprecated by Chrome as it was never accepted as a standard by W3C and nowadays (Jan 2017 with v.55) Google Chrome is the only web browser using it.
It cost me long time to search the inspector, as other people shows in their blog . I am using v.63, it's no longer exists .
but their is another method to do it with web terminal . maybe you can do like this http://www.htmlfivewow.com/demos/terminal/terminal.html
