When doing webkitRequestFileSystem in window.PERSISTENT option in Google Chrome, where on my filesystem do files get written? I'd like to drop files there and have Chrome interact with them while I'm building and debugging this app.
回答1:
For me, at least on Mac OSX, they're stored under /Users/USERNAME/Library/Application Support/Google/Chrome/Default/File System for me. If you're using profiles, there will be profile directories instead of Default. However, each origin's saved files/folders are obfuscated under directories that won't be easy for you to interact with.
For debugging the Filesystem API, you have a few options:
- Use this extension to view/remove files.
- See the tips here: http://updates.html5rocks.com/2011/08/Debugging-the-Filesystem-API
That includes viewing stored files very easily using the
filesystem:URLs. - Drop the Filesystem Playground demo (http://html5-demos.appspot.com/static/filesystem/filer.js/demos/index.html) into your origin. You can use that to view/rename/delete files/folders easily.
- Chrome DevTools now has support for the Filesystem API for viewing the files stored under an origin. To use that, you will need to enable the Developer Tools experiments in
about:flags, restart, hit the gear in the devtools (lower right corner), and enable the 'FileSystem inspection' under the experimental tab.

Just for completeness: on linux it goes into ~/.config/google-chrome/Default/File\ System/

On Windows XP, it is here: c:\Documents and Settings\USERNAME\Local Settings\Application Data\Google\Chrome\User Data\Default\File System\.
On Windows 7, the location is C:\Users\USERNAME\AppData\Local\Google\Chrome\User Data\Default\File System.
It's not very useful to browse it because file and dir names are obfuscated (but content in files is unchanged).
As ebidel wrote the best way is using browser of filesystem: urls that incorporated into Chrome. It's excellent! You can get the url using fs.root.toURL() where fs is a FileSystem object that you get, for example, from window.webkitRequestFileSystem().

Seems like the filesystem storage is encoded to prevent exactly what was trying to do. I ended up writing a very simple file manager available here. Start up any web server (I like mongoose for its 0 setup) and go to the /filemanager.html route

I saved a file called log.txt on MAC
It ended up at ~/Library/Application\Support/Google/Chrome/Default/Storage/ext/panbljeniblfmcakpphmjmmnpcaibipi/def/File\ System/iso/p/00/
with file name 00000 and no ext

If you are using MAC OX, and you have more than one profile on your chrome, or you cannot find default in the path, replace default with profile. But depending on number of profiles you have, it could be profile 1, profile 2, etc
