I'm developing a chrome app with the capability to handle files. I need to copy these files to the app, which I believe stores it in the app's sandbox.
But where are these files, like on my disk?
Here's where I get access to the filesystem:
fs = null oneGig = Math.pow 2, 30 # 1GB window.webkitRequestFileSystem window.PERSISTENT, oneGig, (_fs) -> # on fs init fs = _fs console.log fs.root.fullPath #=> "/" obviously not right (e) -> # on fs error console.log e
Followed by this code to actually write the files.
fs.root.getFile songObj.md5, create: true, (fileEntry) -> fileEntry.createWriter (fileWriter) -> fileWriter.onwriteend = (e) -> console.log 'Song file saved!', fileEntry, e # Where the hell on disk is my file now? fileWriter.onerror = (e) -> console.log 'fileWriter.onerror', e fileWriter.write songObj.blob , (e) -> console.log 'fileEntry.createWriter error', e , (e) -> console.log 'fs.root.getFile error', e
I've had some bugs in my file handling and want to be able to easily inspect what is going on, as well as clean things up if necessary. And I can't seem find anywhere in the docs that it says files go. And this especially frustrating since I'm have files just vanish after coming back to the app a few days later.
They go into a "sandbox" which isn't easy to inspect. You might want to instead use the new chrome.fileSystem chooseEntry function (http://developer.chrome.com/apps/fileSystem.html) with the "directory" option and also "retainEntry" to get access to write to a normal directory on your computer, so that you can see the files and have them not be cleared out when you clear your browser cache, etc.
