How to use chrome extension filesystem api?

Question

Hi as example i want to read

c:/x.txt

as text

and write? is there any example about chrome.fileSystem ?

Notice : I don't want to ask the path of file to user

Answer 1

Already answered at Chrome Extension HTML Filesystem Access, I think. Note that chrome.fileSystem only exists in apps, not extensions.

To just read files, try asking for the file:///* host permission.
