791816 - [DeviceStorage] File overwrite on b2g device

Status: RESOLVED FIXED

(Firefox OS Graveyard :: General, defect, P3)

Description

[[e-mail] [:onecyrenus]]

Got an "Unknown" error while trying to write to a file on the sdcard which was already present. 

Possibly we would want a separate error case for this scenario.

I would venture that we should check if a file exists prior to attempting to write, and if it does exist we through "already exists" error or something like that.

Or maybe would be better to write, catch the error, and then verify if the file already exists.  Probably easier on the hard drive.
