* Sets a semi-colon separated list of filters to filter-in or filter-out
|

* certain types of files when the contents of this directory are requested
|
|
* via a GetFilesAndDirectories() call.
|
|
*
|
|
* Currently supported keywords:
|
|
*
|
|
* * filter-out-sensitive
|
|
* This keyword filters out files or directories that we don't wish to
|
|
* make available to Web content because we are concerned that there is
|
|
* a risk that users may unwittingly give Web content access to them
|
|
* and suffer undesirable consequences. The details of what is
|
|
* filtered out can be found in GetDirectoryListingTask::Work.
|
|
*
|
|
* In future, we will likely support filtering based on filename extensions
|
|
* (for example, aFilters could be "*.jpg; *.jpeg; *.gif"), but that isn't
|
|
* supported yet. Once supported, files that don't match a specified
|
|
* extension (if any are specified) would be filtered out. This
|
|
* functionality would allow us to apply the 'accept' attribute from
|
|
* <input type=file directory accept="..."> to the results of a directory
|
|
* picker operation.
