getFileAttribute <filename_string> <attribute>

setFileAttribute <filename_string> <attribute> <boolean>

Get and set the attributes associated with a file.

The get function returns true or false depending on the state of the specified attribute.

The set function sets the state of the individual attribute specified (leaving other attributes as they were).

The valid <attribute> values are:

#readOnly

#hidden

#system

#directory

#archive

#temporary

#normal
