I looked at that, but the FInfo.Flags of my locked file is 0.

Apparently this finder "name locked" bit is independent of the actual 
lock bit accessed via ParamBlock.fileParam.ioFlAttrib & 1.

Just's method looks like it will work, but I've realized I need to 
interrogate the lock bit first (gonna put it back after munging the 
file), so I used this an excuse to clean up a one-shot extension 
module I wrote once and call it "myfileutils."

Thanks though.
