Differences from S3a B_GEN

==========================

testnodeinfo: Commented out - dunno what a node info is.

testdeviceinfo: TVolumeInfo structure doesn't contain a version member, test commented out

testfileinfo: TEntry structure doesn't contain a version number, test commented out

testrename: 

Long filenames are allowed

Test rename of directories across directories: This works - used to return AccessErr

testDelete: Attempting to delete a directory returns KErrBadName instead of an AccessErr

testUnique: Seeking ie. random access on a temp file is now valid - used to return E_FILE_INV

testVolumeName:

SetVolumeLabel will set the volume label to any string of 11 chars or less.

testDir:

All directories require some matching criteria eg: "*" or "*.txt"

Test filenames starting with '.' eg: \\.ZZZ are now legal.

test.Printf(_L("Test filenames starting with 05/E5\n"));

0xE5 at the start of a filename => a VFAT entry

0x05 at the start of a filename returns an error under NT

testMedia: Not implemented

testNodeInfo: Not implemented

testFileInfo: Changed argument values.

Paths are allowed on Z:

Asking for info on a drive that does not exist return KErrBadName not NoFileSystemErr

test.Printf(_L("Test weird filenames\n"));

All weird names are now valid except _L(" ");

All short names are valid except "" and "\\"

All long names < 256 chars are valid

Dots within a filename are valid

Test Make directory:

Long directory names are now valid < 256 chars

Test read of zero bytes:

No longer returns any EofErr. Instead reading zero bytes will zero the length of the buffer.

Test set file date:

Old test data commented out because NT fails on dates < 1601.

Interface to Format has changed (will probably be changed back shortly) Test commented out

Differences between WINS and EPOC platforms

===========================================

NT will register time differences of less than 30 microseconds FAT needs ~ 1/10 sec

The filename _L("...") -> KErrAccessDenied on NT but is ok on VFAT

0x05 at the start of a filename is disallowed by NT. VFAT will accept 0x05 but doesn't translate it into a 0xE5.

NT will match a single '?' to the _L(".") directory. VFAT never sees '.'
