What is the 'ExtData' folder for?

TIA

Ext - Ext Data folder - stores 006-D0952-01.bin, 006-D0952-02.bin, 006-D0952-03.bin, 006-D0952-04.bin, 006-D0952-05.bin, 006-D0952-06.bin, 006-D0952-07.bin, 006-D0952-08.bin, 006-D0952-09.bin, 006-D0952-10.bin files which contains special font for not alphabet languages likes Herbew, Thai, Arabic, Vietnamese.
ExtData folder - also stores for some device with MTK chipset files ARC.BIN, BEE.BIN, 006-D1221-00.bin. 006-D1221-00.bin + GPS Chipset Type M HotFix Data software which updates by webupdater and ARC.BIN & BEE.BIN files which store current info for GPS software metioned above.
Look better at:
<Path>.System/G2S</Path>
<FileName>D2329100A.G2S</FileName>
