How to extract png from dat file?

[Raccoon Sam]

that particular file contains indeed these strings in pairs, just before a bunch of entries that appear to be 0x27 bytes in width:
all_ef_s01_02_1 and all_ef_s01_02.png,
all_ef_s01_03_1 and all_ef_s01_03.png,
all_ef_s01_01_1 and all_ef_s01_01.png,
all_ef_s01_01_2 and all_ef_s01_01.png,
all_ef_s01_01_3 and all_ef_s01_01.png,
all_ef_s01_01_4 and all_ef_s01_01.png

But the data doesn't look like graphics, more like models or something. I'm not familiar with the game but I don't believe these files contain sprites.
