Index.of.finances.xls.39
I was going through some legacy financial archives from the late 90s/early 2000s, and I came across a strange entry in a folder list:
DataHoarder_99
Does anyone know what the .39 suffix means?
If I rename to .xls or .xlsx , Excel just crashes. Hex dump shows 39 00 00 00 at offset 0x1A, which might be a version marker.
