GOAL:
How to find out what is the Progress database extent file signature
GOAL:
What is a file signature?
FIX:
The file signature identifying the type of a file is normally contained in the first 20 bytes of the file. For example a Windows Bitmap file with the file extension .bmp would contain "424D" hexadecimal in the first 20 bytes.
The Progress database extent uses the 8 first bytes to store the file signature. When opening (use a hexadecimal tool) a Progress 9.1D .d file the following number will appear on the first 8 bytes:
00 00 00 00 fe 7f 01 00
The number above is the file signature for all .d, .db, .bi, for version 9.x and 10.x.
