In the previous post I speculated that the counts of file names in the corpus might be skewed due to the number of disks cracked by 4am. In this post I separate them out.

As in the previous post, I'm just dealing with the 6,998 disks meeting certain tests of a “normal” DOS 3.3 VTOC and CATALOG. Of those disks, 1,278 have the string (4am crack) in their disk name.

The most common file names in the (4am crack) disk CATALOGs are:

HELLO 1,025
BOOT0 556
AUTOTRACE 470
BOOT1 468
RWTS 459
ADVANCED DEMUFFIN 1.5 439
ADVANCED DEMUFFIN 1.5 DOCS 439
PDP 399
SUPER DEMUFFIN 397
PDP.README 275
PDP DOCS 122
MENU 110
A 4AM CRACK (README) 105
TRACE2 94
TRACE 89
AUTOTRACE0 85
AUTOTRACE1 85
ADVANCED DEMUFFIN 1.1 85
IOB 66
CREDITS 53

However, the most common file names in the non-(4am crack) disk CATALOGs are:

HELLO 3,389
MENU 675
(7 x $08) 609
(empty) 525
LOGO 354
APPLESOFT 237
(6 x $08) 231
INTBASIC 191
TITLE 191
CHAIN 179
RUNTIME 134
START 127
MECC$$DISK 123
STARTUP 121
A 116
CAT 111
BOOT 107
FPBASIC 100
C 92
H 92

Which seems to confirm all the files like BOOT0, AUTOTRACE, BOOT1, RWTS, ADVANCED DEMUFFIN 1.5, ADVANCED DEMUFFIN 1.5 DOCS, PDP, SUPER DEMUFFIN, PDP.README, PDP DOCS, A 4AM CRACK (README), TRACE2, TRACE, AUTOTRACE0, AUTOTRACE1, ADVANCED DEMUFFIN 1.1, and possibly IOB and CREDITS are just artifacts of the cracking process.
