- I have to admit at first I expected most problems with PKZIP 2.04C
- to be DPMI related. Unfortunately that is not the case. Even in
- super safe mode (everything disabled, slowcopy etc) the program
- seems to make mistakes. An interesting example:
-
- I made a zip file of all cpp files included in Borland C++ 3.1 +AF
- examples directory (-r -p). I tried to extract bitma*.cpp. Strangely
- enough this fails with an CRC error but ONLY if there is already some
- bitmap.cpp in the current directory! If the current directory is not
- empty no error is produced. The test integrity option generates
- no problems.
-
- I am beginning to wonder how well tested this program is. And I
- wonder even more about what PKWARE did during all those delays. I
- am still impressed by the Super Fast compression. It is even
- super fast with 386 disabled.
