• Introduction
◊  Verifile is a small utility that calculates a checksum and a CRC32 on both the data and resource forks of any file that's dropped on it. This is useful if you want to compare two files that are not on the same machine without having to copy them over a network or modem connection. If the hexadecimal numbers displayed by Verifile match, chances are that the two files are equal.

• Version history
◊  1.2.4 - Now freeware, updated documentation and recompiled with CodeWarrior 9.
◊  1.2.3 - Won’t ask if an untitled document should be created when a stationery pad is dropped on Verifile.
◊  1.2.2 - Optimized PowerPC code, cooler online docs.
◊  1.2.1 - Cleaned up the code and updated documentation.
◊  1.2 - Fat version! Runs native on Power Macs, displays elapsed time to measure processor and disk performance. The PowerPC code runs a lot faster than the 68K code if the file to verify is on a RAM disk, while the speed improvement is smaller on slower media.
◊  1.1 - Rebuilt with new versions of the compiler (never released).
◊  1.01 - Fixed a small bug that prevented Verifile from opening data files under System 6 (Apple's New Inside Macintosh recommends using HOpenDF instead of HOpen, but it doesn't say it only works under System 7). Thanks to Howard L. Dyckman for reporting this problem.
◊  1.0 - First final release.
