FastCopy is the Fastest Copy/Delete Software on Windows.
It can copy/delete unicode and over MAX_PATH(260byte) pathname files.

Automatically, after whether the copy origin and copy destinations are HDD according to same physical HDD or is judged, it operates as follows:
Diff HDD: Reading and writing are done with the MultiThreading in parallel.
Same HDD: Using big buffer, reading until the buffer becomes full, and writing in bulk.

Because Read/Write doesn't use the cache of OS at all, other processes (application) do not become heavy easily.
Read/Write performance is a near the limit of the device. Include/Exclude Filter (UNIX Wildcard style) can be specified.
