FastCopy is the Fastest Copy/Delete Software on Windows. It can copy/delete Unicode and over MAX_PATH(260-byte) pathname files. Automatically, after determining whether the copy origin and copy destinations are HDDs according to the same physical HDD, it operates as follows. Diff HDD: Reading and writing are done with MultiThreading in parallel. Same HDD: Using a big buffer, reading until the buffer becomes full, and writing in bulk.

Because Read/Write doesn’t use the cache of the OS at all, other processes (applications) do not become heavy easily. Read/Write performance is near the limit of the device. Include/Exclude Filter (UNIX Wildcard style) can be specified. It operates lightly because MFC is not used, and it makes use only of the Win32 API.
- FastCopy is the Fastest Copy/Backup Software on Windows
- It supports UNICODE and over MAX_PATH (260 characters) file pathnames.
- Because it uses multi-threads for Read/Write/Verify, Overlapped I/O, and Direct I/O, it brings out the best speed of devices.
- It supports an Include/Exclude filter like a UNIX wildcard.
- It runs fast and does not hog resources, because MFC is not used. (Designed using Win32 API and C Runtime only)
