fastcopy-file-transfer-accelerator

Run fastcopy.exe followed by the source path, destination path, and options such as /cmd=diff or /cmd=sync. Add /verify for integrity checks, /bufsize=256 for buffer tuning, and /log with /logfile to record results.

Diff mode copies only new or changed files while keeping extra files at the destination, making it suitable for incremental backups. Sync mode mirrors the source exactly, deleting destination files that no longer exist in the source.

Use 32-64MB for small file sets, 128-256MB for medium transfers up to 10GB, and 512-1024MB for very large files like videos or databases. For network transfers over SMB, 256-512MB generally works best.

Yes, FastCopy supports UNC paths like \\Server\Share directly, and you can map a drive with net use if UNC fails. Use /force_close and a moderate buffer size for reliable network transfers.

Access denied errors occur when files are locked by other processes or permissions are insufficient. Run with elevated privileges, add /force_close to close open handles, and include /acl when copying permission-sensitive data.

Create a scheduled task with Register-ScheduledTask in PowerShell that runs FastCopy.exe with arguments like /cmd=sync /verify /log /force_close. Trigger it daily and check the log file and exit code to confirm success.
