Examples

fcp.exe /cmd=update /include="*.json;*.xlsx" "d:\sourcedir\*.*" /to="\\remotePC\c\targetdir\"

fcp.exe /cmd=sync /log=FALSE /filelog="c:\FCP_YYYYMMDDHHNNSS.txt" "d:\sourcedir\*" /to="d:\targetdir"

Sandboxed multi-file copy
Copy a filtered subset of the samples folder (CSV/TSV/JSON/TXT/XML) into a UUID-named temp sandbox using fcp.exe (FastCopy's CLI binary). /cmd=diff copies only files whose size or mtime differs from the destination (default mode), /no_ui + /auto_close keep it headless, /log=FALSE skips the persistent log file. The Result panel lists every file FastCopy actually placed in the sandbox (name, size, modified) via a CF query; the Output panel shows FastCopy's own per-file/total summary. Both the copied files and the sandbox folder are removed on the way out, so this demo never leaves any state behind.
