SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Moving large volumes of files between disks, servers, or network storage is slow and error-prone with basic copy commands, and failed transfers often require starting over. This Skill configures FastCopy to run parallel, resumable, verified transfers driven by reusable YAML profiles. ## Core Features & Use Cases - Parallel Stream Transfers: Copy files with up to 64 concurrent streams, configurable buffer sizes, and bandwidth limits. - Profile-Based Automation: Define sources, destinations, filters, schedules, hooks, and notifications in YAML profiles for recurring backups and sync jobs. - Integrity Verification & Resume: Validate transfers with SHA-256 or CRC-32 checksums and resume interrupted copies with configurable retry logic. - Use Case: A sysadmin needs to migrate terabytes of media files to new storage overnight. They create a turbo-mode profile with 64 streams, include filters for video formats, and a completion hook that sends a notification when the verified migration finishes. ## Quick Start Ask the AI to create a FastCopy YAML profile that copies a source folder to a backup destination with 32 streams and integrity verification enabled.

Frequently Asked Questions about fastcopy-file-transfer-utility

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I copy large files faster with parallel streams?▼

Use FastCopy with the --streams flag to run up to 64 concurrent transfer streams, for example fastcopy /source /dest --streams 32. Higher stream counts suit local SSD transfers, while 16-32 streams work better for network copies.

How to automate recurring file backups with YAML profiles?▼

Create a YAML profile defining transfer mode, source and destination paths, filters, and a cron schedule, then run fastcopy --profile backup.yaml. Profiles support hooks for pre and post transfer scripts plus email notifications on completion or error.

Does FastCopy verify file integrity during transfers?▼

FastCopy supports integrity verification using SHA-256 or CRC-32 checksums enabled with the --verify flag or verify: true in a profile. You can force re-verification with --verify --force or skip checks with --no-verify for speed.

Can FastCopy resume an interrupted file transfer?▼

FastCopy resumes interrupted transfers using the --resume flag or resume: always in a profile, combined with configurable retry counts and backoff intervals. This is recommended for unreliable network connections.

Why is my FastCopy transfer slow over the network?▼

Slow network transfers usually result from too few streams, small buffers, or bandwidth saturation. Increase streams to 32-48, raise buffer_size_mb, enable prefetch, and set bandwidth_limit_mbps to prevent congestion.
