User guide

System requirements

• Windows: Windows 10 or 11, 64-bit (x64).
• Linux: a 64-bit (x86-64) desktop distribution with a graphical session (X11 or Wayland), for example Ubuntu 22.04 or newer, Debian 12, Fedora.
• About 250 MB of free disk space.
• An internet connection once, to start the trial (and at least every 14 days with a subscription).

Install on Windows

1. Download YFastCopy-Setup-windows-x64.exe from this website.
2. Optional: check the file. In PowerShell run Get-FileHash .\YFastCopy-Setup-windows-x64.exe and compare the result with the SHA-256 shown on the home page.
3. Open the file. If Windows SmartScreen shows “Windows protected your PC”, choose More info and then Run anyway.
4. Follow the installer. YFastCopy is installed for your user account; no administrator rights are needed.

To uninstall, use Settings → Apps → Installed apps → YFastCopy → Uninstall. Your settings and queue stay in %APPDATA%\YFastCopy until you delete that folder.

Install on Linux

1. Download YFastCopy-linux-x64.tar.gz.
2. Optional: check it with sha256sum YFastCopy-linux-x64.tar.gz.
3. Unpack and install:
   tar xzf YFastCopy-linux-x64.tar.gz
cd YFastCopy-linux-x64 && sudo ./install.sh
4. Start YFastCopy from your applications menu.

To uninstall, run sudo /opt/YFastCopy/uninstall.sh.

First start and the free trial

On the first start YFastCopy connects to the internet once and starts your 7-day trial. The Subscription section in the sidebar shows how many days are left. All features are available during the trial; no payment details are needed.

The trial belongs to the computer: it is not restarted by reinstalling. When it ends, copying and moving are locked until you subscribe.

Copy and move files

1. Under Source choose Add files, Add folder or Add drive. You can also type or paste a path.
2. Under Destination choose Choose folder.
3. Click Fast copy to copy, or Fast move to move (the originals are removed only after a successful copy). You confirm a move before it starts.

The progress card shows speed, amount transferred, elapsed and remaining time. The activity log lists every step; Save report writes it to a text file.

Speed modes and SHA-256

Choose the mode in the top bar:

The SHA-256 switch verifies each file after it is written in any mode. Verification reads the data again, so it takes a little longer, but you know that the copy is identical to the original.

The transfer queue

• Everything you add goes into the Transfer queue. Start queue runs the waiting items one after another.
• Pause after file stops after the current file; Resume continues.
• Cancel after file stops safely; a partly copied file is never left looking complete.
• Requeue selected puts failed or cancelled items back in the queue; Remove selected deletes them from the list.
• Compare checks source and destination by name and size (without reading the contents).
• The queue is saved. After a restart it is restored, but nothing starts on its own.

Copying a whole drive

Choose Add drive and select a drive. YFastCopy queues its folders and files and skips system items such as the recycle bin and system volume information. A drive is never copied onto itself or into one of its own folders. If you copy the system drive, files that you are not allowed to read are reported and skipped.

Subscription

Open Subscription in the sidebar:

• Monthly — €2.99 or Yearly — €31.99: opens the secure Stripe payment page in your browser. After payment, YFastCopy activates by itself within a few seconds. The page also shows your license key; the receipt is sent by email.
• Enter license key: use your subscription on another computer (up to 3 in total).
• Manage subscription: change the plan, update the card, download invoices or cancel (Stripe customer portal).
• Remove from this computer: frees a place, for example before you replace a computer.
• Check again: asks the server for the current state right away.

Final prices, no extra costs. A cancelled subscription stays active until the end of the period you paid for. If a renewal payment fails, YFastCopy keeps working for 3 days while the payment is retried.

Languages and appearance

Pick the language with the globe button in the top bar. Choose a colour theme with the coloured dots, and in the sidebar under Appearance switch between light and night mode, a background image, card shadows, a compact sidebar, alert sounds and window opacity. Every change is saved immediately. Autostart starts YFastCopy when you sign in.

Troubleshooting

• “Connect to the internet once to start your free 7-day trial.” The app could not reach the license server. Check the connection (or proxy/firewall) and choose Subscription → Check again.
• “This key is already used on 3 computers.” Choose Remove from this computer on a computer you no longer use, then enter the key again.
• “Destination exists; no silent overwrite.” A file with the same name is already in the destination. Choose another folder or remove the old file first.
• The subscription is paid but not shown. Choose Check again. If it still does not appear, write to us with the email used for payment.
• Report a problem: click Save report in the activity log and send the file to sadollahkarami1@gmail.com.
