The file synchronization program supports file filters and several different ways of comparing and synchronizing files. There are also general statistics about the total number of files and folders that would be created if the user would synchronize the files. Statistics for each column are displayed in the footer listing the number of directories, files and the size of the data conveniently. overwrite file in the left column, copy file to the right column) are taken if the Synchronize button is pressed. Arrows in the middle indicate the action (e.g. Information about each file including its name, size and modification date are displayed in the table as well. A click on the Compare button at the top will generate a directory and file listing for every directory that has been added to the application.Īll files and directories are displayed in both columns with a blank row in the opposite column if the file or directory does not exist there. The two main actions offered by Free File Sync are to compare or synchronize the directories and the files residing in them. The main interface is separated into a left and right column. Invisible data corruption can occur.Free File Sync is an Open Source file synchronization software that's above everything else super-easy to use. It is not enough merely to check the filenames on the destination drive agree with those on the source drive. This doubles the time to transfer files, but the complete file data comparison check gives confidence of success. You need to click the blue cogwheel next to Compare and select File Content from the menu. In addition, I use FreeFileSync to copy files over USB3 links and then I perform a "byte-by-byte" comparison of files on the source and destination drives. You do not want Windows to power down your USB devices to save energy, especially during long file transfers. Open each and every instance of USB Root Hub or Generic Root Hub and disable Windows Power Management. If any of your external drive cables are more than 30cm (1ft) long, buy new shorter cables.Īnother thing you can do on a Windows PC is dive into Device Manager (in Control Panel). I use 30cm Startech USB3 cables with a Kingston CF/SD/microSD card reader on my laptop to reduce data corruption. Low quality portable USB3 hard disk disk caddies come with thin spindly 0.5m (1.5ft) leads which should be consigned to the garbage bin. Most high quality USB-C portable SSDs come with very short cables, typically 20cm (8in) long. This is because you have reduced or entirely removed undesirable cable effects from the equation.Īlthough you cannot do much about the USB3 cable inside the computer up to the front panel, you can shorten portable HDD/SSD cables to the absolute minimum. In theory you can transmit USB3 over much longer cables, but in practice, shorter = better.Īs you've discovered, connecting your USB3 devices to the rear panel usually results in success. This doesn't affect low speed USB2 waveforms to anywhere near the same extent as much faster USB3 waveforms. If you add another 30 to 50cm (1 to 1.5ft) of external cable to a portable hard disk or SSD, you've doubled the crosstalk and further degraded the digital waveforms with even more cable capacitance.Ī point comes where the relatively "clean" square waves of the USB3 digital signal at the mptherboard are reduced to "sine" waves at the end of 60 to 100cm (2 to 3ft) of wire. It's probably down to long cables with the associated increase in crosstalk between adjacent (unscreened) wires.Ī typical computer case has over 30cm (1ft) of cableform between the motherboard and the front panel USB ports.
