TeraCopy is a free utility designed to copy files faster and more secure. It automatically switches between synchronous and asynchronous modes to improve the speed of file transfers. File verification TeraCopy can test files after copy to ensure they are identical. This is done by comparing hashes of source and target files. Error recovery In a case of a copy error, TeraCopy will try to recover and, in the worse case scenario, will simply skip the file, not terminating the entire transfer. Create and verify checksum files All popular formats are supported, including MD5, SHA, RIPEMD, Tiger, Whirpool and xxHash. Interactive file list TeraCopy shows the failed file transfers and lets you fix the problem and recopy only the problem files. You can also remove unnecessary files or folders to reduce the transfer time. Informative progress bar A speed graph inside the progress bar visually indicates problematic and skipped files using different colors. Shell integration TeraCopy can completely replace the Explorer copy and move functions, enabling you to work with files as usual. You can also quickly set as target any folder open in Explorer.
