Double File Scanner 2.04 This tool allows for detecting duplicate files on your hard-drive quickly, based on SHA-1 hashes. 1. Introduction ------------------------------------------------------------------------------ The purpose of this tool is scanning the selected directory or directories for duplicate files, i.e. files with identical content. Duplicate files are identified by first calculating the SHA-1 digest of each file and then looking for values that appear more than once. In particular, files with identical content are guaranteed to have the same SHA-1 digest, while files with differing content will have different SHA-1 values with very high certainty. All computed SHA-1 values are stored in a hash table, so collisions are found quickly and we do NOT need to compare every digest to every other one. Also, the files are processed concurrently in multiple "worker" threads in order to parallelize and speed-up the SHA-1 computations on multi-core processors. On our test machine it took ~15 minutes to analyse all the ~260,000 files on the system drive (~63.5 GB). During this operation ~44,000 duplicates were found. Once the scan is completed, the program provides commands to review, rename or delete the duplicate files manually. Alternatively, the "automatic clean-up" wizard may be invoked in order to remove ALL redundant files at a single blow. Optionally, the list of duplicates can be exported to the XML or INI format. ------------------------------------------------------------------------------ 2. Platform Support ------------------------------------------------------------------------------ The following platforms are supported: - Windows 8 and 8.1, 32-Bit and 64-Bit versions - Windows 7, 32-Bit and 64-Bit versions - Windows XP, Service Pack 3 is required! Platforms that should work too, but are not tested extensively: - Windows Vista, 32-Bit and 64-Bit versions - Windows XP Professional x64 Edition, Service Pack 2 is required! ------------------------------------------------------------------------------ 3. Anti-Virus Warning ------------------------------------------------------------------------------ Anti-Virus programs can interfere with the Double File Scanner software and significantly slow down the process! Therefore it is highly recommend to turn off the "real time scanner" or "guard" feature of your Anti-Virus program while the Double File Scanner is running. But don't forget to re-enable it! ------------------------------------------------------------------------------ 4. Command-Line Options ------------------------------------------------------------------------------ The following command-line options are available: --console Enable the debug console --scan <directory> Scan the specified directory, can be used multiple times List of influential environment variables: DBLSCAN_THREADS Set the number of worker threads (default: auto detect)
