Files - Checksum Calculators (8)

muCommander is a Java-based skinnable, tabbed file manager with a dual-pane interface. The tool connects to a many online services such as FTP, SFTP, SMB, HTTP, Amazon S3, Bonjour, HDFS (Hadoop), NFS and more. File copying includes transfer verification, rate of speed controls and transfer visualization. It can open and create a variety of archive types as well as view and modify ZIP files without recompression. The program can batch rename, change permissions/date and hash files or folders with a variety of algorithms.

Cross-platform (Mac, Linux, *BSD) and available in 27 languages.

Alternatively, X-muCommander is also available.

7-Zip is an archive manager that can view and create a wide variety of formats. The program includes folder favorites, optional two-pane view, checksum calculator, file split/combine capability and more. Individual archives can be created with high speed or high compression settings, update options (including update, add/replace, synchronize), split volumes and more. Archives can be secured with standard zip or more secure AES encryption.

Although the official archiver for the open, high-compression "7z" format, the program also supports the creation of multiple formats including ZIP, XZ, BZIP2, GZIP, TAR and WIM. It will extract a long list of other formats, among them RAR, CAB, ISO, ARJ, RPM, VHD, VMDK etc. Even more formats are supported through third-party plugins. Supports many world languages.

Additionally, to use alternative toolbar and file icons, 7-Zip Theme Manager is available.

7-Zip Portable is a wrapper from PortableApps.com, auto-detecting 32 or 64-bit automatically. Alternatively, X-7zip is also available.

There is also a 7-Zip standalone console version.

FreeCommander XE is a powerful, dual-pane file manager with hundreds of features including folder size calculation, folder comparison/synchronization, file/duplicate search, filtering, MD5 calc / verfiy, folder compare, sync and a customizable interface. Includes a file viewer to view files in hex, binary, text or image format; an archive handling ability for standard compressed formats including ZIP (read, write), CAB (read, write) and RAR (read); built-in copy/move/delete handlers; and much more. Additional features are available via plugins.

A 64-bit version is available for donors, while a PortableApps version is also available from the author's website.

SFV Ninja allows you to check the integrity of any number of files. After running on a file list, the program can then check all files on that list, with the option to only verify/update only newly added files. The program can recursively scan/generate a folder for files and load them all at once, using relative paths whenever possible.

Useful to quickly checking system files or archives for modification/corruption. Supports many commonly-used hashing algorithms listed here from fast/simple to slow/secure: SFV (CRC32), MD5, SHA-1, and SHA-256.

PeaExtractor is a easy, minimalistic tool for unpacking almost any compressed file format. Features a search tool, progress bar and drag-and-drop functionality. The program can unpack over 180 formats including encrypted or multi-volume archives (usually a series like .000, .001 or .r01, .z01...) as well as standard formats like 7z, rar, tar, zip, zipx, bzip2, cab, iso etc.

The program aims to function as a simple, accessible alternative to file manager-like interfaces used by WinRAR, WinZip and 7-Zip. Cross-platform (Linux, BSD) and developed by the author of PeaZip.

NOTE: Open ACE files with additional steps. The download also includes pea.exe, containing other tools including checksums, secure delete, file lists and more.

SigcheckGUI is a system and security analysis tool for understanding files and processes. The program shows a variety of file data including signing source, 32/64-bit status, version, publisher, and more. Security options include VirusTotal analysis and file hashing (MD5, SHA1, and SHA256). The program can even run on all active processes.

The program can export results to spreadsheet (CSV) or copied to the clipboard.

SigcheckGUI is a front-end for Sigcheck from Sysinternals.

FileVerifier++ checks and compares files to see if they have been modified. Supports drag-and-drop, recursive directory processing, patterns, color coding, export to a variety of hashing formats (.sfv, .md5, .csv, etc.) and more. Can use any of 21 different hashing algorithms such as CRC16 for speed and SHA-512 for security (uses the standard MD5 by default).

The program (ZIP version) will automatically ask to create verification files with relative pathways, which is much more portable.

Win2K users should use an earlier version. A beta 64-bit version is available.
