filechecksums

This application uses JDK's build-in algorithms to compute a file's checksums, such as CRC32, MD5, SHA, ect. It's quite useful to make sure your download is correct, especially on large files. Steps: Click "File" button to select a file on your hard drive. Select checsum(s) ... [More] you want to compute. Click "Go" button to start the computing. It may take a while for computing on a large file, so be patient, or you can click "Cancel" button to interrupt the task. [Less]

liten2

Why use this tool?It's FAST. and reliable. We accomplish incredible speeds by not including logic in our indexing engine. The first part of the program performs a scan in a selected path and stores the meta-data in a database. To improve speed even further, the database is created and worked on ... [More] while in memory. Interactive solutionThe interactive approach in Liten2 allows you to work on deleting files right after a search or at a later date. You are in control of what to delete after the indexing is done. Liten2 will search a given directory and find duplicate files building a report at the end. Uses a SQLite DB to store searches and optimize file handling after it has run. SHA-224 is used as a checksum method, this will provide for a better and more precise way of handling differences in files. We have updated the bytes Liten2 reads to create the checksum from 8 kilobytes to 16. This will make Liten2 create a better checksum. Currently working on GNU/Linux and Mac OS Operating Systems only. SetupThis was developed with python 2.6 and has not been tested with earlier versions of Python. No installation is currently necessary, just uncompress the TAR file and run the file with Python. DependenciesLiten2 depends on SQLite3. This will not be a problem in a normal Python install. However, it will not work with earlier versions of Python because we are using functionality found in Python2.6 Download and Uncompresstar xzvf Liten2-*.tar.gz First Time RunFor the first time run you need to supply a path to search with the "-p" flag: python liten2.py -p /path/to/directoryThis will output a SQL file where the reports will generated from in a Date format like: YEAR-MONTH-DAY.sql Duplicate ReportOnce Liten2 has run there is no need to run it again to re-read the reports: python liten2.py -rThis will re-read the SQL file that was dumped in the previous run. NOTE: Liten2 will only look for the SQL file with today's date, as for now, you can't tell liten2 to choose from a different SQL file. Interactive Delete SessionLiten2 has an interactive session (you need to have run liten2.py before) that will group identical files together and will let you choose the files to delete: python liten2.py -iWhen interactive mode, you can hit Ctrl-C to quit (nothing will be deleted). The group of identical files will be numbered and you will be asked to type a number to delete or hit Enter to skip to the next group. Dry RunA Dry Run option is available only when running the interactive mode. Nothing will be deleted when this option is used. Identical files will be shown and your selections will be saved. At the end of the session a message will display that nothing was deleted. To use this option: python liten2.py -i -dChoose File Size to SearchBy default, Liten2 will search for files over 1 megabyte in size. You can specify a larger size (always in megabytes) to search with the "-s" flag: python liten2.py -s 5 -p /path/to/directoryThe command above will search for files over 5 megabytes in size in the given directory path.

vgmtoolbox

VGMToolbox is a emulated music file auditor inspired by Roman's clrMAME Pro and Cowering's GoodTools. Without these two, it would likely never exist. It currently parses all files matching the PSF spec in a manner that prevents duplicates. It will ignore tag data and internal compression. ... [More] It rebuilds based on the "real" data contained in the files. Also included are a couple of file examination utilities. The first is an MDX file parser that will scan for PDX libs needed and whether they exist in the right folder. This tool will also display the title information and PDXs needed in a nice tree structure. The second tool is a PSF format explorer. Simply drag and drop file(s) or folder(s) onto the directory text box and it will parse all of the files' tag data and display them in a nice tree. This can help identify needed library files or let one just look at the tags. Unfortunately, for now, both tools only read in the top level of each folder, subfolders are not yet handled. More tools will be added, and these ones will be completed. I have not yet added docs, but it should be pretty self explanatory. For collectors, choose your source and destination folders and rebuild. After your rebuild, have and miss text files, a fixdat (if needed) and a cache.db file will be created. The have/miss and fixdat files should be understandable. The cache.db is simply a zlib compressed, serialized c# array of crc32 values of your matching sets. This helps generate the have/miss files and allows you to archive your existing sets if you are low on hard drive space. You can remove rebuilt source and overwrite existing sets (for tag updates or whatever reason). For datafile makers, things are pretty much the same as clrMAME Pro. The main differences include always being in subfolder mode, and lack of MD5/SHA1 support. Files in the top most directory are ignored and only subfolders and ALL of their contents (including their subfolders) are checked. While MD5/SHA1 support is implemented, it requires using file streaming for generating these checksums. For now I have commented out this portion of code and will add it as a checkbox with proper warning labels later. Thanks much to manakoAT for helping me test the application. He found many things that slipped through the cracks. Notes: -- Zip files are not yet supported for either source or destination -- It is highly advised to choose the 'Use less RAM' option on both the Datafile Creator and Rebuilder. Although a bit slower because of file streaming, it is more throughly tested and will preserve RAM usage. Due to the way .NET memory is handled, objects over 85k are put in a separate heap. This heap is NEVER compressed and eventually Out of Memory errors will occur because the heap space becomes too fragmented. Currently, a byte array pool is used when the 'Use less RAM' option is not selected. While this prevents the out of memory errors, the pools will hold memory until the program is shutdown. The byte array size is also not sufficient for at least one 2SF set. More testing will be performed to obtain a proper byte array size (if I do not remove the option all together). -- Datafiles containing PSF spec data will not be usable in any existing rom auditors. Since no existing auditors parse the data how I do, nothing will ever match (except by chance). The checksums for non-PSF spec files will be the same as other rom auditors (cmpro and romcenter), though size data is not generated due to being invalid for PSF files. As I will in some way distribute my algorithm, perhaps in the future other auditors can use it. -- The datafiles produced are using v1.2 of Logiqx generic datafile. It will be updated to v1.3 soon. -- As this is an alpha, you must only work with backed up data. Although source files are all opened with Read Only permissions, you never know what can happen.

jmd5sum

Important notice:This project has been renamed to JDigest. This site is obsolete and will no longer be updated. Please kindly check http://code.google.com/p/jdigest/ for the latest version. Description:JMD5Sum is a graphical file MD5 sum calculator and verifier, written in Java for cross-platform ... [More] portability. When installed in Windows, it will create the Windows Explorer associations so that you can calculate checksums by right clicking files or folders, and verify checksums by double-clicking md5 files. Other platform users will have to use the command line (run java -jar jmd5sum.jar to get the command line help). I hope I can find some free time to add an automatic installer for Linux. Requirements:JRE 6 Current features:Two modes of operation: calculates the checksum of the given files and directories (recursively) into a md5 file, and matches file checksums against a md5 file Progress indicators: size, speed and ETA, for both current file and total Windows Explorer integration (If installed using the windows installer package) Current issues:md5 files are written and read in UTF-16. This was made so in order to correctly store file names using a different codepage than the system locale. However, it makes generated md5 files incompatible with other md5 software (like command line md5sum). A workaround is to convert the md5 files (in windows this can be done by opening the file in notepad, selecting "Save as" and choosing either ANSI or Unicode). I plan to add an encoding setting in the future. The source code is plain ugly. I used to be a good coder, but it's surprising how rusty you can get when you don't code often. Suggestions are welcome. Future features:md5 file encoding settings Installer or similar for the different flavors of Linux [Less]
