Automatically generates checksums for each file and directories using the SHA 1, SHA 2 (256) or MD5 algorithms.However, it doesn’t validate formats or metadata documentary. Extracts other interesting information from the files like their sizes, dates of last modification, locations, among others.The format identification is also linked to PRONOM, an online database that contains technical information of file formats, software and technical environments.
To do this, it uses internal signatures (magic number: alphanumeric characters that identify a file) and, when they exist, the external ones (file extension).
Can accurately identify specific file formats (more than 1400) even when the file extension is wrong or non-existent.It can be used from a graphical user interface or though the command line.Desktop application written in Java (requires version 1.7 or higher).This process provides the verification of the format that usually announces the file extension and checks the degree of matching with the corresponding structure, which is especially useful at the time of intake. Format analysis applications allow the identification and validation of a certain format.
