Veretino

Be confident in the integrity of your data.

With this application, the integrity of both individual files and entire lists can be verified. Analyze the contents of folders, calculate checksums, and easily find modified or corrupted data...

The app allows you to check the folder-wide data integrity, for example, after numerous transfers and recopies, uploads/downloads from clouds and storages, transfer to other devices, and so on...

Key features:

• Multiple checksums calculator and organizer.
• Validation of the copied/moved/long-stored folder.
• Checking the integrity of file arrays.
• Verification of folder immutability.
• Data audit: analysis of folder contents, looking for folder-wide data changes.
• Finding damaged files in a folder.
• Creation and verification of Digest files.
• Comparing files by checksum.

Veretino can check the integrity of a large amount of data, for example, after a disk or file system error occurs, bad or unreadable sectors appear, a sudden power outage and similar cases...

How it works:

• To begin with, the program calculates a list of checksums for all files (or filtered file types) in the specified folder (and its subfolders) and stores it in the local json file (see Veretino Database format).
• Having a ready-made database, the program becomes able to check the integrity of the folder's data by reading its current contents and comparing it with the previously created data set.
• The resulting data also makes it possible to find new or missing items by comparing the current contents with a previously one.

The program allows analyzing the contents of folders by file types, their number and size. Finding the largest and most numerous file types, which is useful when creating a database with a specific filter.

When working with individual files: the program can operate with checksums (copy, store, check) both from the clipboard and digests (*.sha1/256/512).

The App allows you to avoid unexpected data loss*, for example, in case of a disk error or incomplete download. Checking across the entire folder and multiple subfolders allows you to detect data loss in any of the contained files.

*Please note that the Veretino app does not repair the data and is not able to prevent its loss, but only serves to verify its integrity.
