What is the .SUM File Extension?


.SUM File Extension Description:

The file extension SUM is used as a generic summary file of reports by third party applications, and also as a file report for data integrity checks done through a checksum protocol.

As a summary file, the file extension .sum is used similarly as a .log file, wherein the text-based data that the supporting application generates are dumped into one of these files for archiving. The files extension .sum is not used for any program operation sequence, but only as a user reference for application actions. The .sum files in this form pose no risk to software stability should it be deleted from the file medium.

Another program that makes use of the .sum format is the checksum procedure for files in the operating system. The process of subjecting a file to checksum lessens the instance of acquiring a corrupted file while passing from one media to another. The process by which the .sum file is generated after checksum assures the user that the each data encoded with the received file has the same structure as that of the source.

The algorithm used in a .sum file is a repeated check of data file structures, from the moment of file decryption, expansion, and data packet sending over through space. The data retrieved from the .sum file of a sent file supposedly should have the same bit-location and validated value as that of the original file. Any deviation from this within the .sum file usually results in a newly created duplicate file that is erroneous and non-readable.

The file extension .sum is one of the many file summary formats used in the integrity transmission of files over a network. Other formats with different algorithms include the Cyclic Redundancy Check (CRC) and the Hash formats.
