SNU file extension format:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the SNU files:

The SNU file extension is not common and predominantly uses a uniform format. The file formats most commonly found in SNU files are:

70% of all SNU files have the same signature 03 00 00. They consist of unreadable binary data. The files are often between 100 KB and 3 MB in size.

Such SNU files store data about music, ssfx, brute, dementia, awakens, attack, charge, hunter, audio and roar.
9% of all SNU files have the same signature 01 0C 00 00. They consist of illegible, cryptic characters. The average file size is 35 KB with most files being between 22 KB and 310 KB in size. The files contain the following words: D____________. An example of a file name is d_as01_xxx_0003bb5.exa.snu. Files like these are sometimes connected to xxxx.
