What is a DAT file?
Many different programs use the .dat file extension. When you see a file on your computer with the .dat extension, all it really means is that the file contains some type of computer data. There is really no way to tell what type of data the file contains unless you open it. The problem is, unless you know where the file originated from, the data contained within the .dat file be hard to decipher.
They DAT file format is, in fact, one of the most common file formats in existence. It is very often used to save attachments that have been sent from an Outlook email client.
