File Extension ATT

.ATT File

File extension: ATT
File type: (POSTDATA.ATT)

Notes about the ATT file extension:

To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The ATT file type is primarily associated with 'Web Form Data'. If the file is named POSTDATA.ATT then most likely the file contains the results from a Web form. This will be an ASCII text file with a bunch of strange characters betwee the data fields. You can open the file in any text editor and read past all the junk or use a tool such as Post Data Spider to just show the data. You should also be able to use the Import Wizard in Excel to bring the data fields into an Excel worksheet. The format is similar to a .CSV file so adding a .CSV extension to the end of the file's name should also allow you to open the file in a number of other programs that accept CSV-formatted data files.
