The 2012 file extension is a year-based suffix used for various data files. Because it is not tied to one application, files with this suffix may have different internal formats and purposes.
A 2012 file may contain backup, financial, tax preparation, business, calendar, schedule, or accounting data. The software that created the file is required to determine how its contents are structured and used.
If the file name contains two extensions, the original extension may appear before .2012. In that situation, the 2012 suffix may have been added to identify the creation year rather than to indicate a new file format.
A 2012 file cannot be opened reliably by choosing a program based on the suffix alone. Identify the application or service that created the file, then open it with that software.
If the file has two extensions and .2012 was appended to an otherwise familiar name, make a copy and remove the final 2012 suffix from the copy before trying the original application. Do not change the extension of the only copy.
There is no general converter for the 2012 file extension, because it can represent different underlying data formats. Conversion depends on the application that created the file.
Open the file in its original software, if possible, and use that program's export or Save As function to create a supported format. If the original application cannot be identified, reliable conversion may not be possible.
