What is a 221 file?
221 files mostly belong to Taxprep. *.221 files serve two distinct roles.
One role is as a Canadian tax return data file. These files are used with tax software such as Taxprep and are connected to systems like CCH ProSystem fx and ProFile Tax Software. They store structured financial data for filing taxes.
The other role is as a comic book archive that uses the ZIP internal format. In this case, the file compresses a series of images for comic archives. These archives are managed with utilities like 7-Zip (7-Zip) and can also relate to techniques found in RAR compression.
Examine the file header to know which type it is. If the file belongs to tax software, open it with Taxprep or related programs. If it is a compressed archive, use extraction tools like 7-Zip.

- Readable XML/JSON suggests structured application data.
