What is a 201 file

201 files mostly belong to WinZip. *.201 files are compressed archive files that use the ZIP format.
These files usually store data in a compressed container, making them smaller and easier to transfer. They may be used as a part of multi-volume archives or versioned backups.

They use the ZIP standard to package content.

They are often created by backup or archiving software.

You can open them with software like WinZip or WinRAR.

If you have a *.201 file, check that it is not one part of a series of files before extracting. You can find more details at WinZip.
FilExt.com tip: Proper extraction is key when dealing with split archives.
Files with the extension 201 are often also jpg images or pdf documents, but zip compressed archives or medical images such as DICOM are also common. Use the Online 201 File Viewer on this page to find out the file format being used, and to view your 201 file.

How do you open 201 files?

201 file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the 201 files is as follows:
