PWI file format details:

To view or edit PWI files you need to know the file format, because it determines how the data in this file is stored. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the PWI files comes to the following conclusion:

PWI is a very commonly used file extension and is primarily used by a single program. However, the following two file formats are common:

• 90% of all PWI files belong to Pocket Word document. These files contain neither text nor words, but only data. A typical file size is 2 KB. This file type was primarily in use more than 10 years ago. Certain words are almost always found in the files, such as {\pwi and Tahoma. Such PWI files store data about note, morning, worship, books, notes, numbers, info and song.
• 3% of all PWI files have the same signature 01 00 00 00. These files contain text and words as well as binary data. PWI files are between 430 bytes and 2 KB in size. The files contain the following words: Message Column Width, ShowGrid, Source Column Width, Version, Address Column Width, Time Column Width and AutoResize. The file name Simulation.PWI is characteristic of these files.

All other PWI files (7%) have no uniform format, frequently e.g. DOC. Files like these are sometimes linked to account, meeting, bank, cari, lunes, find, name or trip.
