Extract text from email attachments (ATT00001)

To convert other file formats to the "Unrecognized Email Attachment" file type, you need software like Microsoft Outlook or a similar tool.
The .att00001 file is a generic placeholder created by email clients when they fail to properly decode an incoming message. This almost always happens when emails are sent from Microsoft Exchange Server or Microsoft Outlook using proprietary Rich Text Format (RTF), or when sending images via the SMIL multimedia standard. When receiving clients like Apple Mail, Gmail, or older mobile apps cannot understand the proprietary Microsoft formatting, they separate the unrecognized data and dump it into an attachment named ATT00001.
Depending on what the sender originally included, this file could be a hidden JPG, PNG, or GIF image. In many cases, it is simply a plain text read receipt, a delivery status notification, or leftover HTML formatting code. The main disadvantage of an .att00001 file is that your operating system has no idea what to do with it. Because it lacks a recognizable file extension, double-clicking it usually results in an error. It is a completely useless and frustrating format until you can identify its true internal structure.
Because the file is disguised, you first need to identify its actual contents. If it is an image, convert to JPG or PNG for web use and sharing. If it is a text receipt, convert to TXT or PDF for archiving. We will detect the true format and fix it for you instantly.
