What is an ID file?

ID files mostly belong to Notes by HCL. An ID file contains user identification data used by Notes email client application. Another type of ID file contains information which Solidworks uses to verify the version of a download. ID is also the filename extension of an index file which MapInfo uses to verify the version of a download. SuperMap GIS 9D geographic information system saves its license in an ID file.

How to open ID files

Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ID file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ID file directly in the browser:.

ID format details:

The file format determines how the data is stored in the file. The file format can be deduced from the file extension and the signature. File extension, signature and file format must match; otherwise errors will occur when the file is opened. If there are problems opening a file, you must first determine the file format used. Our examination of the ID files comes to the following conclusion:

The ID extension is quite commonly used. The file itself is used by a few programs, each with its own file format. However, the following two file formats are common:

55% of all ID files use the same file format, which have the signature 01 00. These are binary files, so they do not contain words or text. Most of these files are 5 KB to 8 KB in size. The file type was developed 10 years ago and is still in use today. An example of a file name is user.id.
4% of all ID files start with the bytes SOLIDWORKS 20 crucial for this file format. The content consists of readable text data, which can be read using a text editor. ID files can be up to 40 bytes in size, but are often around 20 bytes - 30 bytes. Several words can almost always be found in the files, e.g. SOLIDWORKS and Edition. Examples of file names are swdata1.id or swdata99.id.

All other ID files (41%) have different formats, frequently e.g. InterActual Disc, GZIP, GIF, XML and Solid. Often described as machine, disc, insight, cert, jtaxrbbwua, secure, data or gene. If you want to find out which format your ID file belongs to, just click on the button "Choose your .id file to analyze".
