Opening FID Files

The FID file type is primarily associated with FileMaker Pro.

What is a FID file?

FID files mostly belong to FileMaker Pro. A FID file is not a single standard file type. Instead, it is used in different fields to store structured data. Depending on its origin, a FID file can hold iOS framework data, image data, or scientific data.
Main uses:

iOS Data File: Some FID files are flattened data files used within the iOS framework. They are often associated with FileMaker Pro, which manages app data. Refer to the FileMaker Pro website for more details.

Image File: Other FID files use JPG encoding internally. In this case, they may come from processes involving Fujifilm and be handled in software like Adobe Photoshop.

NMR Spectroscopy Data: Another type of FID file holds raw spectroscopy data. In nuclear magnetic resonance (NMR) experiments, FID stands for free induction decay and represents the initial time-domain signal. These files can be used with applications such as Mnova NMR software or TopSpin (see also the Mnova webpage).

Usage note:
FilExt.com tip: Examine the file’s internal structure or metadata to decide the correct program for opening it. Some files may also employ ZIP compression for layered data storage.

How to open a FID file

You need a suitable software like FileMaker Pro to open a FID file. 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 FID file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FID file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert FID files:

FileMaker Pro
See the previous paragraphs to learn more about the main application. FID files are often referred to as FileMaker Pro data files because this type of file is primarily created or used by this software.
Bruker Aspect NMR Data File
File Investigator by RobWare
Computer forensics software for criminal investigators and consumers. The identifying characters used for this association are - Hex: 46 69 6C 65 20 49 6E 76 65 73 74 69 67 61 74 6F 72 20, ASCII: File.Investigator.
Microsoft Index Server (Database file) by Microsoft
FID files are catalogs files of Microsoft Index Server, stored in the content index catalog directory C:\System Volume Information\catalog.wci. A catalog is the highest-level unit of organization in Microsoft Index Server. Each catalog is a completely self-contained unit, containing an index and cached properties for one or more scopes (virtual roots). This file format is classified as Database.

FID format details:

A file format defines how the data in the file is structured. The file format can be determined based on the file extension and the signature (the first few characters of a file). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the FID files is as follows:

The FID extension is quite commonly used. The file itself includes many different file formats. However, the following two file formats are common:

4% of all FID files start with the magic bytes Ïúíþ, which are always the first bytes of this file format. If you open these files in a text editor, you will see only illegible characters. A typical file size is 4 MB. The keywords __TEXT, __PAGEZERO and __stubs are typical for these files.
1% of all FID files belong to NUTS format. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are on average 260 KB in size and range from 66 KB to 260 KB.

The remaining 95% of all FID files are different files with different signatures. If you want to find out what your FID file contains, drag and drop it onto this page.

How to solve problems with FID files

Associate the FID file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest FID file format. Search, therefore, e.g. on the manufacturer website after an available FileMaker Pro update.
To make sure that your FID file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
