What is a FOL file?

FOL files mostly belong to QuickBooks. Some FOL files are zipped FL7 files used to store FastReports layout data. They work with QuickBooks and use ZIP compression to keep the layout information secure. More details can be found at the QuickBooks website.

Zipped FL7 File: Contains compressed report layout data. It is used within QuickBooks for FastReports layouts and typically needs a ZIP extractor or the native QuickBooks tool to open.

Gerbil Database File: Acts as a database file in the GERBILDB3 system. This format holds structured data and requires specialized database software to view or modify.

How can I open a FOL file?

You need a suitable software like QuickBooks to open a FOL 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 FOL file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FOL file directly in the browser:.

FOL file format:

To find out what program is needed to open FOL files, you need to determine the file format. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. 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. Knowledge is power - this also applies when dealing with unknown or faulty files. Below is our analysis of the FOL files:

As a file extension, FOL isn't very common and does not have a uniform file format. The two most popular formats are as follows:

6% of all FOL files use ZIP compression, multiple files are compressed and combined into one FOL file. Such a ZIP file contains 3 to 22 files. Customary file names are 1.FL7. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. The files are 4 KB to 120 KB in size, with a median of 15 KB. A usual file name is 20180601.FOL.
4% of all FOL files start with the bytes 08 00, which are crucial for this file format. These files contain neither text nor words, but only data. FOL files can be up to 510 KB in size, but are often around 17 KB - 290 KB. The keywords GERBILDB3 are typical for these files. Files like these are about hosp.

All other FOL files (90%) have no consistent format, frequently e.g. GERBILDB. Sometimes used for bapt. If you want to find out what your FOL file contains, drag and drop it onto this page.
