What is a DAY file?

DAY files mostly belong to Novitus Mała Kasa. An DAY file can hold data recorded on a daily basis. In one use, these files serve as fiscal records that store Polish receipt data; they are produced by vendors such as Novitus Mała Kasa. In other cases, the same extension is used for database records. For example, some DAY files use the JetDB internal format to keep gas database information, a setup seen in systems like Standard Jet DB and AspenTech InfoPlus.21 (more details). There are also DAY files that hold station data for hydrological measurements (GRDC-Data-Processing-Tool - details), while some come in a compressed form using ZIP (as seen with Axelerator).
FilExt.com tip: If you need to open your DAY file, check which tool or vendor created it. For fiscal data, the vendor’s application is used; for database or hydrological records, a matching database or processing tool is required; and if the file is compressed, a standard decompression application should work.

How to open DAY files

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