What is an ARQ file

ARQ files mostly belong to ARQ Backup. An ARQ file is not tied to one single purpose. Its role depends on the software that created it. Below are the main uses:

Backup Archive File: This version stores backup data. It is created by the ARQ Backup program to hold files for later recovery. For more details, visit ARQ Backup.

Brazilian Tax File: Some ARQ files use XML formatting to store tax information. They are used with tax-related applications like Tinus NF-e Manager to process electronic invoices.

Sony Alpha Raw Image: Other ARQ files serve as raw image containers. They incorporate TIFF elements and are used with photo editing software such as Adobe Photoshop Lightroom, capturing data from Sony Alpha cameras.

FilExt.com note: Each file should be opened with its matching tool. Check the file’s content or metadata to decide which application is needed.

ARQ format details:

If you can determine the file format, the associated program can also be determined. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. 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. Below is our analysis of the ARQ files:

ARQ is not that commonly used as a file extension. This file type is used by a few programs, each with its own file format. The two most popular formats are as follows:

• 25% of all ARQ files are ARQ archive files. They consist of unreadable binary data. The average file size is 2 MB with most files being between 48 KB and 15 MB in size. The file type was developed 20 years ago and is still in use today. A common filename is 20180601.ARQ. These files are attributed to backup.
• 15% of all ARQ files use the popular XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The average file size is 6 KB with most files being between 6 KB and 43 KB in size. The following keywords are characteristic: NFSE, <?xml version="1.0" encoding="UTF-8"?>, InfNfse id, <ConsultarNfseResposta xmlns="http://www.tinus.com.br"><ListaNfse><CompNfse><Nfse><InfNfse and Numero. Files like these are sometimes connected to consultar, nfse, olinda, jaboatao and mossoro.

All other ARQ files (60%) have no consistent format, the following 5 formats exist: TIFF and ZIP. Tagged as psms, activation or request. If you want to find out which format your ARQ file belongs to, just click on the button "Choose your .arq file to analyze".
