Opening an ENP File

The ENP file type is primarily associated with ENVI.

ENP	File extension: ENP
	File type:	data file

What is an ENP file?

ENP files mostly belong to ENVI. ENP files can represent different types of data depending on their origin.
For instance, one common use is as an ENVI Raster Metadata file. This version stores metadata related to remote sensing imagery, including details linked to a spectral library.

ENVI Raster Metadata: Contains sensor calibration, geospatial positioning, and spectral data; used with ENVI image processing software.

Another type is the e-NP data file, employed in engineering procurement systems to hold project or purchasing information.

e-NP Data File: Manages structured data in an engineering or procurement context.

A third variant is an encrypted file with metadata, which includes secure data along with its encryption details. Tools like EncryptOnClick or AxCrypt handle this type.

Encrypted File with Metadata: Secures content by embedding encryption parameters; access requires the proper decryption tool and key.

FilExt.com tip: If you have a ENP file, identifying its origin is key to opening it correctly. Use ENVI software for the raster metadata; consult your procurement system for data files; and use the matching decryption tool for encrypted variants.

How can I open an ENP file?

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

ENP file format:

If you know the file format, you can also find out how to open or edit the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our analysis of the ENP files produces the following result:

The ENP file extension is rather rarely used and is used by a few programs, each with its own file format. The two most common formats are as follows:

• 30% of all ENP files use the same file format, which have the signature IVPF. These are binary files, so they do not contain words or text. The files are on average 39 MB in size and range from 160 KB to 280 MB. This file type is based on cutting-edge technology. Certain words are almost always found in the files, such as <?xml version="1.0" encoding="UTF-8" standalone="no" ?>, <DATASET>, <HEADER>, <HEADER_VERSION_MAJOR>1</HEADER_VERSION_MAJOR>, <HEADER_VERSION_MINOR>1</HEADER_VERSION_MINOR> and IVPF. The file name n27e083_to_n28e085_arc_v3_2.tif.enp is typical for these files. These files are often associated with mosaic and tiff.
• 30% of all ENP files start with the magic bytes A0 96 06 08, which are always the first bytes of this file format. These files are binary files, so they do not contain text, but only cryptic characters. The files are often between 540 bytes and 27 KB in size. A usual file name is e-NP_Updates20180601.enp or e-NP_Permits20180601.enp. These files are attributed to permits, request, updates, reponse and master.

The remaining 40% of all ENP files are different files with different signatures. These files are often connected to xlsx, report, ecler, list, shareholder, monthly, signed or demo.
