What is a PER file?

PER files mostly belong to Various. PER files are used to store a range of data types. They do not follow a single standard but are named by the application that created them.

• Climate Data: Some PER files hold climate research data produced by groups like the Climatic Research Unit. These files store measurements and trends that support climate analysis. You can learn more on the CRU TS Data Page.
• Flight Simulation: Other PER files contain aircraft performance data for simulation programs (for example, X-Plane). They often use zlib compression to pack numerical data for flight planning.
• Event Reporting: Certain PER files record events or performance metrics in industrial settings, such as power plant event recordings or performance event reports.
• Software Licensing: A few PER files serve as license files for products like JMP, storing activation or registration details.
• Game Data: Some are used in games, storing AI parameters, game rules, or replay data for titles like Age of Empires II and even configuration data for car paint or sports replays.

FilExt.com notes: Each PER file must be opened with the appropriate software. In many cases, if the file shows XML data or compressed content, a text editor may reveal its structure. Always check the file source to decide which application is needed.

How to open PER files

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

PER file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. If there are problems opening a file, you must first determine the file format used. Our analysis of the PER files produces the following result:

The PER file extension covers different formats for different programs. The following file formats are most commonly found in PER files:

• 25% of all PER files use the same file format, which have the signature Climatic Research Unit . If you open these files in a text editor, you can view and read the content yourself. A typical file size is 17 KB. This file type is new and state-of-the-art. The keywords Units, parameter, Climatic Research Unit Country File created on Thu 16 Apr 2020 15:57:18 BST, from CRU TS run #2004151855, Precipitation, month and Temperature are typical for these files. Such PER files store data about crucy, india, ethiopia, mozambique, actaeon, canada, group, italy and music.
• 10% of all PER files use the popular zlib file format. Zlib is a compressed archive file format that supports several different data compression algorithms. zlib is also a crucial component of many software platforms, including Linux, macOS, and iOS. These files are binary files, so they do not contain text, but only cryptic characters. PER files can be up to 1 MB in size, but are often around 24 KB - 950 KB. The file name 777-200LR GE90-110-115_v1.00.per or Q400_v1.00.per is characteristic of these files. These files are often associated with genx.

The remaining 65% of all PER files are files with no common format, the following 9 formats can be found: Source, ZIP, NOT, Platform, PER and Date. Tagged as reser, space, recording, acpursuit, constants, airbus, sample or rules. Just click the "Choose your .per file to analyze" button on this page to find out what your PER file is.
