What is a XER file

XER files mostly belong to Primavera P6. XER files are Primavera P6 project files that store project scheduling data. They include details about tasks, durations, dependencies, and resource assignments.
These files are used primarily with Oracle's Primavera P6 software to exchange and archive project data. You can view the file as a text document, but a proper display of the scheduling structure requires Primavera P6 or a compatible conversion tool.

File type: Project schedule file

Usage: Scheduling, planning, and project data exchange

Tool: Oracle Primavera P6

How can I open a XER file?

You need a suitable software like Primavera P6 to open a XER 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 XER file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a XER file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert XER files:

Primavera P6
See the previous paragraphs to learn more about the main application. XER files are often referred to as Primavera P6 data files because this type of file is primarily created or used by this software.
Primavera Project Management (Propriety Exchange Format) by Primavera Systems, Inc
In Primavera’s Project Management module, you can exchange project data with other Primavera users by converting projects to Primavera’s Proprietary Exchange Format ( .XER ). Using Primavera’s import/export capability, you can then convert a XER file to an SDEF data file, and vice versa. The identifying characters used for this association are - Hex: 45 52 4D 48 44 52 09, ASCII: ERMHDR .

XER format details:

Each file has a definite file format, that is, how the stored data is arranged in 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. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the XER files is as follows:

XER is not that commonly used as a file extension. This file type mainly uses a defined XER format. The file formats most commonly found in XER files are:

95% of all XER files are Primavera's proprietary exchange format files. If you open these files in a text editor, you can view and read the content yourself. The files are 44 KB to 6 MB in size, with a median of 940 KB. The file type was developed only in the last few years. The files contain the following words: ERMHDR, dbxDatabaseNoName, Project, CURRTYPE, Project Management, curr_id, curr_symbol, decimal_digit_cnt, decimal_symbol, digit_group_symbol, pos_curr_fmt_type and admin. Such files are related to schedule, baseline, programme, project, updated, update, construction, building, initial, revised, draft and work.

The remaining 5% of all XER files are different files with different signatures. Sometimes used for sample. Drag & drop your file here to see the file format and a preview of your XER file!

How to solve problems with XER files

Associate the XER file extension with the correct application.
Update your software that should actually open project schedule files. Because only the current version supports the latest XER file format. Search, therefore, e.g. on the manufacturer website after an available Primavera P6 update.
To make sure that your XER file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
