What is a PDAT file?

PDAT files mostly belong to Archive Manager. PDAT files serve two main purposes. The most common use is as a device log archive that uses ZIP compression to store and bundle device logs. These files collect operational records from devices such as the ResMed AirSense 10, allowing technicians or users to extract and review performance data efficiently.
Some files with the PDAT extension use the PNG format to hold image data. In these cases the file is considered a Portable Data File and may be opened in programs like Adobe Photoshop.

If your PDAT file is a log archive, simply renaming the extension to .zip and opening it with an archive manager will let you view the individual logs.

If the file contains image data, use an image viewer or editor that supports PNG.

FilExt.com tip: Always keep a backup of the original file before trying any conversions.

Programs that open and convert PDAT files:

Archive Manager
See the previous paragraphs to learn more about the main application. PDAT files are often referred to as Archive Manager compresseds because this type of file is primarily created or used by this software.
ResMed AirSense 10; Adobe Photoshop
A .PDAT file is primarily a zipped archive, encompassing detailed operational logs generated by certain medical devices, notably the ResMed AirSense 10. These files encapsulate comprehensive data regarding device usage, settings, and performance, serving as a crucial resource for diagnostics and treatment optimization. While less prevalent, .PDAT can also denote a Portable Data File, often containing image data in the PNG format. This usage is generally associated with image processing software like Adobe Photoshop. This file format is classified as Data File.

PDAT file format:

Every file has a defined file format, i.e. how the data is arranged in 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. 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. So you need a detailed analysis of a file to find out the format and the associated program. Our examination of the PDAT files comes to the following conclusion:

The file type with the extension 'PDAT' is primarily used by a single program. The two most popular formats are as follows:

90% of all PDAT files internally use the ZIP format, multiple files are compressed and combined into one PDAT file. A typical number of included files is 104. Customary file names are \mnt\, \mnt\flash\, \mnt\flash\conf\config_notifications.ini, \mnt\flash\conf\config_operatingtime.ini, \mnt\flash\conf\device.xml, \mnt\flash\data\, \mnt\flash\data\debug\connman.log, \mnt\flash\data\debug\develop.log, \mnt\flash\data\debug\develop1.log, \mnt\flash\data\debug\dosfsck.txt, \mnt\flash\data\debug\kern.log, \mnt\flash\data\debug\kern.log.0, \mnt\flash\data\debug\kern.log.1, \mnt\flash\data\debug\service.log, \mnt\flash\data\debug\therapy-sw.log, \mnt\flash\data\debug\therapy-sw1.log, \mnt\flash\data\maintenance\mc_calibr.bin and \mnt\flash\data\maintenance\service.log. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. The file size is in the range of 1 MB to 10 MB. Certain words are almost always found in the files, such as mnt/flash/data/maintenance/service.log and mc_calibr. The following filename is common: therapy.pdat.
2% of all PDAT files store the data in the PNG file format. PNG is short for Portable Network Graphics. It is a high-quality raster image file that supports lossless data compression. They consist of illegible, cryptic characters. The files are often between 420 bytes and 140 KB in size. Certain words are almost always found in the files, such as IHDR and Adobe. Files like these are sometimes connected to shell.

All other PDAT files (8%) have no uniform format. Sometimes used for data, party, leader, prpd or prps. Just click the "Choose your .pdat file to analyze" button on this page to find out what your PDAT file is.
