Unlike other media file formats like MP3, WAV, MP4, etc., files in this format can't be opened with just any multimedia player. EPM may instead refer to Encryption Policy Manager, which is an encryption client program used with Check Point security software for encrypting portable removable media storage devices like flash drives, CDs, and DVDs, etc. EPM is also an acronym for Oracle Enterprise Performance Management and the unit of concentration called equivalents per million, but neither has anything to do with the EPM file format. How to Open an EPM File EPM files are encrypted media files, meaning that you'll need to use a certain program to play the video or audio file you might have. Unfortunately, we don't have any information on how to do this. Some EPM files may be containers for other files, similar to the ZIP format. If that's what your file is, you should be able to extract its contents using a file unzip tool like 7-Zip. For example, if you're using 7-Zip, just right-click or tap and hold the EPM file, and then pick the option that says 7-Zip > Open archive. You'll then be able to see the contents stored inside and copy out the files you want, or extract everything out at once. Endpoint Media Encryption Software Blade opens files associated with Check Point's Encryption Policy Manager. If you find that an application on your PC does try to open the file but it's the wrong application or you'd rather have another installed program open it, you can change which program opens EPM files by default in Windows. How to Convert an EPM File If you manage to get an MP3 from the EPM file, you can use a free audio converter to convert it to some other audio format like WAV. The same is true for encrypted videos that are stored as EPM files—a free video converter can convert MP4s and other similar formats. Still Can't Open the File? If you still can't open your file, you might be misreading the file extension. Some files have a similar file extension even though they don't open with the same program. Some examples of this include EMP, EAP, PEM, EPS, EPC, RPM, CEP, EPRT, and EPUB files.
