Solved I keep losing free space on C: drive.

November 7, 2019 at 18:03:03
Specs: Windows 8.1
(8.1 OS) Adobe Premier Elements is writing 2 empty files on C: every day when I power on my desktop. Over the past 4 months alone this has resulted in 8.5 GB of wasted space just for the file names. Adobe Corp. is useless for help as to why this happens. The file names are ".cfa" and ".pek" under \AppData\Roaming\Adobe\Common\Media Cache Files\60001.MTS48000_xxx.* (where xxx=numbers starting from Jan.19/19 with "1" to today with "689" - although there are some files created in 2018 as well). I haven't used this program in the last 4 months. Does anyone know the purpose of these files? Can I safely delete them? Or move them to my DATA drive? Can I stop them from being created - or cause them to be created on the DATA drive? I'm running seriously low on space on C: Would appreciate any assistance. Thanks. UPDATE: dug a bit deeper - the .pek files are all about 3,038 KB while the .cfa files are 0 bytes.

I am astonished that you haven't deleted those junk files long ago.
8.5 GB of empty files is a huge amount. I don't know what their
purpose is or why they are being created every day, even when
you aren't using the program that creates them, but they clearly
aren't needed. You can safely delete all of them.

One thing you could try to stop them from being created is to look
in Task Scheduler for entries that refer to Adobe Premier Elements.
Task Scheduler has a fairly large number of entries (but not a huge
number), so you may have to spend some time looking. If you find
something for Adobe Premier Elements, disable or delete it. When
you next run the program, though, that entry will undoubtably be
re-created, so that isn't a permanent solution.

Look in Adobe Premier Elements for a setting having to do with
watching for new files, or changes, or startup. Most likely the files
have something to do with that. Turn that function off.

✔ Best Answer
A very quick search turned this up in the first hit on "cfa file":

Adobe Conformed Audio File

Developer Adobe Systems

Category Audio Files
Format Binary

.CFA File Association 2

A CFA file is a cached audio file created by several Adobe software
programs, including After Effects, Premiere Pro, and Encore. It contains
audio data that has been conformed to a proprietary Adobe format.
CFA files are used for improving the software's performance when
processing audio data and when generating audio waveform previews.

When importing audio data, the software transforms the audio into a
format that can be quickly processed by the software. This removes the
need for the audio to be reprocessed each time it is used. However, due
to the caching, there may be a delay the first time audio is imported.

CFA files may become very large in size. You can turn off the caching
option within Adobe applications, but the processing time for audio
previews may increase.

CFA files are actually created by Adobe Media Encoder, a standalone
software component that is included with programs such as Adobe After
Effects, Premiere Pro, and Encore. All such programs reference the
same audio cache.

End quote.

Thanks Jeff. That's good info. I also found out that .pek files are created alongside .cfa files and are also audio metadata files created by Adobe apps. They can be deleted and the software will regenerate them unless the option to turn off caching is set in the app. My Premiere Elements program is fairly old and doesn't have the option to turn off caching. However, I discovered that long ago I altered this program to store all files on my F: (Data) drive instead of C: but somehow I missed the Media Cache setting. So now I have the .pek and .cfa files routed to F: and then I deleted all the old ones from C: Now I have 42 GB of free space on C: and no new pek/cfa files were created on C: on power-up today. So - problem solved - I think. Thanks for your help.
