An AEE file is a temporary cache file that Adobe applications create while you work

An AEE file is a working copy that Adobe software — most commonly Adobe Acrobat, Adobe Reader, or other Adobe Creative Suite programs — saves to your hard drive while you have a document open. It holds the current state of your work so the program can recover it if something goes wrong, like a crash or unexpected shutdown.

The file sits in a temporary folder on your computer, usually with a name like "~AEE1234.tmp" or similar. You will not normally see it unless you go looking in your system's temporary files, because Adobe hides it by default and deletes it when you close the document properly.

These files are not dangerous, and they do not contain anything you have not already saved. They are simply a safety net — a way for Adobe to say "if the program crashes right now, I can restore what you were working on."

Key Takeaways

  • AEE files are temporary working copies created by Adobe applications while documents are open.
  • They are stored in your system's temporary folder and deleted automatically when you close the document normally.
  • Finding an AEE file on your computer usually means an Adobe program did not close properly the last time you used it.
  • You can safely delete AEE files without affecting your saved documents or the programs themselves.

Why Adobe creates AEE files in the first place

When you open a PDF or other document in Adobe Reader or Acrobat, the program does not work directly on your original file. Instead, it creates a temporary copy — the AEE file — and works on that. This protects your original document from being corrupted if something interrupts the program.

If the program crashes, loses power, or freezes, the AEE file stays on disk. The next time you open Adobe, it can offer to recover your work from that temporary file. Without it, any unsaved changes would be lost completely.

This is the same reason other programs create temporary files: Word creates .tmp files, Chrome creates cache files, and so on. It is a standard safety practice across software.

When you will see an AEE file on your computer

You will usually find AEE files only if you go looking in your temporary folder. On Windows, that folder is typically C:\Users\[YourUsername]\AppData\Local\Temp. On Mac, it is ~/Library/Caches or a similar location depending on which Adobe app created it.

The most common reason you will notice an AEE file is if Adobe did not shut down cleanly. Maybe the program froze and you force-quit it, or your computer lost power while Adobe was running. In those cases, the temporary file remains behind because the program never got the chance to delete it.

You might also see AEE files if you are cleaning up your temporary folder manually, or if a system maintenance tool flags them as old files taking up space.

How to safely delete AEE files

AEE files are safe to delete at any time. They are temporary files, not part of your actual documents or the Adobe installation. Deleting them will not affect your saved PDFs, your Adobe software, or any other programs on your computer.

The simplest approach is to let Windows or macOS clean them up automatically. Both operating systems have built-in tools that remove old temporary files periodically. On Windows, you can also use the Disk Cleanup utility: open Settings, search for "Disk Cleanup", select your drive, check the "Temporary files" box, and click Delete.

If you want to delete them manually, navigate to your temporary folder, find files with names starting with "~AEE" or containing "AEE", and delete them. Make sure no Adobe programs are currently running before you do this, so the files are not in use.

What happens if you leave AEE files alone

Leaving AEE files on your computer causes no harm. They take up very little space — usually a few kilobytes to a few megabytes each — and they do not slow down your system or interfere with anything else running.

The only minor downside is that they accumulate over time if Adobe crashes repeatedly or does not shut down cleanly. If you have dozens of old AEE files from months ago, they are just clutter. Deleting them frees up a small amount of disk space and keeps your temporary folder cleaner.

If you want to prevent AEE files from piling up, the real solution is to make sure Adobe closes properly. Save your work, use File > Exit or Command+Q to close the program, and wait for it to finish shutting down before you restart your computer or turn it off.

AEE files versus other Adobe temporary files

Adobe creates several types of temporary files, and AEE is just one of them. You might also see files with names like "~ACV", "~ACE", or other Adobe-specific prefixes. All of them work the same way: they are working copies that Adobe deletes when the program closes normally.

If you see a large number of different Adobe temporary files accumulating, it usually means one of your Adobe applications is crashing or not closing properly. In that case, consider restarting your computer, updating Adobe to the latest version, or reinstalling the program if the crashes continue.

Frequently Asked Questions

Is an AEE file a virus or malware?

No. AEE files are created by legitimate Adobe software and contain only temporary working data. They are not a security risk. If you are concerned about malware, run a scan with your antivirus software, but AEE files themselves are harmless.

Can I recover a document from an AEE file if I did not save it?

Possibly. If Adobe crashed and left an AEE file behind, the next time you open Adobe it may offer to recover your work. However, if you manually deleted the AEE file or if your computer lost power, recovery becomes much harder. Always save your work regularly to avoid this situation.

Why does my computer keep creating new AEE files?

If you see new AEE files appearing frequently, it usually means Adobe is crashing or not closing properly. Try updating Adobe to the latest version, restarting your computer, or reinstalling the program. If the problem continues, check Adobe's support site for known issues with your version.

Do I need to do anything with AEE files, or can I ignore them?

You can safely ignore them. They will be deleted automatically when Adobe closes properly, and they take up minimal space. You only need to think about them if you are actively cleaning up your temporary folder or if they are accumulating because Adobe keeps crashing.
