A couple of months ago I went through my (Windows 7) PC and removed all versions (incl. all browser add-ins, etc.) of Adobe Flash from the system. After following the available uninstallation processes I manually deleted any "Adobe" and "Macromedia" folders.

I do not have any other Adobe products such as Acrobat or Illustrator installed on this machine.

Today I noticed that launching IE 11 causes an "Adobe" folder (with a subfolder structure "Flash Player\NativeCache") created in "C:\Users[my username]\AppData\Roaming\".

The folder (and it's subfolders) are created empty, which is maybe as expected if it is some kind of a caching folder.

I am assuming that it is added by some process related to IE because, if I delete the Adobe folder, it is not added back until when I launch IE. As far as my IE add-ons are concerned, they are all as shown in below image; no add-ons from Adobe are installed.

All IE add-ons

How can I determine what process keeps recreating this Adobe folder?

    Does this happen if IE is started in No-Addons mode? To open IE without loading Add-Ons, press WinKey + R, type iexplore -extoff and press ENTER. – w32sh Jul 29 '16 at 15:28

    It looks like adobe flash player did not uninstall completely. Follow this guide to make sure it is gone: helpx.adobe.com/flash-player/kb/… – Jack White Jul 29 '16 at 18:04
  • You should quote that article and submit an answer. – Ramhound Jul 29 '16 at 18:19
  • @w32sh, thanks I tried that and it launches IE with the "about:NoAdd-ons" URL and the message "Internet Explorer is currently running without add-ons". Still the folder is also created if it does not exist. – x457812 Jul 29 '16 at 18:58
  • @JackWhite, thanks for that tip, I will try the uninstaller and see if it resolves this issue. – x457812 Jul 29 '16 at 18:58

This is hard-coded inside IE's core module ieframe.dll. It creates the Adobe\Flash Player\NativeCache directory even in a clean (installed) system without Adobe Flash.

  • Thanks @w32sh, would you have a reference to this? – x457812 Jul 29 '16 at 19:46

    No reference though. But you can see the hard-coded string using Strings. strings "C:\Windows\System32\ieframe.dll" |findstr /i "nativecache" – w32sh Jul 29 '16 at 19:58

    Wow, what a kludge. Looks like w32sh is right – Jack White Jul 30 '16 at 0:02
