The issue of cached files is a challenge for many users of 3DEXPERIENCE.

To address this, @DM has documented the processes below by which these files can be removed. 

Here are the steps to remove cached files at two separate locations:

Cached Files 1

The first cache is where the files from the 3DEXPERIENCE Launcher reside. While these files do not typically generate errors when using 3DEXPERIENCE, they can become quite large. As these files are most typically located on the same drive as the Windows installation, they can cause some very significant IT issues. The cached files are located in

C:\\ProgramData\\DassaultSystemes\\3DEXPERIENCELauncher\\defaultDataStore

To clear these files, you should

1. Ensure that 3DEXPERIENCE is closed.
2. Open Windows Explorer and navigate to C:\\ProgramData\\DassaultSystemes\\3DEXPERIENCELauncher\\defaultDataStore
3. Delete the Cafs and Media folders (see below).

Cached Files 2

The other cached files can cause a number of severe errors when using 3DEXPERIENCE. These can include errors associated with CAD and simulation apps as well as issues saving and importing data. 

To clear this cache:

1. Ensure that 3DEXPERIENCE is closed.
2. Open Windows Explorer and navigate to C:\\Users\\username\\AppData\\Local\\DassaultSystemes
3. Delete all the folders in this location (see below).

Also note, the AppData folder may be hidden. To make it visible, click on the View tab of Windows Explorer and toggle on Hidden Items (see below).

Please let us know in comments if you face any issues while performing the above steps.
