Daz studio file structure (CLOSED) (CLOSED)

Pinspotter's intervention in the thread
https://www.renderhub.com/forum/6556/too-many-programs-or-just-set-up-wrong
made me take a closer look at Daz's files. I think that there are indeed files which pollute our hard drives and which can be deleted.
But which files can we really delete without crying a few days later?
In summary, is there technical documentation that explains the structure of folders and indicates the role of parameter files for example. I know of a few that contain the menu structure 
C:UsersusernameAppDataRoamingDAZ 3DStudio4toolbars.dsx
The latest renderings
C:UsersusernameAppDataRoamingDAZ 3DStudio4temprender
C:UsersusernameAppDataRoamingDAZ 3DStudio4tempRenderAlbumTmp
But can we delete the files from the
 C:UsersusernameAppDataRoamingDAZ 3Ddsoncachedata
 folder without regretting it the next time we restart?

I had forgotten that the Slatch character had been removed

The latest renderings
C: - Users - username - AppData - Roaming - DAZ 3D - Studio4 - temp - render
C: - Users - username - AppData - Roaming - DAZ 3D - Studio4 - temp - RenderAlbumTmp

Files to save to restore our favorite interface
C: - Users - username - AppData - Roaming - DAZ 3D - Studio4
actions.dsx
anonymousGuid.dat
cloudLog.txt
ContentDirectoryManager.dsx
customactions.dsx
dazstudio.dau
dzloadplugins.dsx
dzrendersettingsdimensionspresets.dsx
layout.dse
layout.dsx
log.txt
menus.dsx
RecentFiles.txt
RenderDirectoryManager.dsx

optional files I'm sure
cloudLog.txt
log.txt
RecentFiles.txt

But can we delete the files from the
C: - Users - username - AppData - Roaming - DAZ 3D - dson - cache - data
 folder without regretting it the next time we restart?

Hah, I had just replied on the other thread wondering the same thing about the dson-cache-data folder.

If you delete the cache, it might take a bit longer next time you load figures, because it will re-cache them.
