I have opened Activity Monitor from /Applications/Utilities to monitor  
the ATSServer process to get further information.
I have done this for the system administrator (Administrator) and for  
the user MyName, selecting the process "ATSServer" and looking at  
further information (opened files and ports).

This is the result for Administrator:
---------------------------
/
/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ 
Frameworks/ATS.framework/Versions/A/Support/ATSServer
/private/var/folders/kp/kpPJ1mt.../-Caches-/com.apple.ATS/annex_aux
/System/Library/Fonts/LucidaGrande.dfont
/System/Library/Fonts/HelveticaNeue.dfont
/System/Library/Fonts/Helvetica.dfont
/System/Library/Fonts/Monaco.dfont
/usr/lib/dyld
/private/var/db/dyld/dyld_shared_cache_i386
/dev/null


/private/var/folders/kp/kpPJ1mt.../-Caches-/com.apple.ATS/font
/private/var/folders/kp/kpPJ1mt.../-Caches-/com.apple.ATS/annex_aux
->0x7e13330
---------------------------



And this is the result for the user MyName:
---------------------------
/
/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ 
Frameworks/ATS.framework/Versions/A/Support/ATSServer
/Users/MyName/Library/Caches/TemporaryItems/ATS - 227034826/annex_aux
/System/Library/Fonts/LucidaGrande.dfont
/System/Library/Fonts/HelveticaNeue.dfont
/System/Library/Fonts/Helvetica.dfont
/System/Library/Fonts/Monaco.dfont
/usr/lib/dyld
/private/var/db/dyld/dyld_shared_cache_i386
/dev/null


/Users/MyName/Library/Caches/TemporaryItems/ATS - 227034826/font
/Users/MyName/Library/Caches/TemporaryItems/ATS - 227034826/annex_aux
->0x5aefcc0
---------------------------


What irritates me, is the fact, that Administrator uses the path / 
private/var/folders/kp/kpPJ1mt.../-Caches-/com.apple.ATS/ and user  
MyName uses the path /Users/MyName/Library/Caches/TemporaryItems/ATS -  
227034826/ to store the font caches.

Why arent they using the same path?
Why does the folder /Users/MyName/Library/Caches/TemporaryItems/  
exist, but not for Administrator (/Users/Administrator/Library/Caches/ 
TemporaryItems/)?
Why is Administrator using the path under /private/var/folders/kp/ 
kpPJ1mt.../-Caches-/com.apple.ATS/ and not the path /Users/ 
Administrator/Library/Caches/TemporaryItems?
Or, asked vice versa for user MyName: why is user MyName *not* using  
the path /private/var/folders/kp/kpPJ1mt.../-Caches-/com.apple.ATS/  
but instead the path /Users/MyName/Library/Caches/TemporaryItems?


It looks like, that the trashed folders and files in the "Recovered  
files" folder, when logged in as user 'MyName'  are from /Users/MyName/ 
Library/Caches/TemporaryItems/ . But why?
Any hints to solve the problem?
