I think I found a solution in 3 steps:

**1.)** Split your existing path into a temporary tag field, like MY\_SPLITTED\_FOLDERPATH with an  
Action Type "Format value"  
Field:  
`MY_SPLITTED_FOLDERPATH`  
Format string:  
`$replace(%_FOLDERPATH%,'\','\\')`

this would look like this if you press ALT + T:

**2.)** Get the needed item from the newly created MY\_SPLITTED\_FOLDERPATH tag into the ARTIST tag with a second action:  
Action Type "Format value"  
Field:  
`ARTIST`  
Format string:  
`$meta(MY_SPLITTED_FOLDERPATH,3)`

The number after the comma indicates the item number. In our example  
`C:` would be item number 0  
`Temp` would be item number 1  
`mp3-Test` would be item number 2  
`author` would be item number 3  
`book` would be item number 4

**3.)** Clean up all the no more used MY\_SPLITTED\_FOLDERPATH tag fields with an action  
Action Type "Remove fields"  
Fields to remove:  
`MY_SPLITTED_FOLDERPATH`
