How i have to specify my file selection using wildcards?
* means any 0 to n signs of any character
? means exactly 1 character
E.g:
t*?.txt could select test.txt telefon.txt but not t.txt .
* selects every file
*e?ef*.t* could select telefon.txt and elefant.text
??.? selects every file, which consist of exactly 2 characters before
the dot and one character after.
... be creative.
