Delete all Characters up to a certain Character from File Names

That is possible with the File Renamer, for example with regular expressions:

In the Search and Replace function:

Search for:   .*?\-(.*)
Replace with: $1

And don't forget to tick the box next to "Interpret  as regular expression".

Important: Since the minus sign - is a character with special meaning within regular expressions, we write \- to escape the character. If this is not the case, for example if we want to delete everything up to an x, the following is sufficient: .*?x(.*)
