~~**%\_file\_create\_date%** gives you DD.MM.YYYY not DD/MM/YYYY~~

**$regexp(%\_file\_create\_date%,(..)/(..)/(....),$3$2$1)** gives you YYYYMMDD like you want it.

Edit:  
How to write it into a tag:  
Action: Format Value  
Field: YEAR  
Format String: $regexp(%\_file\_create\_date%,(..)/(..)/(....),$3$2$1)
