Hi Stef,
Assuming I understand what you're trying to do:
This is broken out to hopefully make it clear what the steps are:
| src srcPrefix dstPrefix dst |
src := 'a/b/c/d.pi' asFileReference.
srcPrefix := 'a' asFileReference.
dstPrefix := 'result' asFileReference.
dst := dstPrefix resolve: (src relativeTo: srcPrefix).
dst
At that point presumably you want:
src copyTo: dst.
Cheers,
Alistair
