Hi guys

 I have a table in a access db it has several fields, but i am only interested in 2.

the first field is uniquekey, this represents the db uniquekey of each track
ie: 3402
     5601
     6507


the second field is filename

which is basically the full path to where the track is stored,
i.e. Filename  D:\Tracks\fff250bd-6c12-4f11-ab9e-a84568a74afb\1cd6e11e-b89e-4899-9aea-31f01401b18c.mp3

I need to copy and rename the files to another folder from all the rows in the table renaming the mp3 files to the uniquekey.

the database name is library
the table is csv

 Could anybody please give me some code to achieve this in vb.net

Best regards

Jimbo
