# PREPARE THE FILES

If you downloaded handwriting samples from the CSAFE Handwriting Database, the samples are ready to go, so click Next. Otherwise, keep reading.

## Save the Images as PNG

Save the handwriting samples as PNG images.

## Rename the Files

Rename each image file to include the writer ID and the document name in each file name.

Example file names from the CSAFE Handwriting Database: "w0001_s01_pLND_r01.png", "w0001_s01_pLND_r02.png", "w0002_s01_pLND_r01.png", "w0002_s01_pLND_r02.png".

The writer IDs need to be the same number of characters and in the same location in each file name. They can contain letters and numbers. For example, the CSAFE Handwriting Database writer IDs are "w0001", "w0002", and so on.

The document names also need to be the same number of characters and in the same location in each file name. For example, the CSAFE Handwriting Database uses document names like "s01_pLND_r01" to refer to the session number, prompt code, and repetition number.
