description: Data Extract and File Transfer activities now recognize replacement tokens in filename patterns regardless of letter case. Whether you use %%Year%%, %%year%%, or %%YEAR%%, the token resolves correctly instead of appearing as literal text in the filename. This change brings Data Extract and File Transfer in line with Import and Export activities, which already support case-insensitive tokens, and prevents file generation and matching errors.

# Prevent Filename Errors with Case-Insensitive Date and Time Tokens in Automation Studio

Data Extract and File Transfer activities now recognize replacement tokens in filename patterns regardless of letter case. Whether you use %%Year%%, %%year%%, or %%YEAR%%, the token resolves correctly instead of appearing as literal text in the filename. This change brings Data Extract and File Transfer in line with Import and Export activities, which already support case-insensitive tokens, and prevents file generation and matching errors.

**Where:** These changes apply to Marketing Cloud Engagement Corporate and Enterprise editions.
