File sender adapter (FTP) regular expressions

Hi everybody,

I Need to pick files with this format: "ABC_12345678.xml". (exactly 8 digits)

I'm trying to achieve this requirement with "File Name Mask" in the file adapter.

Regular expressions like "ABC_[0-9]{8}.dat" or "ABC_\d{8}.dat" seems not to work.

Does File adapter supports regular expressions? STFP is not available in my PI.

Currently i'm using "ABC_*.xml" in order to pick the files but i need to restrict more than that because files like 'ABC_ABC.xml' fix the pattern

Any solution?

Thanks in advance.
