You can define your own filename regulation to customize the downloaded filename:

You can use these variable in your filename regulation and use + to link them:

Substring

For string type variable, you can use (start position, length) after the variable to get the part of the string, for example, your project name is Celebrity desktop, the PNAME(0,9) denote Celebrity, if start position is -1, means get substring from right to left, e.g. PNAME(-1,7) denote desktop.

Uppercase & Lowercase

For string type variable, you can use U_ at the start of variable to make the result string all uppercase, L_ for lowercase, T_ for only first character uppercase and other character lowercase. for example, T_PNAME(-1,7) denote Desktop.

Instead '/' in string

If you use PATH or RPATH in your regulation but won't create directory in your picture path, you can use _ or - at the end of PATH or RPATH to instead the '/' with '_' or '-',  e.g., if the PATH=/images/award/ , PATH_ denote _images_award_, PATH- denote -images-award-.

Fixed string

You can use "fixed string" to insert a fixed string into result.

Sequence number

You can use DIGIT(start from) to make your picture filename sequenced, e.g. your project name is Celebrity desktop, the PNAME(0,9)+DIGIT(0001)+"."+TYPE denote Celebrity0001.jpg, Celebrity0002.jpg......
