FilenameExtIn function

Declaration

function FilenameExtIn(const Filename: string; 
 Exts: Array of string = string; 
 CaseSensitive: Boolean=False): Boolean

Description

FilenameExtIn is a Boolean function used to determine if the file name in the Filename parameter uses one of the file extension in Exts.

Exts is an array type with the file extensions expected in the routine. Values in Exts can contain the '.' (Period) character in the extension, but it is not required.

CaseSensitive indicates if case-sensitivity is used when comparing the parameter values. When set to True, the comparison is limited to characters in the ASCII character set. StrLComp or StrLIComp is called to compare the value in Filename to the values in Exts.

The return value is True when Filename uses one the file extension in Exts. The return value is False when Filename is an empty string (''), does not include a '.' character that marks the start of the file extension, or does not use one of the values in Exts.
