There are routines in both TC and MSC that do a file spec search (with pattern
matching) in a directory. I think the names are something like "findfirst" 
and "findnext" for TC and "_dos_find_first" and "_dos_find_next" for MSC. 
These routines merely use an INT 21 service.

Anyhow, every filename that matches the spec gets most of its directory info
such as file size and date put into a structure. So you can check the
appropriate fields for whatever purpose you need. This is also much more 
efficient that "fopen"ing a file, "fseek"ing to the end, "ftell"ing the 
position, and then "fclose"ing it.
