It sounds as though you need information about "wildcards" in DOS.

AFAIK DOS (and WINDOWS) recognizes only 2 such characters: * and ?

Thes wildcards can be used in filenames but not in directory (path)
names.

* stands for any number (including 0) of characters

thus "P8*.jpg" would match "P8260019.jpg", "P8260020.jpg",
"P8home.jpg" and "P8.jpg" but not "P9260019.jpg"

"fred.h*" will match "fred.ht", "fred.htm", fred.HTML" but not
"freda.htm"

? stands for a single character

thus "P?260019.jpg" matches "P8260019.jpg", "P9260019.jpg",
"PX260019.jpg" but not "P8060019.jpg"

The simplest way to learn about wildcards is to open an MSDOS window
and try doing a dir with various combinations

eg dir ???.* (lists all 3 character filenames with any extension)
dir *.?? (list all files with 2 character extensions)

But to bring this back to Delphi, you can use the * and ? wildcards in
the Path parameter supplied to the FindFirst function.

eg FindFirst ('c:\temp\*.jp*', faAnyFile, MySearchRec) to locate all
JPEG files in the C:\TEMP folder
