See my EnumDirs unit.
It does simply that. You can set include and exclude masks.
Masks can be case-sensitive or not, unixtype or windowstype, just set
the appropriate option
(I use this unit as a base for my backup program (see sources at
http://home.tiscali.nl/~knmg0017/software/sbp_bron.zip for example).
The unit is documented in the sourcecode.
You also need extmasks.zip (and possibly fpc_patches.tgz if you don't
use fpc 2.3.x), they ar all on the same page
TDirEnumerator = class(TCustomDirEnumerator)
var Enumerator: TDirEnumerator;
Enumerator := TDirEnumerator.Create;
Enumerator.Path := '/';
Enumerator.MaskList := '*';
Enumerator.Options := [soRecursive, soIgnoreErrors];
Enumerator.Attribute := faAnyFile or faSymLink;
Enumerator.FileHandler := @DeleteTheFile;
This would nicely delete all files (in the DeleteTheFile method) on your system.
Run it as root ;-) to have fun
(Possibly the cals to FindFirst/FindNext should be replaced by
I did not test this, as I never needed it, and I wrote the unit befoer
the switch in LCL to UTF8)
