There can be several reasons for this:
- foxpro cannot see the file
- you do not have user privileges to delete the file
- file is in use, etc...

Try something similar to this. It will attempt to remove ALL files from directory:

lsSpecialFolderPath =addbs(lsSpecialFolderPath)

oFSO = CreateObject("Scripting.FileSystemObject")
RELEASE atemp
FOR EACH oItem IN oFSO.GetFolder(lsSpecialFolderPath).Files
	Dime atemp[IIF(type("atemp")#"C",1,alen(atemp)+1)]
	atemp[alen(atemp)]=ADDBS(lcdir)+oItem.NAme
ENDFOR

if type("atemp")="C"
        ON ERROR wait wind time 0.5 "access denied, file "+atemp[ia]

	for ia=1 to alen(atemp)
		oFSO.Getfile(atemp[ia]).DELETE(.t.)
	endfor

       ON error
endif
