The easiest would probably be to fire a DIR command from your application:
DIR SpecificDir\*.* /ON > specdir.txt // Order by Name
DIR OtherDir\*.* /ON > otherdir.txt
Then read the TXT files and compare the filenames after extracting it
from lines.
Since I am not a VFP but a Clipper/VO/X# developer hopefully this will
give you an idea how to do it using the VFP language syntax in X#.
LOCAL aSpecDirFiles, aOtherDirFiles AS STRING[]
LOCAL aMissing = ArrayNew() AS ARRAY
aSpecDirFiles = FileToStr("specdir.txt").Split(CR_LF)
aOtherDirFiles = FileToStr("otherdir.txt").Split(CR_LF)
LOCAL nPos = 1 AS INT
FOREACH line AS STRING IN aSpecDirFiles
SpecFile = SubStr(line, <start>, <end>)
OtherFile = SubStr(aOtherDirFiles[nPos], <start>, <end>)
DO WHILE OtherFile < SpecFile
AAdd(aMissing, OtherFile)
nPos = nPos + 1
OtherFile = SubStr(aOtherDirFiles[nPos], <start>, <end>)
ENDDO
IF OtherFile = SpecFile && We have a match
nPos = nPos + 1
ENDIF
NEXT
FOR i = nPos UPTO aOtherFiles.Length
AAdd(aMissing, SubStr(aOtherDirFiles[i], <start>, <end>))
NEXT
Hope this helps.
