Here's a list of some of the files in a directory:

Why do you prefix them with "file_"?  Why not name the files
by article number, like other nntp software does?

 
 
That was just my example.  They're actually prefixed with the name of
the newsgroup:
 
comp.lang.c_551568
comp.os.linux.advocacy_1239605
etc.
 
No extension.
 
I use SuckMT for Windows to download them.  Well, I try to, but it
doesn't work too well.  It always crashes after downloading around 4K
message files.
 
 
 

How about some of your 'extraordinary' C to read the directory and list
those files in ascending order (because they need to be processed
sequentially by nbr)?

import os
msgdir = "D:\"
filearr = []
for pfile in os.listdir(msgdir):
if '_' in pfile:
filearr.append(int(str(pfile).split('_')[1]))
for filenbr in sorted(filearr):
print("file_" + str(filenbr))
print()
for filenbr in reversed(sorted(filearr)):
print("file_" + str(filenbr))

 
You assume they are prefixed with "file_" instead
of, say, "foo_" -- but you print them as "file_xxx".
Tsk, tsk, tsk.

 
?
 
You're not equipped to tsk my programming.
 
That was an example for Feeb.
 
The real thing:
------------------------------------------------------------------------
msgdir = "D:/computer/dev/usenet/suckmt/posts/blocknews/" + sys.argv[1]
+ "/"
msgfile = ''
filearr = []
for pfile in os.listdir(msgdir):
if '_' in str(pfile):
filearr.append(int(str(pfile).split('_')[1]))
for articleID in sorted(filearr):
msgfile = grpName + '_' + str(articleID)
....
------------------------------------------------------------------------
 
In the first line, sys.argv[1] is my abbreviation for the newsgroup
(cola, clc, cdma, etc) passed in from the command line.  In the last
line, grpName is the full name of the newsgroup.  ID, abbreviation,
group name and other info is in a db table.
 
 
 

BTW, have you ever used awk?

 
A tiny bit.
 
 
  > (Also: see ls -v)
 
Yeah, I know ls will list the files in the correct order.  I couldn't
make it happen using Windows dir, though.
 
Windows File Explorer and thunar and Nemo showed them in the correct
numerical order.

It can also be done in fewer lines with the glob and regex modules, and
using list comprehension.

By the way, I have a folder of 191K+ such files, and that code runs in:

Please don't feed the "C Programmer Extraordinaire" any hints.
 
Note: I do know how to write C to scan directories and list files and
check file types and open and read the contents, etc.

Feeb does not.

I looked at those, and had to do a double-take with the
second one.

Calling "file" is "cheating". ;)  You can get crafty with
a lookup table and stat(2).

I mention this mainly because if Laughing Boy was
capable of reading your article, he'll surely launch
into a cackling fit that might brake his brane.  (That
is...if he understood the program, which he probably wouldn't.)

(Regarding article lookups and such, I use a shell script that calls
openssl(1) s_client to connect, log in, and leaves me with
the NNTP prompt...a place at which Feeb would be lost.)
