No wonder Gentoo depends so heavily on Python.
 
Here's a list of some of the files in a directory:
 
file_999
file_1000
file_998
file_200
file_2000

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

 
 
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)?
 
 
yeah, crickets, just like I knew
 
 
-------------------------------------------------------------
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.

BTW, have you ever used awk?

(Also: see ls -v)

-------------------------------------------------------------
D:\>python temp.py
file_200
file_998
file_999
file_1000
file_2000
 
file_2000
file_1000
file_999
file_998
file_200

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:
 
D:\>python temp.py
0.13s to read 191490 files
First file is 730478
Last file is  943773
