What means 'a large number'?

I'm reading that the root directory of a FAT (16) drive can only hold
512 folder/files, whereas those folders can hold 65000.  Also you may
need to use 8.3 filename

Maximum file limitation on digital picture frame internal memory

1. You found out the hard (but sometimes the best) way that which is
well known, namely fat16 systems have a fixed filename directory size
and hence a limit to number of files in root directory.

2. You have successfully confused me by your statement that reducing the
filename length didn't change the number of root directory files.  Each
8:3 filename requires 32 bytes, divide this into the directory size and
voila, you get the file limit.  Using long filenames should reduce this
number, something you are saying didn't happen, so I am wondering if the
long filename is being retained.

3. A sub-directory will hold many files, I believe the limit is around
65k, but again, long filenames will reduce the number.  In any case, you
will run out of disk space long before you would have to worry about a
directory restriction.

He's using OE's version of QP QuotedPrintable, which is a bad idea:

OE/ Tools/ Options/ Send tab - News sending format - Plaintext settings
button - Message format section - MIME options - Encode text using -
should be None instead of QP.

When other (native) OE users reply to OE's QP, they don't quote it and
they wrap it differently than non-QP.

My OE handles it differently because of my OEQF QuoteFix.

I have a 256M USB 'thumb drive.

I have tried to transfer a large number of pictures to it. The aggregate size of
the files is only about 6-7M, however I appear to be reaching some limit on the
number of files that can fit on the drive.

The driver is formatted FAT.

Is there some architectural limits on the USB drives?

I even attempted re-formatting and still got the same results.

Joe, replying to your posts never "quotes" your post. It works with
any 
other post, what are you doing?

Anyway I have XP and a 256 MB thumb drive and see no such problem. What I 
have seen is a problem transferring over a certain filesize to a thumb 
drive, although not with mine (I have copied 200MB files back and  forth). 
The same drive worked fine on win98, and Win2K also.

The case where I had a problem was when neighbour boy was trying to bring a 
~1GB video presentation to school, too big for a CD,and none of us had DVD 
burners at the time, so I suggested they buy a cheap 2GB thumb drive (fry's 
had them on sale). The copy crapped out around 700MB every time. I 
reformatted the drive to NTFS (it shipped with FAT), tried DOS copy, and 
same problem, never did figure out what was wrong.

There is a limit to the number of files (something like 256 or 512,
even less if using long filenames) that can be put in the root
directory of a FAT filesystem.  Make a subdirectory and place the
files there.  (Even better might be to make several subdirectories
and divide them up in some logical groups, if possible.)
