I ran into something strange today
Vericut released V9.4 this morning
I downloaded the V9.4 zip file which came in at 5.28g

I tried to save it to 2 different flash drives so I could take it home.
One was a new 32g Sandisk USB drive.
the other
a Samsung 256g USB "C" with about 6g of data on it.

In both cases the transfer failed throwing an error stating the file was too big for the drive.
I unzipped the file into a folder with a file size of 5.35g and it transferred to both
flash drives without issues.

Our IT guy tried this on his PC and got the same results I did.
Anyone ever seen anything like this before???
Could the fact that it is a password encrypted zip file have anything to do with it?

Can you uncompress it, and re-compress it without a password, then try saving it to the USB?

That is a good idea and an interesting experiment
I will try it

I got the same results

The error window says

Any error occured copying "vericut v94.zip"
There is not enough space on the disk (112)

The flash disk is a Samsung USB "C" 256g
7.34g in use with 238g free space

I found the answer
QuoteSometimes, when you try transferring a large file to your USB, a notification "The file is too large for the destination file system" may pop up. You spare no effort to reduce the size of the file but the result still fails you. Why does this bothering issue frequently come? To understand the inner secret, we must talk about file system first.

What is file system? File system usually controls the way files are stored, identified, and organized in a drive. On Windows based computer, the commonest files systems are FAT32 and NTFS. NTFS allows the maximum size of a file to be 16TB while its counterpart FAT32 only supports 4GB file size. So, now you should understand why the notification mentioned above always pops up on your screen – your USB drive's partition is formatted in FAT32 while your transferred single file is beyond 4GB.

That was going to be my next question, what format it's in.

gcode

Both the flash sticks I tried were FAT32
That's a relief, I though something was wrong

Hmm, interesting. I've encountered this once before but never resolved it.

So, does it make sense to format some USB drives to NTFS?

If you routinely need to put files bigger than  5g on flash drives it couldn't hurt.
This is a first for me, though I suspect it will be more common.

Yes, the file sizes are getting larger and larger, so I agree. It couldn't hurt.

I might take a couple and convert them to NTFS and see how they work.

The only drawback could potentially be that sometimes I used one or more of the USB drives to play media on my home theatre, and I suspect that the receiver wont handle NTFS formatted drives. No biggy though having some formatted NTFS and others FAT32.

The only concern is if you routinely plug the USB into non-windows computers, such as a lot of CNC machine controls, 3d printers, older/other OSes, etc.   A lot of older ones can't handle NTFS, even though they should, it's been the better option for the past 20 years! 

That's why everything comes formatted as Fat32, everything made since DOS 6.22 can read it.
