[Coco] Strange files

[Bill]

I took a look at my uploads directory on my FTP a while ago, and found this.


Volume in drive D has no label
 Volume Serial Number is 0B50-1DF0
 Directory of D:\FILES\COCO\UPLOAD

.            <DIR>     02/22/09   9:13p
..           <DIR>     02/22/09   9:13p
1_03_05_09_07_37_46       6,506,152 05/03/09   8:37p
1_03_05_09_7_38_17         2,794,923 05/03/09   8:38p
1_04_05_09_7_42_47         6,506,152 05/04/09   8:42a
1_05_05_09_10_10_19                       0 05/05/09  11:10a

Has anyone got any idea what these files are?
