This is more of a curiousity thing, but recently I had errors when copying files to my thumb drive because I had reached some file limit.

What exactly is this limit?

I had reached some file limit, Don't you think it could help if you could tell the exact error message? – Bibhas Jan 30 '12 at 10:15
Why don't you look at the FAT32 specification? It lists all those details. – Tom Wijsman Jan 30 '12 at 11:31
If you have 65k files in a single folder you have a problem. You unliikely have 268 million files on the disk, if you do, get rid of some of the files. – Ramhound Jan 30 '12 at 12:28

For FAT32, maximum number of files in a single folder is 65,534.

Additional info for FAT32:

  • Maximum disk size: 2 TB
  • Maximum file size: 4 GB
  • Maximum number of files on disk: 268,435,437
