Hi i have a 16 gb usb drive. i want to transfer file to my usb drive. The files do transfer over to my usb drive but when i safely remove the usb and reconnect the usb the files seem to get mixed up and messed up and also some files names change to a square font. Why does happen and How do i fix this?

Do you mean you are copying files already on the internal hard drive to a USB flash drive and the file font is changing?

What type of files are they?

Does it happen no matter what size the copy is?

yes it happens on whatever size the copy is. i have tried chkdsk on the usb flash drive and formatting the usb flash drive and tried to recuperate the files on the usb flash drive by using a recovery software but the problems persists. The files seems to always mess up and all mixed up.

My apologies. I was thinking it might have something to do with the amount of available RAM.

There is a 4GB size limit with FAT32. Is the USB flash drive FAT32?

Also, when using FAT32 there are a finite number of files that can be written to the root directory of the partition. I suggest that you use folders and sub-folders for the files.

Using folders won't help if files are larger than 4GB but will help if there are too many files in the root directory of the partition.

yes its fat32. the fonts changing happens in the subfolders. when i transfered the files. i made folder and subfolders for the different files, such as i made a folder for games and in there subfolders for each game. Then created another folder for emulators and subfolder for each kind of emulator

USB devices may not work correctly when they're connected to certain USB ports e.g. ports in a hub or on the front of a desktop case. If you have a desktop computer, you may have an IRQ sharing problem you need to fix, or your power supply may be starting to fail.
See response 3 in this:

Also - if you are using a USB extension cable, some of them have inadequate wiring and will not work properly with some USB devices.
......

If that's okay now, you may have data damage.

Programs you can try to recover your data, if your USB port you have it plugged into is okay.
The most frequent reason people can't access data (or experience data damage).

Then the flash drive itself may be failing. There are utilities to test them if they are brand name drives.

As a test try making a folder elsewhere on your internal drive and copy something to it to see if the data corruption occurs.
