How big is the file you are transferring ?
The FAT32 format does not support single files larger than 5GB, so if you have a file larger than 5GB you cannot put it on your FAT32 thumb drive. Most thumb drives and other portable media devices use FAT32 format, so this setback makes large files less portable, and that just won't do. Get around this problem by compressing the of the file or by splitting the file up into multiple pieces.
Create a folder for your RAR file and insert a copy of the original file into this folder. RARing a file separates it into multiple pieces, so creating a file specifically for your RAR file will keep the files together allowing you to move one folder to your FAT32 device instead of having to locate and move multiple files. Right click the large file that you want to put on a FAT32 device. Select "Add to archive" from the menu that appears to the side. Select "RAR" from the "Archive Format" located to the left of the menu. Click the arrow next to "Split by volume, bytes," and select "CD 700: 700mb." This will create a new file for every 700mbs, meaning your your one large file will be separated into many 700mb files that can be put back together as a single file later. Click "OK." Put the folder, containing your newly separated files, onto your FAT32 device after WinRAR has finished separating the file. b> Zip File
b> Right click the large file you want to put on a FAT32 device. Select "Add to archive" from the menu that appears to the side of the file. Click "OK" on the next menu. This menu allows you to customize the compression settings. The only option you need to change is the "RAR" selection to "ZIP" in the "Archive Format." The rest of the default settings will work fine, so there's no need to change anything else. The zipped file will appear in the same folder as the original. Delete the copy of the original large file from the folder and put your newly compressed file on your FAT32 device after the file has completely compressed. The time it takes for the file to finish compressing depends on the of the file. Hope this helps. http://www.all-freeware.com/getfreeware.html?pid=109090&mirror=1
