Descargar Fat32 Format

[Karina Edling]

Irecently purchased a 32 GB USB 3 stick that was formatted with FAT32. I plugged it into my computer and attempted to copy a video file onto it. The file was over 4 GB however and it would not let me copy the file across because of the 4 GB file size limit imposed by FAT32.

After some googling, I found that I could format my USB stick to use exFAT which would mean I could put files onto the stick greater than 4 GB in size and the drive would work on both my Mac and my PC.

Natively, you cannot store files larger than 4 GiB on a FAT file system. The 4 GiB barrier is a hard limit of FAT: the file system uses a 32-bit field to store the file size in bytes, and 2^32 bytes = 4 GiB (actually, the real limit is 4 GiB minus one byte, or 4 294 967 295 bytes, because you can have files of zero length).

However, if you split the file into multiple files and recombine them later, that will allow you to transfer all of the data, just not as a single file (so you'll likely need to recombine the file before it is useful). For example, on Linux you can do something similar to:

Here, I use truncate to create a sparse file 6 GiB in size. (Just substitute your own.) Then, I split them into segments approximately 2 GiB in size each; the last segment is smaller, but that does not present a problem in any situation I can come up with. You can also, instead of --bytes=2GB, use --number=4 if you wish to split the file into four equally-sized chunks; the size of each chunk in that case would be 1 610 612 736 bytes or about 1.6 GiB.

Many file archivers also support splitting the file into multi-part archive files; earlier, this was used to fit large archives onto floppy disks, but these days it can just as well be used to overcome maximum file size limitations like these. File archivers also usually support a "store" or "no compression" mode which can be used if you know the contents of the file cannot be usefully further losslessly compressed, as is often the case with already compressed archives, movies, music and so on. When using such a mode, the compressed file simply acts as a container giving you the file-splitting ability, and the actual data is simply copied into the archive file, saving on processing time.

Expanding on Michael's idea, many compression utilities/formats support a "store" mode, where they don't actually do any compression. Most of those same utilities also support splitting into multiple archives. Combine the two, and you can split a file without wasting a bunch of time compressing it, especially if it's non-compressible data. I've used this technique myself to overcome the exact problem you're having.

One big advantage to doing it this way is that the compression format acts as a wrapper, keeping you from accidentally doing anything with only one part of the file. It also tends to be simpler for non-technical users. (Not everyone knows how to cat files, but almost everyone can open a zip.) It's also very obvious that it's a multipart file, since the file is formatted as such. Loose files may not look like a multipart file, especially if they lose their filenames somehow.

Of course, if you actually want to be able to work on the separate files, this doesn't work as well. This may be important if you don't have any "scratch space" to write the final file to. In that case, you should just split the file.

Another option not stated would be to use partitions. A USB flash drive is most often treated by the OS as a hard drive. Resize the FAT32 partition and make an exFAT (or other supporting filesystem) partition that is large enough to hold the file.

If you ever need to access the large file in place on the USB drive, this is probably the best solution. If all you need to do is transfer the file, and don't mind having to copy it to the hard drive to use it, the splitting solution is probably better.

This won't work if your USB drive is setup as a "super floppy," but this is increasingly uncommon. You can convert a "super floppy" into a hard drive format by using a partioning tool such as fdisk or gparted. But it will probably involve copying the files off, converting, copying them back, and then making the drive bootable again.

As answered by others splitting the file and joining works. But the easiest solution is to use ext 2/3/4 file system for your usb drive. It the native filesystem for linux. In windows use ext2fsd for reading the data. It also support write mode. Just install the free app on windows access file, no splitting , no joining.

It might be implemented because it is also used on (some) iPods that are widely popular, so even M$ Xbox360 seems to read it. With appropriate software on PC, IF it works on the PS3, you'd get get a universal solution.

I needed to move a 15.5gb virtual environment. I removed the partition on the usb key (32GB) and made a new one that was extn4 (linux), mounted it as 32GBkey moved the file. Booted the machine that needed the file using knoppix live (linux disc), mounted the key, moved the file.

I have found that using Adobe Bridge (if it is available to you) will bypass the 4GB limit on our servers. This can be done simply by "drag and drop" from the OS launcher into the bridge client window. Works for large (15gb+) video files where I work.

I have a 4.43GB .mkv video file on a FAT32 formatted 16GB USB3.0 flash drive playing on a 3rd gen Firestick via VLC Player (using an OTG cable to plug in the USB stick). I went between Macos Mojave and Windows 10 running in VirtualBox.

(Before staring make sure you have emptied your trash of any files you may have had on the USB flash drive as for some reason when you come to unzip the zipped files they will still register as occupying space on the flash stick which may result in you not having enough room on it. This happened to me.)

If you create a fat32+ volume instead, you can have a filesize up to 256gb minus 1 byte. Mainstream operating systems do not support it, nor are aware of the extension as described on wikipedia, but windows and the PS3 can still recognize and write to it, at a small risk of data-loss, unlike the open-source DR-DOS/OpenDOS enhancement project which is fully compatible.

FAT32 has a hard limit for how every file is listed (32bit field for file size). However, applications that bypass this limit use more fields. In theory, this can bypass the hard limit, but requires placement of the next fields immediately following the first, and linking the end of the first to the beginning of the next as if it were part of the file (it reads that end sector, and gets another file bitfield message from the second field) which is usually handled by PC operating systems alright, but not always.

Other programs move files in chunks of 600mb to 2gb and use a flag bit, then use multiple bitfields for the chunks, though all is seen as a single file; such is the case with adobe software, especially with video files. It segments the files, and creates a bitfield for each segment for video\audio that is read by the os as a single file. These files are simply wrappers, a folder of sorts that wraps around a set of images, or samples that are quickly cached into memory for playback. The DVD standard VOB is another great example that shows where this comes from and why. Its cut into chunks of quickly cached files for playback on DVD players. They use the old UDF1 or joliet format, which borrows from HFS, but uses mostly FAT capable lists. The file size limit is roughly 2gb, mainly for caching speeds of DVD player set-top-boxes. Most often it is in 1\10th to 1\5th of that limit, and multiplexed audio and video chunks are cached together very quickly, for playback.

The answer to this problem isn't complex, but it isn't one size fits all. For the specific question, use a splitter program; WinRar, 7zip are great, and have a gui. It's a simple answer and works well. The OS (operating system) will set the file to use multiple fields, and multiple chunks, but it will be seen as one file after the merge. With many compressed video files (almost every format is a compressed format by one algorithm or another), the read speeds for FAT are fast enough to playback on most smart TV's, or minimal OS Console systems (PS3\4, XBOX, etc). Other files like ISOs etc, not as capable unless in DVD format for video, which is a heavily cached format anyway. For game ISOs, check ntfs, and a few other formats your computer can build on the USB drive, and then try it with no split actions.

As the OP said 'for a PS3', the answer has to relate solely to FAT32, as this is all you get with PS3. As for Linux users, the answer can be found in EX4 partition formatting, and of course, NTFS with Windoze.To move files from EX4 to NTFS via Samba is easy. If moving a file requires 'jumping through hoops', you really should consider 'am I formatting my partitions properly to handle the files I need to handle on a regular basis?' That said, it's also nice to have more than one computer around that can process what you need to, how you need to, too. (This, coming from someone that just formatted a USB 32gb dongle in FAT32, only to find 10 minutes later that I needed to store a 15gb .img file on it, and had to move everything off it, change the partition format, and move it all back onto it).

Fixes: Begin by shrinking the large volume to less than 250GB using the RESIZE/MOVE Partition function in Partition Resizer. Right-click the large volume, convert it to FAT32 in the next step, and then expand the FAT32 volume to your desired size using the software. There is no data loss during this process.

FAT32 (File Allocation Table 32) is an older file system compatible with a wider range of devices, such as digital cameras and game consoles, with a maximum file size limit of 4GB and a maximum volume size limit of 2TB.

When attempting to format an NTFS partition to FAT32 using Windows built-in tools, the operation is not permitted because it requires erasing all data on the partition. Additionally, NTFS features not supported by FAT32 can result in data loss or corruption when converting. Third-party tools are available for this conversion but should be used cautiously and only after backing up your data.
