Blog Perché non riesco a copiare i file di grandi dimensioni sulla mia USB?

Problema
Hai una chiavetta USB da 8GB. E' completamente vuota e vuoi copiare un file di grandi dimensioni, diciamo 5GB. Tuttavia continui a ricevere il messaggio ''spazio disponbile non sufficiente'' nonostante vi sia spazio libero in abbondanza sulla chiavetta.

Perchè appare questo messaggio?
La maggior parte delle USB sono formattate come 'FAT32 File System'.  Questo sistema è stato creato nel 1995 e, per ragioni di protezione dei computer, impone limitazioni nella copia di un file sulla memoria se esso supera i 4GB di dimensioni - nel 1995 erano davvero molti dati!

Tuttavia, c'è un sistema chiamato 'Extended File Allocation Table (ExFAT)' creato da Microsoft che fornisce parte della soluzione per gli utenti di Microsoft Windows. Qui a Flashbay usiamo la formattazione ExFAT per le memorie da 64GB che contengono file singoli più grandi di 4GB precaricati al loro interno. Tutte le altre capacità vengono formattate con il sistema FAT32.



Soluzione
1) Verifica che la chiavetta USB sia vuota e di aver salvato i tuoi file al sicuro sul  PC o laptop

2) Entra nella cartella 'Risorse del Computer', clicca con il tasto destro sull'icona del disco removibile e seleziona 'Formatta'.

3) Si aprirà una finestra con le opzioni di formattazione. Seleziona dal menù l'opzione ‘ExFAT’. Potrebbe esserci anche l'opzione NTFS, anche questa può essere utilizzata in alcuni casi. Clicca qui per maggiori informazioni (in inglese).

4) Fai clic su 'Start' per dare avvio al passaggio da FAT32 a ExFAT. Ciò richiederà circa 2 minuti.

Ecco fatto. Ora potrai copiare i file di oltre 4GB sulla tua USB, se c'è abbastanza spazio, naturalmente!

Same issue happened to me sometime back and what i have tried is copying the whole pst, whether 5 GB, 10 GB or even 25 GB data , the whole file as it is gets copied to mobile very easily through datacable.

The only thing is mobile must have that much space which nowadays every mobile comes with huge storage atleast of 64 gb. 

So guys try this

Hi Madeleine, 

Thanks for your question.

Some of the TV Shows you're trying to copy to your Flash Drive may be more than 4GB each. If that's the case, you need to follow the steps listed in this blog post - if you haven't already done so.

If you're still receiving an error message, your Flash Drive may be faulty. It's highly unlikely that 4 TV Shows will consume the entire 64GB capacity.

I hope this helps.

Many thanks,

Chris at Flashbay

Thank you! Mine was in exFAT already but the kilobytes were at a very low default setting. I have folders by the year for family photos that I am storing. Still you were able to teach me something new and I found the screen that helped me adjust to what I needed.

I need to copy mp3 files from an 8gb USB drive to a 4gb USB drive. The 8gb has about 6gb of mp3 and I want to transfer as much of the files that can fit into the 4gb. Is there a way I can drag and drop the full amount and let some software just transfer what fits?
Graham Ecob | 30 Nov, 2021
Thanks - I was at a loss to understand why it wouldn't copy a large file.
Beth | 16 Sep, 2021
This worked perfectly and took less than a minute!! Thank you for the great information :-)
Steve | 25 Aug, 2021
Thank you.
Your info was great.

You may need to increase the unit allocation size in order to transfer large files. Mine was set to Exfat128kb and it still wanted more before I could move a 5 gig file.
Deepak | 07 Jun, 2021
Its just easy.  Open your your Hard drive as a portable device and then transfer.  Easy peasy.
Sara | 01 Feb, 2021
Hi Chris
Thank you for your help. I reformatted the usb again to exFat and this time it worked.
Chris , Flashbay | 01 Feb, 2021
Hi Sara,

Thanks for your question.

Without knowing all of the details, it's hard to give a completely accurate answer.

exFAT can handle file sizes of 20GB and above, so it may be an issue with the available space on your drive (unlikely, as I suspect you've already checked this). Or it could be an issue with the actual file you're trying to move. 

It may also be a conflict with your antivirus software, in other words the software may be 'blocking' the file move. Please check your software settings.

Another option is to try formatting the Flash Drive to NTFS if you can, which is a more modern file system, compared to exFAT.

I hope this helps.

Many thanks,

Chris at Flashbay

I purchased a WD eaststore 128GB flash drive. My 128 GB flash drive is already formatted to exfat and it still won't let me move an 20 GB file. 

Please advise.

I was also unable to copy files to my Hard disk the file size was 8 GB and hard disk was 150. I didn't knew what was the problem at that time. After searching I found that it supported FAT32 file type and more than 4 GB file could not be copied. After trying many software which I didn't found satisfactory I found GS Richcopy 360. Although its a paid software but its just awesome. I copies the file file permissions too. Not only that it also solved my problem of long path name. Its other features include multi threaded file transfer, pre scheduled file transfer, email notification when the transfer is done and many more. Try it, its awesome!
Kumar | 08 May, 2017
Well, I too had this same problem and I thought to myself that Windows doesn't math it seems! But after knowing the fact that these drives are FAT32 type and maximum file size is 4GB I got my answer.  After knowing the fact, I started to search answers for it and then one site I found a software named GS Richcopy 360. Reviews were quite impressive so I tried it and it did solved all my problems including long path name support. Now, I have been using this software for around 2 years and its just amazing. Try it hope it helps!
