In this video tutorial, we see how to connect Commodore 1541 floppy disk drive to Windows 10 PC. From minute 7:13, we also see how to use the various software that are used to transfer files: OpenCBM and CBM Transfer (written CBMXfer). The XUM1541 interface (sometimes pronounced Zoom1541) allows you to connect the original Commodore 1541 floppy disk drive to the USB port of a normal Windows PC, to transfer files without using the Commodore 64!

All'inizio del video, spiego anche come installare i driver dell'interfaccia XUM1541, nonché come installare i software OpenCBM and CBM Transfer (written CBMXfer), correctly, on Windows 10. You can find the details in this article.
If you are interested in assembling the XUM1541 kit, you can consult this article.
XUM1541: Connect the Commodore 1541 floppy disk drive to the Windows 10 PC
The Commodore 1541 floppy disk drive connects to the XUM 1541 interface via an IEC serial cable. The XUM 1541 interface connects to the Windows PC via the USB port. I recommend connecting all cables with the PC and drive turned off. After connecting everything, you can turn on the PC.

Before starting the CBM Transfer program, the Commodore 1541 drive must be turned on, otherwise the software will not recognize it. So, only after you have everything connected and turned on, you can start CBM Transfer (CBMXfer).


List of files on disk (Directory)
Collegare il floppy disk drive Commodore 1541 al PC Windows 10 è molto utile per consultare l'elenco dei file presenti in vecchi dischetti, nonché trasferirli su PC. Dopo aver premuto il pulsante Directory on the right, the computer connects to the Commodore 1541 and receives information. Ricordatevi di collegare l'interfaccia XUM 1541 ed accendere il drive prima di avviare CBMXfer.

L'elenco dei file, presente alla destra della finestra di CBM Transfer (CBM Drive on X-Cable), populates with all the names on the disk.

Trasferire un file da dischetto 5" 1/4 a PC Windows 10
Dopo aver consultato l'elenco dei file a destra della finestra di CBM Transfer (CBM Drive on X-Cable), è possibile selezionare un file, cliccandoci sopra con il mouse. Per trasferire il file, presente su dischetto, verso una cartella specifica dell'hard disk, bisogna dapprima selezionare la cartella di destinazione, utilizzando il pulsante a sinistra con i tre puntini, nella sezione Directory on Local PC.
To start the transfer of the selected file, you must press the button Transfer: the green arrow pointing to the left. The file passes from the floppy to the PC.


Dopo aver terminato il trasferimento, il file risulta presente nell'elenco a sinistra, nonché nella cartella dell'hard disk del PC.
Trasferire un file da PC Windows 10 a dischetto 5" 1/4
Connecting the Commodore 1541 floppy disk drive to the Windows 10 PC is also useful for copying files to disk, which we can then use with the various Commodore to which the Commodore 1541 floppy disk drive can be connected.
Per trasferire un file, presente sull'hard disk del PC, verso il dischetto, bisogna dapprima selezionarlo dall'elenco a sinistra di CBM Transfer (Directory on Local PC) and then press the button Transfer, the one with the green arrow on the right.

Il trasferimento del file si avvia e, dopo qualche secondo, il file sarà presente su dischetto e visibile nell'elenco a destra. Nell'esempio, ho selezionato il file della prima puntata del Basic language course.

After transferring a file to disk, it can be loaded directly from the Commodore 64 (and from the other Commodores to which the 1541 floppy disk drive can be connected).

Creare l'immagine D64 a partire da un floppy disk fisico
Now let's try to create a D64 file (an image of a disk), starting from the physical disk present in the Commodore 1541. It is as if we were making a complete backup of the disk, sector by sector, track by track, on a D64 file.
We press the button Directory to view the list of files on the disk, but we do not have to select any.
Without any files selected, we can press the same button Transfer which is used to download a file, the one with the green arrow on the left. A disk image is created with the name of the file we have just indicated.

It may happen, especially if the disk is a little damaged, that this D64 image creation operation crashes or returns errors. In case it crashes, you will have to press the button Abort, then disconnect and reconnect the XUM1541 adapter and also turn off and turn on the floppy disk drive 1541.

Se non ci sono errori, e se il disco è in buone condizioni, l'immagine D64 viene creata in meno di due minuti.

Il file D64 appena creato, risulta disponibile sull'hard disk del computer, per essere caricato da un emulatore, oppure per essere trasferito su un altro dischetto. Tutti i file D64 hanno una dimensione di 171KByte.

Connect the Commodore 1541 floppy disk drive to the PC to transfer a D64 to a physical disk
E' possibile creare un floppy disk 5" 1/4 a partire da un file D64 senza utilizzare il Commodore 64: semplicemente, si collega il floppy disk drive Commodore 1541 al PC, mediante lo XUM1541!

Si parte da un file D64 presente nell'elenco a sinistra di CBM Transfer (Directory on Local PC) and then press the button Transfer, the one with the green arrow on the right. It is as if we were restoring a backup of an entire disk.
Il computer chiede conferma dell'operazione, anche perché the disk in the Commodore 1541 floppy disk drive will be overwritten with the new data, traccia dopo traccia, settore dopo settore. E' necessario inserire un disco già formattato, anche non vuoto.

Dopo aver confermato, l'operazione di trasferimento inizia ed il dischetto verrà sovrascritto con i dati presenti nel file immagine D64.

Dopo aver trasferito l'immagine D64 in un floppy disk 5.25", è possibile utilizzare il dischetto con un computer Commodore vero.
File Operations D64
From the list on the left of the CBM Transfer window, we can also open the D64 virtual disks. Double click on the D64 file to open.

L'elenco dei file a sinistra cambia colore di sfondo e passa da Directory on Local PC a Disk Image File.

E' possibile effettuare diverse operazioni con i file contenuti all'interno del disco virtuale D64. E' possibile delete a file with the button Of sotto all'elenco dei file. Si può rename a file, using the button Ren. E' anche possibile consultare il contenuto di un file con il tasto View.
Using the buttons Transfer (the two green arrows we saw earlier), we can too trasferire dei singoli file dall'immagine D64 ad un dischetto fisico e viceversa. Ovviamente, deve esserci spazio sufficiente all'interno del disco (se si stanno copiando i file da D64 a floppy disk) o all'interno dell'immagine D64 (se si copiano i file da dischetto a D64).


You can also transfer files between two D64 images: you need to open the images on the left and right of the CBM Transfer window. In the left part, we have already seen how to open a D64 file. In the right section of the window, you can click on the yellow button Local PC, e poi fare doppio click su un file D64. L'immagine del disco si apre nella parte destra della finestra.

Both lists are named after Disk Image File. Using the buttons Transfer (the two green arrows), we can also transfer individual files between the two D64 images.
OpenCBM, CBMXfer: how to rename a file on diskette
Per rename a file presente su dischetto, bisogna dapprima selezionarlo nell'elenco a destra di CBM Transfer (CBM Drive on X-Cable). Then, press the button Rename. Finally, type in the new file name.

The command Rename it is also available in the left part of the window, relating to the files on your computer.
OpenCBM, CBMXfer: delete a file from the disk
Per delete a file presente su floppy disk 5" 1/4, bisogna dapprima selezionarlo nell'elenco a destra di CBM Transfer (CBM Drive on X-Cable). Then, press the button Scratch. Ovviamente il computer chiede conferma dell'operazione. Dopo aver confermato, il file verrà rimosso dal disco e non sarà più visibile nell'elenco.

E' anche possibile cancellare dei file presenti sull'hard disk del computer, tramite il comando Delete in the left part of the window.
Connect the Commodore 1541 floppy disk drive to your Windows 10 PC to view the contents of a file
On the right of CBMXfer is the button View. Dopo aver selezionato un file dall'elenco a destra, è possibile visionarne il contenuto.

The command View it is also available in the left part of the window, relating to the files on your computer.

Formattare un dischetto Commodore 5" 1/4 da PC Windows 10
To format a disk (in CBM format), you use the button Format on the right of the CBM Transfer window. The computer asks for the disk name and ID, then formatting starts. The formatting process is governed by the Commodore 1541 floppy disk drive, so the computer remains free. However, the disk cannot be accessed, as it is busy formatting. Warning! Formatting deletes all data on the disk!

When we hear that the drive has stopped, the formatting is finished. We can consult the list of files by pressing the button Directory. It must be empty.

Hi, I follow you on facebook and youtube, congratulations and thanks for the videos posted, I wanted to ask you a question I have to buy new empty 5.25 floppies but I get confused between the various types and brands, Double sided and more, I ask but it is possible use any 5.25 floppy disk for the 1541 II drive or do I have to buy specific floppies?
Thank you and I wish you a very happy new year, greetings!
Hello and happy new year! Thank you very much for the compliments! For 1541, I use DS DD floppies, which means double sided double density. They are also found on eBay, as well as by private sellers in various Facebook groups.
As floppy disks are generally old, I recommend looking at the surface of the disk before inserting it into the drive. It must not have stains, dirt, dust and streaks. It must be smooth. If the disc is dirty or scratched, do not insert it into the drive.
Great article, just what I was looking for.
