File to large ???
 

I am trying to update the sat nav maps in my car. I have to download the file to my PC and then copy it to a usb flash drive to slot into the usb port in my car to update.

I have used the same 32gb flash drive twice in the past two years without any problems.

The file is just under 15GB and my drive is a 32GB capacity.

I am absolutely certain that on the previous times I used this drive I just copied the files across without any problems using FAT32 formatting on the usb drive.

Now every time I try to send the files the drive I get a 'File to large' warning. Following advice I set the format to NTFS and the files transfer perfectly. The only problem is that when I try to install this update in my car the system does not recognise it.

As already stated I am 100% certain I was able to copy the same size of file this time last year and the year before using FAT32.

Any suggestions?

Jim.

Fat32 has a 4GB limit

Try exFat

This is what I can't understand, I am 100% certain I used this same flash drive with FAT32 on two previous occasions without any problems.

I can transfer it to the usb stick by formatting to NTFS but the software in my car doesn't recognise it.

EDIT. Just noticed on the BMW portal that it now advises using a 64GB fat32 drive.:shocked:

Are you sure you don't need to extract it? I have a Ford and the software download comes as a big ZIP file that then gets split up into multiple files on extraction which are all smaller than the size limit for FAT32

Certain, this is the 3rd time I have updated the map and it worked perfectly the first two times but it did specify a 32GB USB drive, this time the instructions on the web portal now say a 64GB FAT32 stick is required.

Re: File to large ???
 

Was it 1 file or many when you did it last. The size of the stick isn't the issue here. You can't put more than a single 4gb file on a FAT32 file system.

Has been said already, if it is a single file then you need to extract it then put it on your stick (or extract the file to your stick).

Look at the file itself, if it's 1 file, then extract it, then check the size of the total files. If it is not 1 file but many and it exceeds 32gb then yes you need a bigger stick.

The trouble is as the title of this thread states... 'File' too large. Meaning 1 file, so extract it first.

Re: File to large ???
 

There has to be an element of doubt seeing as all evidence put to you tells you it is impossible to have a file bigger than 4GB on a Fat32 file system.

What extension does the file have? as others have said there must be another step to take

Found a video showing the copy process being done by a BMV update manager and not a simple copy and paste. Is this the case with your car?

Even the instructions on the BMW site tell you to copy via the map updater app

Re: File to large ???
 

My car is a 66 reg The update app is for models just after that date. On mine you have to use the BMW Download Manager App, download the file and then transfer to usb, slot into the car usb port and update. I know it doesn't sound logical but I am adamant that this process has worked perfectly on two previous occasions with this exact same usb stick.

The downloaded file is for some strange reason just labelled 'File' ???

Re: File to large ???
 

doesn't the app transfer it to the USB?

Re: File to large ???
 

No, this is the download instructions from the BMW portal

Re: File to large ???
 

As it's a single file, download 7-zip (free), download your file or locate the file, extract it, then add it to the stick.

Re: File to large ???
 

That does not say it does not though. I do not see it saying you have to

The attached image shows a select USB stick on the manager

Re: File to large ???
 

I haven't got a 64GB stick to try but getting one later.

I know I am not in the first flush o of youth by my marbles are definitely al in place. I did use the same stick and same method of download to hard drive, right click on file and select Send To, the only difference this time is the instruction to use a 64GB FAT32 drive instead of a 32GB drive?

I thought there may be a way to download it directly to a flash drive but the Download Manager App will only allow download direct to your to your PC's main drive.

Re: File to large ???
 

this is from a forum post where it clearly says he used the manager to copy the files

I put it to you that because you had a stick large enough to do it last time the manager copied the data over and not you manually. All evidence points to the manager copying over the data and FAT32 has never been able to deal with file sizes greater than 4GB no matter how much you try to convince yourself and the rest of us differently. Sorry for bluntness

if you read here there is a post that says it says it is a zip which the manager extracts

Try changing the .file to .zip and see if it extracts for you

Re: File to large ???
 

I hear what you say but I know exactly how I did it on the previous two occasions.:)

Re: File to large ???
 

OK mate maybe somehow you managed to do the impossible and break the FAT32 limitations

Just for point of reference as the forum seems to suggest the file is an archive that should be extracted how does the car install from it?

Re: File to large ???
 

Think I may have sorted it. I hadn’t updated my Download Manager App from last year.

I did this and as you correctly surmised it is now unzipping the file to usb stick.

Will see how it goes later.

Re: File to large ???
 

Sorted :)

Hopefully, thanks to everyone who took the trouble to answer.
