Hello.
It would seem like a simple task: transfer one (or several) files from one computer to another, after writing them to a USB flash drive. As a rule, there are no problems with small (up to 4000 MB) files, but what about other (large) files that sometimes do not fit on a USB flash drive (and if they should fit, then for some reason an error appears when copying)?
In this short article I will give some tips to help you write files larger than 4 GB to a USB flash drive. So...
Why does an error appear when copying a file larger than 4 GB to a USB flash drive
Perhaps this is the first question from which to start the article. The fact is that many flash drives come with the file system by default Fat32. And after buying a flash drive, most users do not change this file system (those. remains FAT32) But the file system FAT32 does not support files larger than 4 GB - therefore, you begin to write the file to the USB flash drive, and when it reaches the 4 GB threshold, a write error appears.
To eliminate such a mistake (or to circumvent it), there are several ways to do this:
- record not one large file - but a lot of small ones (ie split the file into "pieces". By the way, this method is suitable if you need to transfer a file whose size is larger than the size of your flash drive!);
- format the USB flash drive to another file system (for example, to NTFS. Attention! Formatting deletes all data from the media );
- convert without loss of data FAT32 to the NTFS file system.
I will consider each method in more detail.
1) How to split one large file into several small ones and write them to a USB flash drive
This method is good for its versatility and simplicity: you do not need to do backup files from a flash drive (for example, to format it), you do not need to convert anything or where (do not waste time on these operations). In addition, this method is perfect if your flash drive is smaller than the file you need to transfer (you just have to flip pieces of the file 2 times, or use a second flash drive).
One of the most popular programs, which often replaces the explorer. It allows you to perform all the most necessary operations on files: renaming (including mass), compressing to archives, unpacking, splitting files, working with FTP, etc. In general, one of those programs - which is recommended to be mandatory on a PC.
To split a file in Total Commander: choose with the mouse desired file, and then go to the menu: " File / split file "(screenshot below).
Split file
Next, you need to enter the size of the parts in MB into which the file will be split. The most popular sizes (for example, for burning to a CD) are already present in the program. In general, enter the desired size: for example, 3900 MB.
And then the program will split the file into parts, and you just have to save all (or several of them) to a USB flash drive and transfer it to another PC (laptop). In principle, the task has been completed.
By the way, the screenshot above shows the source file, and in the red frame the files that turned out when the source file was split into several parts.
To open the source file on another computer (where you will transfer these files), you need to do the reverse procedure: i.e. assemble the file. First, transfer all the pieces of the broken source file, and then open Total Commander, select the first file ( with type 001, see screen above) and go to the menu " File / Build File ". Actually, all that remains is to specify the folder where the file will be assembled and wait a while ...
2) How to format a USB flash drive to the NTFS file system
The formatting operation will help if you are trying to write a file of more than 4 GB to a USB flash drive whose file system is FAT32 (i.e. does not support such large files) Consider the step-by-step operation.
Attention! When formatting a flash drive on it, all files will be deleted. Before this operation, make a backup copy of all important data that is on it.
1) First you need to go to "My computer" (or "This computer", depending on the version of Windows).
3) Right-click on the USB flash drive and select the " Format"(see screenshot below).
After a few seconds (usually), the operation will be completed and it will be possible to continue working with the USB flash drive (including writing to it larger files than before).
3) How to convert FAT32 file system to NTFS
In general, despite the fact that the operation of an envelope from FAT32 to NTFS should take place without data loss, I recommend that you save all important documents to a separate medium ( of personal experience : doing this operation dozens of times, one of them ended with the fact that part of the folders with Russian names lost their names, becoming hieroglyphs. Those. Encoding error occurred).
This operation will also take some time, therefore, in my opinion, for a flash drive, the preferred option is formatting ( with a preliminary copy of important data. About this a little higher in the article).
So, to make the conversion, you need:
