How to use a USB stick in Windows

If you intend to make the best use of your USB drive in windows, read the following paragraphs in which, in which I will provide you with clear indications on the file systems supported by the operating system Microsoft (which determines how the data is organized in the key), on the procedure to format the keys and the steps to follow to access the data it contains.

Supported file systems

The operating system windows offers native support for the most common and used File System. At the time of write In this guide, it is possible to read and format USB memory sticks equipped with one of the file systems listed below.

  • FAT: (or FAT16): This is an outdated and no longer used file system, with numerous problems related to file management and preservation.
  • FAT32 - the most widespread file system of all time, offering the highest degree of compatibility with other devices and operating systems. It cannot handle files larger than 4GB and it does not support partitions larger than 32GB. Furthermore, it is significantly subject to fragmentation.
  • exFAT (or Extended FAT) - Successor to FAT32, removes 4GB per file and 32GB per single partition limit. It is compatible with many devices, although less in number than FAT32, and is less subject to fragmentation.
  • NTFS - is the default Windows file system. It removes all the limitations of FAT and offers a host of advantages in organizing and managing files, but relative support is not guaranteed on all operating systems. It is subject to fragmentation, but to a lesser extent than FAT.

Format the stick

Format a USB memory in the windows, it is literally obvious. First, insert the unit into the PC, connecting it to one of its free ports. Then open the File Browser by clicking on the icon yellow folder placed on the taskbar and click on the icon This PC / Pc, located in the left area of ​​the window that opens.

At this point, find the icon of USB in the section Devices and units (you may need to click the arrow corresponding to the section title, if it is closed), right click on the stick name and choose the item Format … from the context menu.

Now, use the following window to configure the format parameters: File System, allocation unit size (if you don't know what it is, leave this field unchanged) ed volume label (the name to be assigned to the stick).

Finally, it acts on the box Quick format to define how to overwrite data: if you enable it, formatting will take a few seconds, but previously saved data may be restored using special programs.

However, by disabling quick formatting, the data will be overwritten with a string of 0 and recovery will become much more complex; however, slow formatting can be time consuming.

Anyway, once you have defined the most suitable options for you, click on the button starts and, aware that this operation will erase all data on the stick press the button good, to continue. Then wait for the message to finish formatting.

For more information on the procedure just illustrated, you can refer to my guide on how to format a USB stick, in which I covered the subject in great detail.

Manage files on the stick

If formatting a key was easy, managing the files on it is even more! Just insert the disk into the PC, wait for the screen to appear Automatic playback and choose the most suitable operation for your case: view photos, play videos or music, start the installation files or open the folder to explore the files.

If the AutoPlay window does not appear, you can easily access the data on the USB drive by starting the File Browser Windows, going to the section This PC / Pc (left) and double-clicking the icon of the USB memory you just inserted.

Otherwise, there's not much more to say: you can easily move files / folders from one point on the device to the hard drive (and vice versa) by dragging them to the folder of your choice, or access the operations available in each by right-clicking on your icon

How to use a USB stick on Mac

On the use of USB drives in Mac, things are not very different from what has already been seen for Windows: macOS, in fact, integrates the necessary functions to format and manage the files saved in a storage device of this type.

Below, I'll give you an overview of the file systems supported by Mac, then illustrate the steps you need to take to format a key and explore the data it contains.

Please note that some Macs may not have a standard USB (USB-A) port, but only a Thunderbolt (USB-C) port - in this case, you will need a special adapter, like the ones shown below.

Supported file systems

At the time of writing this guide, macOS offers full support for the following file systems.

  • APFS - this is the system Mac files default, with technical characteristics aimed at obtaining the best possible performance when reading / writing data. Despite its many advantages, APFS is not supported outside of the Apple world - so be sure to only use it if the USB stick is designed for Mac only.
  • MacOS expanded daily (HFS +): This is the "predecessor" file system of APFS, currently supported by even older Macs. Again, Apple's out-of-world compatibility is very poor.
  • MS-DOS grease (FAT32) - as already seen in the Windows section, it is the most widespread file system, which has limits on the size of a single file (4 GB) and a single partition (32 GB). Use it if you intend to use the device on multiple devices with different operating systems.
  • exFAT - is the successor to MS-DOS FAT, which bypasses the size and file size limit, but finds slightly less support than its predecessor.

The file system NTFS instead, it is natively compatible with macOS in read only ; To add the ability to write data to USB drives of this type, or to format it using this file system, it is necessary to resort to some specific drivers, as I explained in my guide on how to format NTFS with Mac.

Format the stick

If you need to format the USB memory, you can use the Disk utility macOS - The tool for managing keys, disks, SSDs and other storage media, installed "standard" on Mac.

To use it, call it from the folder more la Launchpad (the icon in the form of rocket placed in spring ) and after connecting the USB flash drive to the Mac, select its name in the left sidebar, then click the button initialize, placed at the top.

At this point, indicate the file system you plan to use, choose it from the menu format ; tax GUID partition map how scheme, if you have chosen to use an Apple file system (APFS / HFS +), or Master boot record for all others, indicates the name to be assigned to the key in the appropriate field and when done click the buttons good y initialize, to start formatting the drive.

For further clarification on the steps just illustrated, you can refer to my guide on how to format a USB stick on Mac.

note : If desired, you can adjust the number of overwrite to be performed during the format phase, to make any data recovery more difficult (however, slowing down the whole process). To do this, click on the button Security options … and use the displayed cursor to define the most suitable option for you.

Manage files on the stick

Open a USB stick on macOS It is very simple: in general, all you have to do is connect the peripheral to the appropriate port on the PC and wait for the operating system to recognize it and mount it on the desk. When this happens, just double click on the drive icon to open the discoverer and access its contents.

Alternatively, you can access the key files by opening the discoverer directly from the Dock (by clicking the icon in the form of smiley face located in it) and clicking USB drive namelocated under the box devices (in the left sidebar).

File management is almost identical to that provided for all other Mac folders: you can move, copy and paste files to and from the device, create new folders, create archives, etc., using the context menu provided by macOS ( it can be called by right-clicking on the icon of the file or folder of interest).

How to use a USB stick as RAM

Would you like to know if it is possible? use a USB stick as RAM ? The answer is yes.

All operating systems windows currently supports built-in functionality ReadyBoost : In practice, it allows using a USB memory as if it were part of the RAM memory, to speed up the exchange of data between the hard drives and the processor.

This system can partially improve performance on quite old-fashioned machines (equipped with less than 2 GB of RAM and animated by mechanical disks), however, on more modern PCs, ReadyBoost and, in general, the use of USB sticks as RAM: no it brings many improvements, especially if you are using an SSD type main memory (in this case ReadyBoost cannot be activated).

In addition, in order for this system to be as useful as possible, the USB memory must have a good access speed that's why I advise you to use a stick USB 3.0 (the one with the internal blue connector), connected to a port of the same type. Ideally, the size of the stick that will be dedicated to RAM should be double physical memory installed in the system.

As they say It is perfectly clear on the concept, but would you like to try using your USB stick as RAM and trying to speed up the PC a bit? Ok, no problem. To begin, insert the USB device into your PC and format in exFAT (to allow allocation of files larger than 4GB), using the instructions I have provided above.

Then open the File Explorer / Windows Explorer Windows (the icon of the yellow folder located on the taskbar), click the icon This PC / Pc Located on the left side of the window, right-click the icon of the USB memory you want to use and click the button property.

At this point, go to the card ReadyBoost, put the check mark next to the article Dedicate the device to ReadyBoost / Use the device and use the cursor below to choose the amount of virtual RAM you want to add. When you're done, click the buttons. apply y good and wait for the configuration to complete.

How to use a USB memory as a hard drive

The need to use a USB memory as a hard drive It could arise, for example, from the need to use the key exactly as if it were a hard disk, with the possibility of creating and modifying partitions, deleting them, managing them, etc. These operations, as far as USB drives are concerned, are not immediately accessible from the operating system menus, which, on the other hand, occurs with disks.

However, today, the use of software that can "fool" the operating system into managing a USB memory like a hard disk is a » risky operation which, for my part, I advise against carrying out: programs of this type could not only damage the usb stick, making it unusable, but it could cause it operating system problems, even seriously.

For this reason, instead of resorting to such dangerous and outdated solutions today, you could use special programs that can operate on USB memory partitions and also install complete operating systems on them.

Next, place the check mark next to the item. I agree, to accept the conditions of use of the program, click on the button siguiente three times in a row, then up yes y search to finish the installation procedure and start the software.

Once in the main screen of the program, connect the USB memory that you want to use as password to the PC, click on the button good attached to the warning window that appears, and then choose the key you just inserted from the drop-down menu Selected unit.
