Why didn t the hard disk G drive put the files, how did it take up space?

Judging by your description, your G drive should be in NTFS format.

Any disk partition needs a specific file system to manage and control the files stored inside, and the reason why your G drive can be used normally is also because of the existence of this file system. The file system in the partition is also composed of a certain ** (the NTFS file system includes 16 metafiles such as $mft, which are invisible to the average user), and it also needs to occupy a certain amount of space, which is why your G drive has not created any files and folders at present, but you have a part of the space occupied.

？？？Do you mean that the free space on the hard drive is only?? If so, you can format it, and if you don't format it, it proves that this part is occupied by the system (virtual memory or system backup).

If you want to see what the bottom is, you have to use a disc to enter the Windows PE system to view it. Or open Winrar and view it with it.

You're talking about the capacity that is not given at the time of partitioning!

If that's the case, it's because of the loss of capacity due to different algorithms!

For example, when partitioning, you enter 10000M, which is 10G, then you can only see it under Windows!

Windows' algorithm is that 1024 is a base, which means that 1024M is equal to 1G, not 1000M is equal to 1G

Your problem is problematic, the space of the G drive, there is available, you still don't snicker? Hehe.

Causes: 1. Virus causes.

2. There are hidden partitions or encrypted files in the hard disk, so that the boot hard disk is invisible, but it occupies a lot of memory.

3. **All kinds of software, the cache of the software is automatically stored in the disk, but it is a hidden file, and the user can't see it. Check the hard disk with partitioning software, whether there is a hidden partition or something, if there is a hidden partition, it is invisible after the system starts.

4. Virtual memory.

Portable hard drivesThere are no more files in the show that there are hidden files in the occupied space. Here's how to view it.

1. First click to open the computer, and right-click the mobile hard disk in it.

2. Then click on the Properties option in the pop-up options.

3. Then in the properties dialog box, you can see that the empty disk is occupied by a large space.

4. At this time, open this disk and click on the tool option on it.

5. Then click on the folder in the pop-up options.

Options. <>

7. Finally, check the [Show hidden files, folders, and drives] under Hide protected operating system files. At this time, the hidden files in the disk will be displayed, and you can see the files on the empty disk, and you can delete the hidden files by unhiding them.

It takes up very few bytes of disk space!

1.The folder name or file name is the file allocation table that exists in the hard disk partition.

2.The file allocation table is used to record the location of the file.

3.Even a 0-byte file takes up 1 cluster of disk space. In a cluster of 512 bytes, a file is 1 byte, and it also occupies 1 cluster size in the disk, 512 bytes.

A file is 515 bytes and it will occupy 2 cluster sizes in the disk, which is 1024 bytes. (File storage is in a whole cluster, and one more byte goes into the second cluster).

The name of the empty folder will be written to the boot area, which is equivalent to a very small (negligible) hard drive, but the system will show that the folder occupies 0

If there are a large number of empty folders, such as 10,0000, it will also affect the browsing speed, but it is also very small.

The disadvantage of empty folders is mainly that it affects the user's management and browsing, but the space taken up is negligible!

Then you use partition software to check the hard disk, is there a hidden partition or something, if there is a hidden partition, it is invisible after the system starts. Some are made into two bootable systems, and the two partitions are shielded from each other, and some encrypted folders are invisible after encryption and are completely hidden in the system.

The problem of conversion, the manufacturer's standard capacity is never enough after partitioning the scale.

Your system also takes up space.
