The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
0 bytes available on disk c means that disk c (system disk) has no space and the remaining space is 0 bytes.
The reason why the C drive is 0 bytes
Cause 1: The C drive space is full
First of all, when the C drive becomes 0 bytes, you should check the C drive memory to see if the C drive space is full.
If it is because the C drive has insufficient memory, you can clean up the C drive files and delete unnecessary files. When deleting C drive files, do not delete system files, otherwise it will cause computer system failure.
Note:
Prefetch: It is a pre-read folder, which is mainly used to store the pre-read information of files that have been accessed by the system; so it needs to be cleaned regularly. .
Backup: It is mainly used to back up files during the installation process of the installation software. When we install the software normally, there is no need to keep these backup files.
Temp: When the computer is running, it generally generates various useless temporary files.
Secondly, in addition to deleting redundant files to make space, you can also expand the C drive size.
Cause 2: Accidental deletion of system files
Accidental deletion of system files will also cause the C drive to become 0 bytes.
Here, you need to pay attention to which C drive files cannot be deleted.
The files in WINDOWS are important files required by the system. The PROGRAM FILES folder contains software files, such as: OFFICE (office software), WINDOWS MEDIA PLAYER (player), INTERNET EXPLORER (IE browser) , cannot be deleted.
Do not delete folders with SYSTEM in their names. These folders or files are related to system functions. Once deleted, they will cause the system to crash.
If you accidentally delete system files and cause the C drive to become 0 bytes, the easiest way is to reinstall the system to restore the computer to normal.
Extended knowledge: C drive file recovery
Since we mentioned reinstalling the system, let’s talk about the issue of C drive file recovery.
Because the C drive is a system drive, the situation is a little special.
If your computer’s hard drive is a solid-state drive, you must be prepared that the data cannot be recovered, because the characteristics of deleting files from the solid-state drive will make it difficult to recover the lost data.
If your computer hard drive is a mechanical disk, you can also try data recovery. You can use data recovery software or perform manual recovery. As long as the new system files do not overwrite the previous files, the C drive data can be recovered.
