What is a split-volume compressed file?

When transmitting or storing data, volume compression file technology can help us solve the problem of excessively large files and inconvenient transmission. This article will deeply explore the principles, methods and application scenarios of volume compression to help everyone master this practical technology. PHP editor Strawberry specially compiled the following content:

1. What is a volume compressed file?

Many people have encountered such a situation. Because the file is too large, network transmission fails after compression, or there is insufficient storage space.

In order to solve this problem, we can compress the file into several compressed packages of the same size. These small compressed packages are called volume compressed files. When all sub-volume files are complete and formatted, they can be processed as a complete compressed file.

2. How to create volume compressed files?

We need to use a decompression tool with volume compression function to create volumes, such as WinRAR, 7-ZIP, etc.

Taking WinRAR as an example, first select the file or folder that needs to be compressed, right-click the mouse and select [Add to compressed file] in the WinRAR list.

After the dialog box pops up, click the [General] interface, and then select [Compressed file format] as needed, such as RAR or ZIP format; then click the [Split into volumes, size] drop-down list to select the size of each volume. , or customize the size, enter data in the blank column, such as 10M;

If you need to keep the volume file confidential, you can click [Set Password] to set the password for opening the volume file.

Finally click [OK] to create the compressed volume file.

After the creation is completed, you can see that the file is compressed into several compressed packages named in a specific format, that is, volume compressed files.

WinRAR, 7-ZIP and other decompression tools can decompress volume compressed files. We can choose the corresponding one according to the format of the volume file. Tool of.

Before decompressing, you need to find all the compressed files in volumes and put them in the same folder. You must also keep the initial format of the file names in the volumes and cannot make any changes, otherwise it will prompt that the decompression failed.

Then, select the first volume to decompress, and all volumes can be decompressed together.

If a password is set for the volume file, when decompressing, the first volume will also be decompressed, and then enter

in the pop-up dialog box.

The originally set password can be used to decompress all volume files.

Of course, if you forget your password, you will not be able to open or decompress the volume compressed file, because the decompression tool does not have a "forgot password" option. In this case, we need to use other tools to solve the problem.

The Zip and RAR tools used by the editor in the picture below can help us retrieve the password of the compressed file in separate volumes.

The ZIP tool supports volume compressed files in ZIP and 7Z formats, and the RAR tool supports volume compressed files in RAR format.
