What should I do if the file is particularly large after ps is drawn?

You can shrink a file by changing its resolution or size.

The specific steps are as follows:

1. Changing the resolution or size of the file can reduce the size of the file. You can modify the image size panel by pressing CTRL+ALT+I.

2. Merging layers, deleting unnecessary layers in the production process, and merging most unnecessary layers can also reduce the file size.

3. When saving, closing all layers can also reduce the file size.

4. When saving, you can also change the size by saving as a web format.

5. Change the storage size of the file to meet the operating requirements. Otherwise, it will not affect the clarity of the picture.
