Why are the CBS Persist files so huge in size?
Firstly, these log files are created by the Microsoft windows resource checker. Usually, these files are not supposed to be larger than 50 MB. But what happens is after the updates, most of the CBS persist log files are decompressed due to certain reasons. They are initially in a zip format, highly compressed data. But due to some problems, they are decompressed, and thus, it increases the disk space massively.
As an example, you can see below that inside the zip. The file size is so huge.
But as a zip, it is only 15 MB
Thus, if the files are decompressed, the size takes up massive space in the disk, which is unimportant. But if it is in a zip file, you don’t have to do anything as it will only have the latest file.
