WinRAR is a very familiar compression tool. In fact, you can also merge folders in batches, and the method is not complicated. First, add the folders to be merged into a temporary compressed package one by one, and then release them with WinRAR. Note that when releasing, you need to switch to the Advanced tab. The default file path setting is Full Path to Unzip. Please reset it to "pathless decompression" before releasing the file.

The files in the folder are released to a directory.

The biggest advantage of using WinRAR is convenience. After all, WinRAR can be seen everywhere. However, its shortcomings are also obvious, and the processing links are complicated, so it is necessary to pack them in advance and release them afterwards; The processing speed is not optimistic. WinRAR is not an ideal choice when there are many folders to deal with. The processing of files with the same name lacks adaptability, and only one file can be kept when encountering files with the same name.
