A script that converts any file into a batch.
The advantage of Base64 encoding is that the data size is compressed (compared with bin2str). The disadvantage is that it increases the processing time and script complexity.
Because the efficiency bottleneck lies in the process of generating vbs in bat, it is still possible.
Writing files using ADODB. Recordset is much better than debugging.
Most of the tasks are done by scripts. batch processing only uses echo to generate scripts.
The advantage of echo version is that the file is uploaded after all copies and pasted to the cmd shell.

The usage is simple. It is just a parameter-the full path of the file to be converted.
You can also drag and drop a file to the vbs icon.
