, after a 45 K file has been changed several times, the file size becomes 49.5k → 58.5k → 68.5 K. I really don't know what to save to the file. Therefore, we have reason to doubt the effect of Access Database compression.I compiled a statistical system a year ago. It took about three months and was modified almost every day. It was compressed once in a few days. Finally, the size of the MDB file was 20 mb, even the MDE file has more than 8 Mb, so I am happy to think that I can design large files

If the program you want to run is not in the system-specified directory, the DOS operating system typically uses a path in the automatic batch file to automatically find the program, while in Windows you can increase the application path in a more secret way, rather than by setting up automatic batch processing.
