Directory level setting?

[HarikalarKutusu]

I check the compact.exe documentation:
https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/compact

It states:

/c  |  Compresses the specified directory or file. Directories are marked so any files added afterwards are compressed, unless the /EXE parameter is specified.

So, if you compact a directory, anything added into it will also automatically compacted at the OS level. On the other hand, we need to re-compact again and again.

Am I missing something?

Correct, but as it says that only works if you exclusively use the /c flag and nothing else. Thats the same as using the "compress this folder" option when you open a folder's properties in File Explorer.

Those methods are not as performant as the XPRESS and LZX algorithms used here

To get those algorithms in the compact function, you specify /c /EXE:XPRESS4K but those aren't automatically monitored/compressed by Windows.

Oh, I didn't know compact.exe had connection to the old algorithm. Thanks.
