Answered FTP saving problems

Hi there.
Triing to save my site by FTP with FileZilla and getting an error. 5 files cannot be copied. They all are located in /core/cache/mgr/min and have very long names. Other files in this directory (which also have long names) are being copied just fine. The server says: file transfering failed, impossible to begin transfer. The rights (permissions) of files are the same as the files that are copied normally.
FZ version: 3.14
modx version: 2.4

What are these files? Are they important?

The entire core/cache can be skipped in any backup or copying arrangement. MODX will regenerate them as needed when it runs.

Thank you. What about the cause of the problem? Any ideas why some files are copied normally and the others are not?

No. I don't even have those files in any of my sites that I've look at, localhost, MODX Cloud or SkyToaster, so I have no idea what they are or where they come from.

Ok, here's a reference that explains what they are, I always have minifyJS and minfyCSS turned off. https://forums.modx.com/thread/88032/minify-cache-not-working

Shocking the number of sites with web space file indexing turned on! A google search for core/cache/mgr/min was quite interesting.

I'm new to modx. How to turn them off?
P.S. And why are they turned on by default if not needed at all?

That was somebody's bright idea, that really isn't such a good idea after all. You can turn them off in the System Settings (compress_css and compress_js).

The latest version of MODX also has a checkbox in the setup that allows you to have it on or off by default on installation.

I think Susan meant the compress_js and compress_css System Settings.

Go to System (gear icon in later versions) -> System Settings. Put compress in the search box at the upper right and press Enter.

Double click on the values and change them from 'Yes' to 'No'.
