[SOLVED] Need Suggestions for File Permissions from Backup

[Gsparky2004]

UPDATE: There's no, easy way to change the permissions on every file without potentially hosing things up. But the problem is that I backed up the files to a Windows-based partition (NTFS), which is what caused the problem. Therefore, I'm switching the backup drive to "ext4" so that this won't happen in the future.
~~~~~~~~~~~~~~~~~~~~~~~~~
I'm running Linux Mint 21.1 Cinnamon. I managed to completely hose up my "home" directory the other day. I wound up reloading the OS and starting over. I'm slowly rebuilding my system. Here's the (possible) problem: As I copy files over from backup, I noted that they all have full permissions (read + write + execute for owner, group and other.) In other words, its as if I had run "chmod 777" on every file. I know that this can screw up certain encryption settings (SSH, for example). I was wondering if anyone had suggestions for other files that I should ensure do NOT have these full permissions? I'm already planning on running a small script that will turn off execution for each of my .txt files (getting annoyed with "Run or display?" each time I open one).
Thanks for any help.

Alternatively, you can eliminate that prompt in File Manager, Edit > Preferences > Behavior.

There's too many exceptions to any general rule to paste in a local example list so just to note: it's likely that the issue was caused by you backing up to a Microsoft filesystem type, i.e., one not supporting UNIX-credentials by which necessarily any non-standard such credentials are lost on restore.

That is: don't do that...

(*sighs in a very satisfied way when text files now just... open*)

Ah! That's probably precisely what happened. The backup drive was NTFS to make it possible to access files from the Windows partition.

don't do that...

Understood. The "access-from-Windows" is most certainly NOT worth this aggravation. Switching back to "ext4" now.
Thanks.
