Hello. Thanks for reading my topic.
Here is Lubuntu 24.04.3 kernel 6.14.
BTRFS partition was mounted enabling compression in fstab ( compress-force=zlib:9 ).
Double Commander doing file operations in that BTRFS partition not does file compression for any file, but if using other file manager for example PCMANFM-QT and others softwares ( text editors ) is done file compression.
Using in terminal compsize show the compression used in directories.
I have done tests using Double commander in paths below, starting in root and apparmor disabled having the same results :
/home/username/doublecmd
/opt/doublecmd
/usr/bin using an symbolic link
/usr/local/bin
Perhaps Double Commander are using an internal own file operation code or for security the OS not are allowing file compression if using it.
Have any way to fix it ? OS have any configuration to allow that software to do any file operation without restrictions ?
Have a nice week.
