Yes I should have provided more detail. Sorry about that.
The archive is created on Slackware Linux 64, with 64-bit Rar 5.11. I carry it around on my USB stick so encryption is important.
The command is as follows:
rar u -ma5 -as -ep2 -htb -m4 -md64m -ms -p -qo -r -rr5p \
/data/private.rar @/data/files.lst
private.rar is the archive created and files.lst the list of files to be included.
Here is a description of the switches for convenience:
u - add and update new files to archive;
-ma5 - use the new RAR5 format;
-as - synchronize archive so that any files not listed in file
list are deleted from archive;
-ep2 - store full paths
-htb - use Blake2sp file checksums;
-m4 - compression level = good;
-md64m - dictionary size = 64M;
-ms - do not compress already-compressed files;
-p - encrypt with password;
-qo - add quick-open information;
-r - recurse through subfolders;
-rr5p - 5% recovery record;
Here is a sample path with the problem I describe:
D:\private.rar\data\office\ms-service-packs\office-{2000,2003,2007,2010,xp}
In Linux the path is:
/data/office/ms-service-packs/office-2000
/data/office/ms-service-packs/office-2003, etc.
In MC "private.rar" opens properly, as do "data", "office", and "ms-service-packs", but the five subfolders inside ms-service-packs do not open properly. Instead, they throw me out to the default system file manager, where the contents of these subfolders are not displayed.
Furthermore, the icon overlay for these subfolders is different. Attached is a screenshot showing this icon overlay and the subfolders which do not open.
The funny thing is, when I mimic the creation of this archive in Windows using WinRAR I have no problem opening it in MC.
