I don't know either...
I'm not doing anything special: 
1) I am used to putting my emails into directories and subdirectories
within "Mozilla Thunderbird". 
2) I want to export that structure - hierarchy of directories - along
with the emails it contains into a format compatible with "Claws Mail".
3) And finally, I want to import all that into "Claws Mail". 
And there is no reason why any file or directory should be corrupted.

..............................
SOMETHING WHICH WORKS PROPERLY
..............................
Suppose I have a simple folder "f" containing emails in "Mozilla
Thunderbird". 
If I chose: "Tools" -> "ImportExportTools" -> "Export folder", I get a
file "f" as a result. 
Prior to this, in "Tools" -> "ImportExportTools" -> "Options" ->
"Export directories", I checked the "Export folders as MBOX file" check
box. 
In "Claws Mail", if I choose: "File" -> "Import mbox file..." and
select "f": I recover my emails properly.

..............................
SOMETHING WHICH DOESN'T WORK
..............................
Now, suppose I have a folfer "f" containing two subfolders "f1" and
"f2" which in turn contain emails ("m1" to "m5"):

f
    f1
       m1
       m2
    f2
       m3
       m4
       m5

if I do the same thing as above and if I choose:
a) "Export folder with subfolders (simple)", I get three files "f",
"f1" and "f2". 
"f" size is 0. 
"f1" and "f2" have a non-zero size. 
In "Claws Mail", when I choose "File" -> "Import mbox file..." and
select "f". It fails.

b) "Export folder with subfolders (with structure)", I get
a file "f" and a folder "f.sdb".
Again "f" size is zero. 
"f.sdb" contains to files "f1" and "f2" with non-zero size. 
In "Claws Mail", if I choose, "File" -> "Import mbox file..." and
select "f". It fails again.

I have no filters...

That could solve my problem?

So, I'm still wondering if I can import a hierarchy of folders,
subfolders and emails coming from "Mozilla Thunderbird" into "Claws
Mail" and how?

Thank you in advance for helping.
