Trash Bin not working

[Nguyen Quoc Khanh]

I have just tested the new Trash Bin (Calibre 6.16).

Right-clicking on the TrashBin icon and selecting the "Restore recently deleted..." results in an error:

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\...\\.caltrash\\b\\8349\\metadata.opf'

I guess since this is Windows, the double back-slash (\\) is the reason.

I manually browse to the .caltrash\b folder, the file is there.

Is there any "empty trash bin" option too?

[Kovid Goyal (kovid)]

Works for me. the doubel back slash is simply how backslashes are
encoded in python. Post the full error message and the full path to the
library.

[Kovid Goyal (kovid)]

And you are saying the file

C:\Users\Mike\OneDrive - angels2285\Calibre\.caltrash\b\8349\metadata.opf

exists? If so that error makes no sense. Does it happen if you try with
a library not in OneDrive?

[Nguyen Quoc Khanh (quockhanh77)]

Ah, the metadata.opf file is NOT there. The 8349 folder includes only the epub and the cover.jpg.

I have to run now, if testing with another library is needed, I will do it later.

[Nguyen Quoc Khanh (quockhanh77)]

Dear Kovid,

I understand why now. If the metadata.opf file doesn't exist before the book is deleted, then that error will happen. Location of the library is not relevant.

[Kovid Goyal (kovid)]

No the metadata.opf file is created when deleting so it should never not
exist. However, looking at the code there is a case where that creation
can fail, which I will fix.

[Kovid Goyal (kovid)]

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
