cover.jpg did not exist when this move operation was started

canpolat · 09-25-2017, 12:54 PM

Hi,

I started getting this exception when editting the title and author of some of the books in my library. I removed the books and restarted the Calibre, but still get the error. I don't think this is related to the books at all. Has anyone seen this? Any recommendations?

Code:

calibre, version 3.8.0

Actually, I can now confirm that I cannot perform any Title/Author modifications. Or, more accurately, the changes take place in the library, but the files are not moved.

canpolat · 09-25-2017, 01:16 PM

Installed 3.7.0 instead of 3.8.0 and the problem persists. This happens on a library that was transferred from a Linux PC (copied the library folder to an external HDD and then transferred it to this Windows machine). So, perhaps the problem is not directly related to Calibre. But since this is a relatively big database I don't want to import all the files from scratch. Any input would be appreciated.

Note: When Calibre said "The file u'blabla\\cover.jpg' did not exist when this move operation was started", the file was there and this is a book that is added on the Windows machine after the move.

What you can do is extract the cover and name it cover.jpg and put it in the eBook's directory.

Thank you for the response JSWolf. The problem is, the file is already there :/

JSWolf · 09-25-2017, 01:34 PM

Are you using some extended characters that could be causing the problem?

No. There are no visible special characters. I think the problem is due to the fact that this library folder is transferred from Linux to Windows (as explained in an earlier post). But I cannot find what may be the problem.

I see that a similar problem was reported by a user who was using a NAS: https://www.mobileread.com/forums/sh...d.php?t=195982

Try running Calibre in Administrator mode and see if it might be a permissions issue.

That was a good point and I was really excited, but it did not work. I still get the same error. It feels like the whole folder is haunted. I can add new books (drag & drop) so, somehow, Calibre can write into that folder. But when it comes to moving those created folders (even the ones created after the move), it cannot access the files. Peculiar.

JSWolf · 09-25-2017, 02:47 PM

I have two more ideas,

1. Try copying the entire library to a different folder and see if Windows can maybe fix whatever the problem is.

2. Click on the library icon in the toolbar and select Library maintenance and then Check library. If that works, select Yes from the Success requester. Then go from there based on what comes up.

2. Did run a "Check Library" and "Database Restore". The first one found and fixed some problems. But did not help with the problem.

1. The folder is very very big. I don't have enough disk space on this PC to duplicate the folder. I can try to move it back to a external HDD and move back, but that would take some hours.

My user has "Full Control" over the folder and its sub-folders. Perhaps I can try moving the folder back and forth to see anything changes.

Thank you for your support JSWolf. I think I will log off now. Will report back tomorrow...

@canpolat - some further ideas

Have a look in FAQ and see if anything might apply. Problems often manifest themselves in different ways. In particular these three items from FAQ - Miscellaneous

calibre is not starting on Windows?
calibre freezes/crashes occasionally?
Using the viewer or doing any conversions results in a permission denied error on Windows

Especially these suggestions:

run in safe mode - could be interference from a third party prog in startup etc
turn your AV off - could be it's preventing access

install the 32bit version, no need to uninstall the 64bit, it will use the same configuration and libraries - from the FAQ.

Quote:

On some 64 bit versions of Windows there are security software/settings that prevent 64-bit calibre from working properly. If you are using the 64-bit version of calibre try switching to the 32-bit version.

That should probably be "On some 64bit versions installations there are . . ." - I don't think it has ever been tied down to a specific version, it may be a specific patch.

Linux -> Windows has case issues if attempting to overwrite a previous Library

(this is usually needed going the other way)
Quality Check plugin: Fix: Check and rename Book Paths

That error indicates either that some other process is writing to the calibre library folders at the same time as calibre, or the filesystem you have the library on is broken. Make sure the filesystem is a local disk formatted with NTFS.

And if you want to move a library from one OS to another robustly you can use the import/export tool to do it. https://manual.calibre-ebook.com/faq...ter-to-another
