Attachment File Size

Hi, perhaps it is just me but I personally would find it very useful if Zotero could indicate the file size of the attachment when I select on say an attached PDF file. I don't know if this is possible or easy to implement, but it seems to make sense to add 'Size' to the list of information Zotero currently displays for the attached files: Filename, Page, Modified, and Indexed.
  • I could have sworn there used to be a column that would give some indication of this for both whole items and attached files...
  • +1 on that!!!
    I'm just using Zotero in the free version with 100mb of storage and I frequently run out of storage..
    I would very much appreciate a column where I can show the size of entries..
    Especially as some Website snaptshots use much space (and are not really important).

    So Please! Add this feature..
  • I've created an issue for this.
  • Yes, please let us see the size of files so that we can better manage our use of storage.
  • +1

    I would like to purge old attachments that are no longer needed but take gigabytes of space - but do not know how an efficient way to find the relevant ones.
  • Related to the above discussion, I would like to rename large pdf attachments with Zotfile and move them to an external hard disk (i.e. convert a stored copy attachment to a linked attachment) rather than deleting them altogether.

    I am currently able to pinpoint large attachments using Finder on Mac:

    The Zotero item in question can then be located via the file-name of the attachment - if I have previously renamed that file from its parent metadata.

    I am guessing that the names of the folders under the 'Storage' directory refer to a unique key generated for each Zotero record.

    Could there be a way, say to do a bulk search for all records using the list of unique key generated by Finder, something similar to the magic wand function (http://uploads.im/4UY3e.png) whereby we can feed in multiple ISBNs at one go, so that we don't have do the renaming one at a time?

    If feeding in this list: K94N28DG, ATTXCKNB... can give us the relevant search results, then this can be done: http://uploads.im/s8jwg.png

    This is my self-devised way of relocating large attachments.

    I wonder if the above features or something similar can be implemented on the new version of Zotero to ease this task?

    Thank you!

    I thought a "file size" column addition would be implemented by now, but I think it is not?
  • came here looking for a quick way to find large files. In the absence of a built in tool, I cobbled together something in shell:

    # usage of all items (by folder)
    du -hcs ~/Zotero/storage/*/ |sort -hr > /tmp/zot_diskusage.txt

    # top usage, assume pdf. file name will have item title
    head /tmp/zot_diskusage.txt | grep -v 'total'|cut -f 2|while read f; do du -h $f/*pdf; done
  • Same here, wondering if there is a problem downloading larger files on my e-ink device, but cannot easily see the size of the attachement not downloaded. Can of course browse on a computer to the local storage and compare, but it seems like a quite trivial thing to add. +1 on file size, 13 years after request ;)
  • For Zotero desktop, the Attachment Scanner plugin can add columns for number of attachments and size of attachments. Although the latter is apparently slow, as it must be read from disk. I only use the attachment number.
