Filesystem storage of BLOBs for Kotti.

Project Description

Filesystem storage of BLOBs for Kotti.

Find out more about BLOB storage in Kotti


You also need an option to tell Kotti to use the kotti_filestore add-on and to configure the location where the BLOBs will be stored on the filesystem. The line in your [app:main] (or [app:kotti], depending on how you setup Fanstatic) section could then look like this:

kotti.blobstore = kotti_filestore.filestore://%(here)s/filestore

The kotti_filestore.filestore part will cause Kotti to delegate the storage of BLOBs to this class. The %(here)s/filestore is an example configuration for the storage which will cause all BLOBs to be stored in a directory named filestore which will be automatically created in the same directory where your config file resides.


Currently a single configuration option exists. The absolute path of the directory where kotti_filestore stores the BLOBs can be specified with the path segment of the configuration URL.

To overcome limitations w.r.t. the maximum number of files within a directory on some filesystems, kotti_filestore generates a directory tree with a depth of 16, where each directory has a maximum of 256 children (either subdirectories or files).


  • kotti_filestore tries to be fully transaction aware.

    It does so by using repoze.filesafe for filesystem operation on files. Unfortunately repoze.filesafe doesn’t provide functions for directories. That’s why kotti_filestore may leave some empty directories on your filesystem. Files are removed properly on deletion of the corresponding content items though.

    As a workaround you are encouraged to setup a cronjob that scans for empty directories periodically and removes them.
