This extension should provide an easy way to remove unused files inside of TYPO3 using FAL.
After installing ext:wv_file_cleanup a new BE module appears under "File".
Also the command controllers file:cleanup and file:emptyrecycler will be available.
Example of using the command controllers::
./typo3/cli_dispatch.phpsh extbase file:cleanup 1:/ --verbose
./typo3/cli_dispatch.phpsh extbase file:emptyrecycler 1:/ --verbose
The command controller can be setup in the scheduler as scheduler task.
You can configure an fileNameDenyPattern that holds a regular expression that is used to check the filename against. If the pattern matches the file is excluded from the cleanup and also not visible in het BE module.
Default value is /index.html/i so all index.html files are excluded and can be adjusted
in the extension configuration (see extension manager).
The value can also be overwritten in the command controller (and scheduler task).
To only match *.pdf files you can set the fileNameDenyPattern to /^(?!.*\b.pdf\b)/
Can be tested by executing this from CLI:
./typo3/cli_dispatch.phpsh extbase file:cleanup 1:/ --verbose --dry-run --file-deny-pattern='/^(?!.*\b.pdf\b)/'
