When are cached KurocoFiles cleared?
Whenever you upload or delete a file in the KurocoFiles, the corresponding file in the CDN cache folder is cleared. The cache clearing usually takes less than 1 second, although it may take up to 10 seconds in some cases.
Note
Folders may not be properly cleared from the cache if the folder name contains URL-encoded characters that are not half-width alphanumeric. Therefore, please avoid using any such characters (e.g., Japanese, Korean, Chinese scripts) in your folder names.
