Caution
- If you are sharing files with other users, do not use J-Storage as a permanent storage for the original files, and ask them to copy the necessary files to another storage location (which may cause confusion if the sharing settings are removed).
- There is no data retention period, but please delete or unshare unnecessary data as soon as possible.
- The file size that can be uploaded or downloaded at one time is up to 30 GB (operationally confirmed).
- Please be careful when sharing the file name to other users, as some devices do not distinguish between upper- and lower-case characters (synchronization error occurs).
Application installation
By installing a dedicated application on a PC or smartphone, in addition to the functions available on the Web browser, synchronization between folders in the local storage and folders in the Jstorage-2018 server becomes possible. You can download it from the dedicated application Nextcloud website or Jstorage-2018 settings.
