--- title: "Uloz.to" description: "Rclone docs for Uloz.to" versionIntroduced: "v1.66" --- # {{< icon "fa fa-box-archive" >}} Uloz.to Paths are specified as `remote:path` Paths may be as deep as required, e.g. `remote:directory/subdirectory`. The initial setup for Box involves filling in the user credentials. `rclone config` walks you through it. ## Configuration Here is an example of how to make a remote called `remote`. First run: rclone config This will guide you through an interactive setup process: ``` No remotes found, make a new one? n) New remote s) Set configuration password q) Quit config n/s/q> n name> remote Type of storage to configure. Choose a number from below, or type in your own value [snip] XX / Uloz.to \ "ulozto" [snip] Storage> ulozto Option app_token. The application token identifying the app. An app API key can be either found in the API doc https://uloz.to/upload-resumable-api-beta or obtained from customer service. Enter a value. Press Enter to leave empty. app_token> token_value Option username. The username of the principal to operate as. Enter a value. Press Enter to leave empty. username> user Option password. The password for the user. Enter a value. Press Enter to leave empty. password> secretPassword Edit advanced config? y) Yes n) No (default) y/n> n Keep this "remote" remote? y) Yes this is OK (default) e) Edit this remote d) Delete this remote y/e/d> y ``` Once configured you can then use `rclone` like this, List folders in root level folder: rclone lsd remote: List all the files in your root folder: rclone ls remote: To copy a local folder to a Uloz.to folder called backup: rclone copy /home/source remote:backup ### User credentials The only reliable method is to authenticate the user using username and password. Uloz.to offers anb API key as well, but it's reserved for the use of Uloz.to's in-house application and using it in different circumstances is unreliable. ### Modification times and hashes Uloz.to doesn't allow the user to set a custom modification time, or retrieve the hashes after upload. As a result, the integration uses a free form field the API provides to encode client-provided timestamps and hashes. Timestamps are stored with microsecond precision. A server calculated MD5 hash of the file is verified upon upload. Afterwards, the backend only serves the client-side calculated hashes. Hashes can also be retrieved upon creating a file download link, but it's impractical for `list`-like use cases. ### Restricted filename characters In addition to the [default restricted characters set](/overview/#restricted-characters) the following characters are also replaced: | Character | Value | Replacement | | --------- |:-----:|:-----------:| | \ | 0x5C | ＼ | Invalid UTF-8 bytes will also be [replaced](/overview/#invalid-utf8), as they can't be used in JSON strings. ### Transfers All files are currently uploaded using a single HTTP request, so for uploading large files a stable connection is necessary. Rclone will upload up to `--transfers` chunks at the same time (shared among all uploads). ### Deleting files By default, files are moved to the recycle bin whereas folders are deleted immediately. Trashed files are permanently deleted after 30 days in the recycle bin. Emptying the trash is currently not implemented in rclone. ### Root folder ID You can set the `root_folder_slug` for rclone. This is the folder (identified by its `Folder slug`) that rclone considers to be the root of your Uloz.to drive. Normally you will leave this blank and rclone will determine the correct root to use itself. However you can set this to restrict rclone to a specific folder hierarchy. In order to do this you will have to find the `Folder slug` of the folder you wish to use as root. This will be the last segment of the URL when you open the relevant folder in the Box web interface. For example, for exploring a folder with URL `https://uloz.to/fm/my-files/foobar`, `foobar` should be used as the root slug. `root_folder_slug` can be used alongside a specific path in the remote path. For example, if your remote's `root_folder_slug` corresponds to `/foo/bar`, `remote:baz/qux` will refer to `ABSOLUTE_ULOZTO_ROOT/foo/bar/baz/qux`. {{< rem autogenerated options start" - DO NOT EDIT - instead edit fs.RegInfo in backend/ulozto/ulozto.go then run make backenddocs" >}} ### Standard options Here are the Standard options specific to ulozto (Uloz.to). #### --ulozto-app-token The application token identifying the app. An app API key can be either found in the API doc https://uloz.to/upload-resumable-api-beta or obtained from customer service. Properties: - Config: app_token - Env Var: RCLONE_ULOZTO_APP_TOKEN - Type: string - Required: false #### --ulozto-username The username of the principal to operate as. Properties: - Config: username - Env Var: RCLONE_ULOZTO_USERNAME - Type: string - Required: false #### --ulozto-password The password for the user. Properties: - Config: password - Env Var: RCLONE_ULOZTO_PASSWORD - Type: string - Required: false ### Advanced options Here are the Advanced options specific to ulozto (Uloz.to). #### --ulozto-root-folder-slug If set, rclone will use this folder as the root folder for all operations. For example, if the slug identifies 'foo/bar/', 'ulozto:baz' is equivalent to 'ulozto:foo/bar/baz' without any root slug set. Properties: - Config: root_folder_slug - Env Var: RCLONE_ULOZTO_ROOT_FOLDER_SLUG - Type: string - Required: false #### --ulozto-list-page-size The size of a single page for list commands. 1-500 Properties: - Config: list_page_size - Env Var: RCLONE_ULOZTO_LIST_PAGE_SIZE - Type: int - Default: 500 #### --ulozto-encoding The encoding for the backend. See the [encoding section in the overview](/overview/#encoding) for more info. Properties: - Config: encoding - Env Var: RCLONE_ULOZTO_ENCODING - Type: Encoding - Default: Slash,BackSlash,Del,Ctl,InvalidUtf8,Dot {{< rem autogenerated options stop >}} ## Limitations Uloz.to file names can't have the `\` character in. rclone maps this to and from an identical looking unicode equivalent `＼` (U+FF3C Fullwidth Reverse Solidus). Uloz.to only supports filenames up to 255 characters in length. Uloz.to rate limits access to the API, but exact details are undisclosed. Practical testing reveals that hitting the rate limit during normal use is very rare, although not impossible with higher number of concurrently uploaded files. `rclone about` is not supported by the Uloz.to backend. Although there's an endpoint to retrieve the information for the UI, it's not exposed in the API. Backends without this capability cannot determine free space for an rclone mount or use policy `mfs` (most free space) as a member of an rclone union remote. See [List of backends that do not support rclone about](https://rclone.org/overview/#optional-features) and [rclone about](https://rclone.org/commands/rclone_about/)
