# Bucket File can be grouped into **Bucket**. > Bucket are created dynamically when you upload a new file. ### From API In the example below, the bucket \`my-super-bucket\` will be created. ```typescript const resultPreSignUrl = await getPreSignedUrlApplicationFile( { applicationId: "my-application-id" }, { type: PreSignUrlType.UPLOAD, fileName: fileToUpload.name, bucket: `my-super-bucket` }, ); ``` You can manage buckets using **deleteBucketApplicationFile, renameBucketApplicationFile, and updateBucketApplicationFile** ```typescript // It will delete bucket `my-bucket` and sub buckets `my-bucket/sub-bucket` and corresponding files await deleteBucketApplicationFile( { applicationId: "my-application-id" }, { bucket: `my-bucket` }, ); ``` ```typescript // It will rename bucket // `my-bucket` -> `new-bucket` // `my-bucket/sub-bucket` -> `new-bucket/sub-bucket/` await renameBucketApplicationFile( { applicationId: "my-application-id" }, { bucket: `my-bucket`, newBucket: `new-bucket` }, ); ```

// It will update bucket for corresponding file
// Before: file.bucket => `old-bucket/sub-bucket`
// After: file.bucket => `my-bucket/`
await updateBucketApplicationFile(
  { applicationId: "my-application-id" },
  { bucket: `my-bucket`, applicationFileIds: ["file-id"] },
);

### Client App #### Create new bucket You can create a new bucket by moving to a specific bucket path and upload a new file.

#### Rename bucket You can update bucket for multiple files
