+#### Replace a File
+
+Replaces a File. Currently working for already uploaded S3 bucket files.
+
+##### Example call:
+
+```typescript
+import { replaceFile } from '@iqss/dataverse-client-javascript'
+
+/* ... */
+
+const fileId = 12345
+const uploadedFileDTO: UploadedFileDTO = {
+  fileName: 'the-file-name',
+  storageId: 'localstack1://mybucket:19121faf7e7-2c40322ff54e',
+  checksumType: 'md5',
+  checksumValue: 'ede3d3b685b4e137ba4cb2521329a75e',
+  mimeType: 'text/plain'
+}
+
+replaceFile.execute(fileId, uploadedFileDTO)
+
+/* ... */
+```
+
+_See [use case](../src/files/domain/useCases/ReplaceFile.ts) implementation_.
+
+The `fileId` parameter should be a number, the numeric identifier.
+
+The `uploadedFileDTO` parameter is a [UploadedFileDTO](../src/files/domain/dtos/UploadedFileDTO.ts) and includes properties related to the uploaded files. Some of these properties should be calculated from the uploaded File Blob objects and the resulting storage identifiers from the Upload File use case.
