MMW Cloud allows uploading all common file formats within your active storage quota.
Upload methods
Section titled “Upload methods”The web cabinet at https://app.mmwcloud.tech provides two ways to add files:
- Upload File button: located at the top of the Files view. Opens your operating system file picker.
- Drag and drop: drag one or more files directly from your desktop file manager into the browser window.
Small file transfers
Section titled “Small file transfers”Files smaller than 8 MiB transfer in a single direct request. The browser computes an SHA-256 checksum, receives an authorized upload link, and delivers the binary payload directly to storage.
Multipart upload for large files
Section titled “Multipart upload for large files”Objects measuring 8 MiB and larger use multipart chunking:
- File splitting: the browser splits the payload into fixed-size chunks.
- Local hash computation: an SHA-256 checksum is calculated locally on your computer or phone prior to transmission.
- Chunk delivery: fragments upload over an encrypted channel. The server confirms each received block with an ETag token.
- Assembly: once all parts are transferred, the storage backend finalizes the object and updates its state to ready.
A progress indicator displays upload completion percentages in real time.
