Upload files to your cloud account
Uploading a file to CloudVault stores that file in the account associated with the authenticated user. Instead of uploading a separate copy every time the same file needs to be shared, CloudVault keeps a single stored object and references that object through its file metadata.
This architecture makes it possible for the same uploaded file to appear in both supported Android clients and the web interface. File size, MIME type, checksum and ownership data can be maintained by the production backend.
Manage files from the web
The CloudVault web interface provides access to your cloud library from a normal browser. Uploaded files can be listed with useful information such as their file name, type, size, storage usage and account ownership.
File-management tools can also be used to organize and rename content. Renaming changes the display metadata while allowing the original privately stored binary object to remain managed by the backend.
Secure public share links
When a CloudVault user shares a file, the system can create a unique token-based URL. The public recipient receives the share URL rather than the private server storage path.
The token is resolved by CloudVault on the server. If the share remains valid, the backend can display the appropriate file information and provide controlled access to the same stored file.
This approach avoids exposing the real private object directory to the browser and gives CloudVault control over whether a particular public share should remain usable.
Password protection
A file owner may choose to protect a share using a password. When protection is enabled, the recipient must enter the correct password before CloudVault grants access to the protected destination.
For sensitive files, send the password separately from the public URL. This reduces the risk of both pieces of information being exposed together.
CloudVault across devices
A cloud-storage service becomes more useful when account information is synchronized instead of isolated on one device. CloudVault uses its production backend as the authoritative source for files and account storage data.
This means a supported Android app or web session can request the user file list from the server and display the current state associated with that account.
A simple file workflow
File previews
Certain supported files can be previewed directly inside the CloudVault share page. Images can be rendered in the browser, while supported audio and video formats can use browser media controls.
Previewing a file does not need to create another permanent copy of that file. The preview and download routes can access the same privately stored object after the server validates the request.
Storage plans and quotas
Different users may require different amounts of storage. CloudVault can associate an account with a particular storage quota and track how much space the account currently uses.
Before beginning a large upload, checking the remaining storage allowance can help prevent unnecessary failed transfers. Large files also require a stable connection and naturally take longer to send than smaller files.
Keeping your files organized
As a cloud library grows, descriptive file names and folders make content much easier to find. Instead of keeping automatically generated file names forever, users can rename files to something meaningful and organize related material together.
A well-organized cloud account also reduces the chance of sharing the wrong file. Always verify the selected file name and preview before sending a public link.
Security best practices
Always protect your CloudVault account with a strong password that is not reused across unrelated services. Do not send your account password to someone simply because you want to share a file.
Public sharing exists specifically so recipients can access an authorized file without signing into the owner account. Use password-protected share links when an additional layer of access control is appropriate.
Managing old links
A share link does not necessarily need to remain active forever. When access is no longer needed, the file owner can revoke the share so that the corresponding token no longer provides normal access.
Regularly reviewing old public links is a useful habit, especially when the files contain private or temporary material.
Why checksums matter
A cryptographic checksum such as SHA-256 provides a compact way to identify the contents of a file. Cloud storage systems can use checksums during upload and storage workflows to help verify file integrity.
When the bytes remain unchanged, the same file produces the same SHA-256 checksum. This is useful when confirming that a downloaded object matches the object that was originally stored.
