Built with Java + Fast CLI
What it does
FileLift (v4, versionName 2.0) uploads one or many files to any API endpoint in a single multipart/form-data request — one-call style: everything (paths, field names, extra text fields, headers) goes into one Upload block, no separate queueing blocks needed.
Key features
-
Single or multiple files per request, same or different field names per file
-
Accepts both plain file paths and modern
content://URIs from gallery/file pickers — auto-detects which, and copies to a temp cache file only when the content provider doesn't already report an exact size (so progress is always real, not simulated) -
Automatic filename & MIME-type detection (via
OpenableColumns/MimeTypeMap, falling back toapplication/octet-stream) -
Real, non-simulated upload progress — byte counts come from what's actually been written to the socket
-
Cancel one upload or all uploads mid-flight (
CancelUpload/CancelAllUploads), disconnects the liveHttpURLConnectionand firesUploadCancelled -
Headers and extra form fields passed as dictionaries, not separate blocks
-
Fully background, non-blocking network I/O (
ExecutorService), safe for many concurrent uploads tracked by your own Request ID
