Feature Details

Custom Upload Parameters

The app allows you to customize how your uploads are handled on the server:

Maximum Downloads

Purpose: Limit how many times a file can be downloaded
Default: 1 download (file is removed after first download)
Options:
- Set to any positive number to limit downloads
- Set to 0 for unlimited downloads
How to use: Enter your desired number in the "Maximum Downloads" field when uploading a file

Expiry Time

Purpose: Set how long the file remains available on the server
Default: 24 hours (1 day)
Maximum: 24 hours (server-enforced limit)
How to use: Enter your desired number of hours in the "Expiry Time" field when uploading

Upload Parameter Dialog

When you initiate an upload (either a selected file or dumpstate), the app will present a dialog where you can set these parameters before the actual upload begins. If you don't modify the fields, the default values will be used.

Server-Side File Deletion

The app integrates with the server's delete endpoint to remove files from the server when you delete them from your local history.

Single Item Deletion

When you delete a single item from your upload history:

The app attempts to delete the file from the server using its upload code
Regardless of server response, the item is removed from your local history
You will receive feedback about whether the server deletion was successful

Bulk Deletion (Clear History)

When you clear all history:

The app attempts to delete each file from the server
All items are removed from your local history
You will receive feedback about whether any of the server deletions were successful

Benefits

Privacy: Ensures your uploaded files don't remain on the server indefinitely
Resource Management: Helps keep the server storage clean
Control: Gives you full control over the lifecycle of your uploaded files

API Integration

The app uses the server's delete endpoint:

DELETE /delete/<code>

This endpoint requires the same client authentication key used for uploads. The server returns:

200 OK: File successfully deleted
404 Not Found: File doesn't exist (already deleted or expired)
401 Unauthorized: Invalid client key
