Uploading files
When you upload a file, it is stored in the cloud. Uploaded files consist of the file data alongside metadata that is automatically generated for the file. Metadata is supplementary information relating to the file such as the name or size. The total size of a file, within your storage bucket, is the combined sum of the file’s data and metadata.
Upload a file
You can drag and drop files into Invisaid or select files from your device. Uploads are network streams which can be paused and resumed. You can drop files into the Grid or the Explorer. Dropping files into the Explorer won’t add the files to your current case, however, dropping files into the Grid will add the files to your current case as well as initiate an upload stream.
Pause an upload
When you pause an upload, any partially uploaded data is saved in your storage bucket and consumes storage space. You can resume the upload at a later time. You can always view partially uploaded files in the Explorer and deleted to free up storage space.
Resume an upload
You can resume an upload by pressing the resume button. If you exit the upload screen, you can resume the upload by selecting the file from your device again. Invisaid will automatically detect that the file has already been partially uploaded and will resume the upload from where it left off.
Uploading many files
You can drag and drop several files into Invisaid or select multiple files from your device. When you upload many files, parallel streams are created to upload the files simultaneously. To prevent exhausting your network bandwidth, Invisaid limits the number of parallel streams depending on your network speed and device specifications.
Parallel streams may use up more of your quota. Make sure to check the limits in advance of uploading several files together. Quotas are in place for performance and security purposes. You can always raise a support request to increase your quota provided you have a valid reason for doing so.
Optimization
Invisaid automatically optimizes for all supported file formats. Optimization can vary depending on the file type but typically includes lossless compression and file system metadata removal. Uploading larger files can result in lossy compression where appropriate.
| Compression | |
|---|---|
| Type | Description |
| Lossless | Lossless compression is a method of reducing file size without losing any data. By default, Invisaid uses lossless compression to ensure that the original quality of the file is preserved. |
| Lossy | Lossy compression is a method of reducing file size by removing some data. This can result in a loss of quality, but also significantly reduces file size. Invisaid uses lossy compression for larger files where appropriate. |
Processing
Once a file is uploaded, it may need to be processed. Processing can include tasks such as generating thumbnails, extracting metadata, or converting the file to different supplementary formats. The file can still be used while it is being processed, but some features may be unavailable until processing is complete. These are temporary feature restrictions you may encounter.
| Restrictions | ||
|---|---|---|
| Process | Description | Restriction(s) |
| Antivirus scanning | Files are scanned for known viruses and malware. | Files found to contain viruses or malware will be quarantined or deleted. |
| Thumbnail generation | Thumbnails of uploaded files are generated to provide a preview of the file. This is typically instantaneous. | Thumbnails won’t be available in the file explorer. |
