Archive Your FTS File in 7Z Format
Convert and archive FTS astronomical files into 7Z format to save storage space, organize multiple files, and enable secure transfers with optional encryption and multi-volume support.
Quick Access To 3 FTS File Conversion Pairs
What Is This Tool?
This tool converts FTS (FITS) files, a specialized astronomical image format, into the 7Z archive format. It applies efficient compression, bundles multiple files, and supports secure encryption and multi-volume archives for easier storage and transfer.
How to Use This Tool?
- Upload your FTS files or folder containing multiple FTS files to the tool
- Select 7Z as the output archive format
- Choose compression level and optional encryption if needed
- Start the conversion and wait for the compressed 7Z archive to be generated
- Download the resulting 7Z file for storage, sharing, or backup
Key Features
- Converts FTS files (astronomical FITS images and data) into compressed 7Z archives
- Supports high compression with LZMA/LZMA2 and solid compression for improved space savings
- Enables AES-256 encryption for secure backups and transfers
- Creates multi-volume (split) archives for size-limited transfers
- Preserves original directory structure within the archive
Examples
- Scientists bundling a night’s FTS images and calibration files into one 7Z archive to speed up uploads to remote centers
- Creating encrypted 7Z archives of FITS survey datasets for secure off-site storage
- Packing large FTS datasets into split multi-volume 7Z archives to transfer across media with size restrictions
- Archiving processed pipeline outputs preserving both images and associated data tables in one compressed file
Common Use Cases
- Saving disk space by compressing large collections of raw or calibrated FITS/FTS files
- Simplifying data distribution by grouping many FITS files into a single 7Z container
- Securing FITS datasets with AES-256 encrypted 7Z backups for long-term storage
- Handling very large datasets by creating multi-volume archives for easier transport
Tips & Best Practices
- Use FITS-aware software to open and analyze files extracted from 7Z archives
- Consider enabling encryption for sensitive astronomical data backups
- Create multi-volume archives when file sizes exceed transfer or storage limits
- Be aware that solid compression can slow extraction of individual files
- Ensure you have a compatible 7Z extractor that supports features like LZMA2 and header encryption
Limitations
- Extracted FTS files still require specialized FITS software to interpret HDUs and metadata correctly
- Solid compression may increase overhead for accessing or modifying isolated files
- Not all systems support 7Z format natively; third-party tools are often required
- Some extractors lack support for newer 7Z features such as LZMA2 or encrypted headers
- Compression and decompression can be resource-intensive on limited hardware
Frequently Asked Questions
- Can I open 7Z archives on any operating system?
- While 7Z is open and cross-platform, not all operating systems support it natively. Usually, you need third-party software like 7-Zip to open 7Z archives.
- Does archiving FTS files in 7Z format change the original data?
- No. The 7Z archive compresses the files without modifying the FITS data or headers, preserving the original scientific metadata intact.
- Is encryption available when creating 7Z archives from FTS files?
- Yes. You can enable AES-256 encryption during compression to secure your FITS datasets for storage or transfer.
Key Terminology
- FTS (FITS)
- An astronomical file format for storing images and tables with metadata, designed for high-precision scientific data.
- 7Z
- A compressed archive format that supports high-ratio compression, encryption, and multi-volume archives.
- AES-256 Encryption
- A strong encryption standard that secures archive contents against unauthorized access.
- Solid Compression
- A compression method that processes multiple files together to improve compression ratio but can slow individual extraction.
