What Is This Tool?
This tool packages DOT files—a plain-text graph description format—into compressed 7Z archives. It enables efficient bundling, secure storage, and simplified transfer of graph source files by leveraging 7Z's advanced compression and encryption features.
How to Use This Tool?
-
Upload your DOT files or directories containing them
-
Choose 7Z as the output archive format
-
Optionally enable encryption for secure archiving
-
Start the conversion to package your DOT files into a 7Z archive
-
Download the resulting compressed archive for storage or sharing
Key Features
-
Convert DOT graph description files into compressed 7Z archives
-
Utilize high compression rates with LZMA/LZMA2 algorithms
-
Support for AES-256 encryption to protect sensitive DOT files
-
Create multi-volume (split) archives for easier transfer
-
Preserve directory structure and multiple files inside a single archive
Examples
-
Bundle dozens of DOT files from a documentation build into one compressed 7Z archive for easy sharing with team members.
-
Secure nightly graph-analysis DOT outputs by packaging them in AES-256 encrypted 7Z archives as backups.
-
Archive large DOT file collections produced by automated tools to save disk space and maintain folder structure.
Common Use Cases
-
Reducing transfer size for DOT source files generated in build or analysis pipelines
-
Creating encrypted backups of project documentation repositories containing DOT diagrams
-
Archiving large datasets of graph descriptions to simplify long-term storage
-
Producing multi-volume archives for distributing DOT files across systems with size limitations
Tips & Best Practices
-
Use encryption when archiving sensitive DOT files to ensure data protection
-
Preserve the original directory layout within the 7Z archive for easy extraction
-
Be aware that extracting individual files from solid compressed archives might be slower
-
Use compatible third-party tools if your system lacks native 7Z support
-
After extraction, use layout/render engines like Graphviz to generate visual outputs from DOT files
Limitations
-
Archives contain DOT source files only; rendering images requires separate layout tools like Graphviz
-
Solid compression can slow extraction or modification of single DOT files within the archive
-
Some systems need third-party software to open 7Z archives, and support for newer features may vary
-
Compression and decompression may require substantial CPU and memory on limited hardware
Frequently Asked Questions
-
Can I view the graph images directly from the 7Z archive?
-
No, the archive contains only DOT source files. You need a layout or rendering tool such as Graphviz to generate visual images from the DOT files after extracting them.
-
Is the 7Z format secure for storing sensitive DOT files?
-
Yes, 7Z supports strong AES-256 encryption to protect the content of your archives, making it suitable for securely storing sensitive graph descriptions and related data.
-
Will extracting a single DOT file from a 7Z archive be fast?
-
Extraction speed can be slower with 7Z's solid compression since similar files are compressed together, making individual file access more resource-intensive.
Key Terminology
-
DOT
-
A plain-text graph description language used to specify nodes, edges, and styling, parsed by layout engines like Graphviz.
-
7Z
-
An open archive format that compresses multiple files using algorithms like LZMA and supports encryption and multi-volume archives.
-
Solid Compression
-
A compression method that processes similar files together for better compression but may slow extraction or modification of individual files.
-
AES-256 Encryption
-
A strong cryptographic technique used to securely encrypt archive contents in the 7Z format.
