Dummy File Generator

Fake File Generator

Vovsoft Dummy File Generator is a lightweight, efficient utility designed for software developers, QA testers, and system administrators who need to generate sample files instantly. Whether you are performing stress testing, checking disk usage, or evaluating network transfer speeds, this fake file generator program allows you to build massive datasets or specific test cases in seconds.

Generate Valid File Formats

Unlike basic tools that create corrupt files with fake extensions, this dummy file creator program can create valid file structures. The "Convert Filetype" feature allows you to generate files with correct headers for specific formats. This ensures compatibility when testing file parsers or upload validation logic. Supported valid formats include:

• Documents: PDF, DOC, DOCX, RTF
• Spreadsheets: XLS, XLSX
• Data & Archives: JSON, ZIP

The intuitive interface gives you total control over file attributes.

• Flexible Sizing: Generate files ranging from a few bytes to large files of several gigabytes. Use the quick-select buttons (1 KB, 1 MB, 10 MB, 100 MB, 1 GB) or enter a specific byte count.
• Custom Content: Instead of just empty files, you can fill them with data. Choose between "Char" (repeating a single character) or "Lines" (repeating a text string like "Hello World!") to verify how your software handles file content.

Fast Batch Processing ⚡

The multiple file creator is built for speed. As shown in the status bar, you can generate dozens of files in milliseconds. Simply select your destination folder, define your list of filenames (e.g., Test1.txt, Test2.txt), and hit GENERATE button. You can process thousands of files in a single batch, making it the ultimate disk space filler and test data generator.
