The DekkoSecure application does not have file size limits. If you are participating in a DekkoSecure trial using dummy data and/or need to test the performance of the application without uploading sensitive material, you can easily create an test file of any size. The files created by following this guide are simply blocks of “empty” data, so they cannot be read - but they will report having a size that you specify. Uploading, downloading and sharing these files in the DekkoSecure application will reflect the same experience as interactions using your real files.
Create a large file on Windows
A file of any size can be created using the fsutil command (learn more).
Steps for creating a large file:
- Open Command Prompt (see how).
- Navigate to a directory where the new large file will be stored using the cd command. For example, cd %YOUR_USERNAME%\Desktop to navigate to your desktop folder. (learn more about file system navigation in Command Prompt).
- Enter your fsutil command, for example, fsutil file createnew test_file 5000000000.
You can use this tool to convert a desired file size to bytes.
This will create a 5GB file called test_file in your desktop folder.
Create a large file on a Mac
A file of any size can be created using the mkfile command (learn more).
Steps for creating a large file:
- Open Terminal (see how).
- Navigate to a directory where the new large file will be stored using the cd command. For example, cd desktop to navigate to your desktop folder. (learn more about file system navigation in Terminal).
- Enter your mkfile command, for example, mkfile -n 5g test_file.
This will create a 5GB file called test_file in your desktop folder.
