How to hide a file in a picture (linux/windows)

Sometimes blog does not upload attachments, but can be transmitted pictures, so we can compress the attachment in the picture (of course, the picture can not be too large).

Linux

• Store the pictures 1.jpg and file.zip files separately in one folder, such as/tmp/temp

• Ctrl + Alt + t to bring up terminal

$CD/tmp/temp

• Execute the following command:
• $cat 1.jpg File.zip >> imgfile.jpg

To retrieve hidden files directly run:

$unzip Imgfile.jpg can

Windows

• Store the pictures 1.jpg and file.zip files separately in one folder, such as C:\Temp

• Win + R-cmd-CD C:\Temp

• Execute the following command:
• $copy/b imgfile.jpg + 1.jpg File.zip

To retrieve the hidden files, use 7-zip and so on to open imgfile.jpg directly.

Imgfile.jpg is what you want, note that the picture must be in front of the zip file.
