Photoshop can't open the solution for this file

When we are using Adobe graphics processing software, such as Photoshop, Fireworks, Illustrator, etc., we may encounter the following: - The request cannot be completed because the file format mode cannot parse the file. - Unable to open file, unknown file type. - The file could not be read because the plug-in does not recognize it. - Can't complete the request because it is not a valid Photoshop document. If you encounter the above situation, first look at the extension of the file is the image format, or although it is the image format, but it is not a normal image, but artificially modified the extension. Of course, there is a special case where you can open and view the file with an image viewer or ACDSee, but it cannot be opened with Adobe software. Solution: 1. Use the Windows picture and fax viewer or drawing tool that comes with the system to save the picture as a picture format such as .jpg; 2. If the picture on the network can be downloaded again using the download tool (such as Thunder), it is still invalid. Try to modify the extension directly.
