.DOWNLOADING file format is used by Pando software application. This software is used for sending and receiving files which are too large to be sent through conventional file sending techniques.
This software application is generally used for sending large files which are divided into number of pieces depending upon the size of the file and while all the pieces or parts are not completely downloaded the extension of the downloading file is .DOWNLOADING. When the file is completely downloaded the extension of the file is changed to its original extension. All this process is done by the software application itself.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .DOWNLOADING file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DOWNLOADING file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DOWNLOADING file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
