[MacTUG] What to do with a .mdlp extension from Adobe

[Edward Chrzanowski]

I needed to download the Adobe Reader app from Adobe.  It downloaded fine.  I went to launch it and matlab
complained about the file.  I was perplexed.  I know I did not download a matlab file.  I looked through the
downloads and found:
AdobeReaderInstaller_11_en_ltrosxd_aaa_aih.dmg.mdlp

A .mdlp extension.  I found this interesting gem:


Adobe distributes aps using a file management routine that appends the extension “.mdlp” to the file being downloaded. This routine is somewhat similar to the routine that Apple uses with Safari, where you will see the extension “.download” associated with files as they download.

For some reason, at times Adobe’s services will not change this appended extension before the file is handed off to your browser for downloading, so when Safari saves the file it will further append “.download” and then remove only this extension when done, resulting in the downloaded file being left with .mdlp as the final extension.

You can cure this by the following action:

I directly try to open the .mdlp-file with another program, i.e., Open With -> Other, then locating DiskImageMounter under \System\Library\CoreServices, also making sure to check the box so that DiskImageMounter becomes default.  So opening the file with DiskImageMounter works.  I got the same extension when I downloaded "flash" from Adobe.  The same trick worked.
