File with .DASH extension contains user’s private data encrypted using Dashlane. Dash file may store such data as: Logins, Access passwords, Personal information, for example, name and surname, date of birth, etc.
Files with the .MP4 extension contain audio and video streams encoded usually in the MPEG-4 format, but they are supported also by many other formats. It is a container – file, and it may also include metadata, subtitles or images, although it is rarely used for this purpose.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the DASH file after converting to MP4 may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from DASH to MP4 to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting DASH to MP4 does not meet your expectations, you can simply try to find on the Internet a different version of your file in DASH format, properly converted to a MP4 file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file DASH the desired result was not achieved, you can try to change the format of DASH file to other than MP4. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your DASH file converted by someone else, and the attempt to convert it to MP4 on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the DASH file in its original format (without conversion to MP4 file). Such a solution will be difficult to implement, but it certainly will give the best result.
