Corrupted SD card

Hi,

I shot several video sequences, approx 70gb in total, to an SD card that has become corrupted. Initial I could review the videos but subsequently removed the SD card from the X3 and now the files are not displayed in file explorer but there is still 70gb of data on the card.

My local computer shop has been able to extract files but they are no longer in a formate that the Insta software can read or can combine.

The file names refer to the location the segment of the card where the data was stored and have either a mov or swf extension

Neither play in any player.

Is there any way the files can be combined in a format that will allow the Insta software to recognise and play the files?

Fingers crossed

Rob
