Consistent with my advanced years...I am still using Micrografx Designer for various projects and have just tried to access a number of older files and get an error message saying the application can't access the files owing to an I/O problem.   Other files of the same vintage or older, open just fine.  

I can only suspect the problem files are corrupted in some way.   As they are quite complex, I am loathe to shrug my shoulders and start re-creating them from scratch.   Does anyone know of this problem and/or a file repair program that works on M. Designer files (extension .dsf)?

Cheers,

Some files that Designer 7 refuses to open might open with the current version Corel DESIGNER 12. Have a try with the trial version that is available in the Downloads section of this community.

For saving them back to a file format that Designer 7 can open you need to export them to / save as CGM in Corel DESIGNER 12.

Best regards,
Klaus.

Thanks for the quick response Klaus.   Tried that, but unfortunately get an identical result,   Corel Designer 12 opens up the files Micrographix does but also gives an I/O error for the other files that are presenting the problem.

Any aother ideas?
