SDHC card renamed?

I inserted a SDHC card into a USB reader and when the file options came up, I chose to view the pics…which was fine and I looked at several.  I wanted to edit a few of them so I closed the viewer program and went to COMPUTER > EOS_DIGITAL (E; DRIVE) >  as always, 2 file options opened (DCIM and MISC) > I doubled clicked DCIM and that in turn opened the same 2 customary files (100CANON and EOSMISC) > I then double clicked the 100CANON - instead of pictures becoming available the disk renamed and I cannot access the pictures.  The snip of what the file name now looks like is attached…it seems that the datat is still present, I cannot access it because of the error "The specified path does not exist.  Check the path and try again"  I have also attached a snip of what this error message looks like.  I would appreciate the help.📎SDHC card label.PNG📎Error message.JPG

I suspect that there are characters now in the name that the computer doesn't recognize… thus the "path does not exist" message.

You might try renaming the file and then trying to open it… but once the storage device is corrupted, it's anybody's guess as to what will happen.

It has been my experience that this corruption is most likely to occur if the device is removed from a card reader without being unmounted.  You always want to get the "it is safe to remove the device" prior to removing it.

So, when I insert the USB card viewer, how do I rename it?

right click and select rename.
