I assume you meant you removed the .downloading extension not the .pdf extension; your wording is ambiguous.
Ah...interesting point. I was just eliminating the ".pdf" that I could see in the name of the file. I changed the view so I could see the complete file name, including extension, took away the ".downloading" part, which left "*.pdf" and as soon as I did that, the file changed to an Acrobat icon instead of the previous icon that I'm not familiar with. My excitement was brief - the application launches but the file doesn't open, I get the same error message.
Are the files that you can't open the sort of size you expect?
YES! That seems somewhat promising!
If you look at files while they are downloading from the Internet, there are usually two parts. One has the final filename with a size of 0. The other has the filename with an additional extension (Firefox normally adds .part for example) and this is the one that is actually increasing in size. When downloading is complete, the .part file disappears and the final file is the correct size.
There are many download managers that use similar file naming. ".downloading" could be the extension used by one of those. You seem to think you don't have any of those other than your browser. I wonder if it has something to do with the application settings for your browser (eg Firefox tools/options/applications).
It could also be another application is using similar file extensions to Acrobat. Double check in Folder Options/File types to see what the default is for pdf or similar.
It says "Adobe Acrobat" for "Content Type" and "Use Adobe Acrobat (In Firefox)" for "Action". There's a drop-down that gives me an option to use Acrobat 9.5 or Other and then browse. Or I can set it to ask me each time. I was tempted to change it to use 9.5 but thought it would be a good idea to wait for your opinion on that :-)
If there is an Advanced tab for the entry, click it and see what program is listed to open the file type (click Open then Edit, read the entry then Cancel your way out). No Advanced tab.
I have not used CrashPlan. If you can stop further backups, try to retrieve the originals. As I have mentioned a few times in the forum, any quick backup system is not a good idea. You can't usually revert to earlier versions if you've screwed up. Edit: since the files now have new names (extensions), the old files on your backup will not be overwritten. I actually went with CrashPlan after reading some positives about it on this site. As far as back ups go, I like it a lot better than others I've used (I especially like that I can restore just one folder out of hundreds) and their support team is responsive (at least on the one stupid question I had to ask. You're right about the extensions keeping the original files from being overwritten. That is making me feel a little better.
So....I'm at that place where I'm afraid to try anything for fear I'll make things worse. Having said that, it is bothering me that I am not 100% certain how I got myself into this fine mess. I thought I might try to recreate the disaster. One file I recognized as a recipe I downloaded from good old Martha Stewart. I picked it since it is one of the few files I could live without and one that I thought I may have downloaded (my work files and household finance files ....I guess I did download a lot of those with Pando when I moved them from one laptop to this one). Anyways, I went to Martha, found the recipe --- she doesn't download, per se. She has a print button. So I printed and selected Microsoft XPS Document Writer, giving it a file name with a 2 added. Once it was on my hard-drive, the brain cells kicked in. I know what I did. I right clicked an XPS file, selected Open With and because XPS is a completely different file type, I went browsing for Adobe. Several levels down, I found the application and clicked on it. There is where the damage was done. The root of my stupidity is that I always (mistakenly) assumed that XPS was just another name for pdf.
Does this additional information help? Any other ideas?
Here's a P.S. I just looked at some of my important files. Interestingly, for some that I looked at there is both a .pdf file and a .downloading file. The .pdf file opens just fine. These are files that I know came over to this machine via Pando. I'm trying to look at the bright side with this --- if I have a ton of corrupted stuff, at least it is limited to things that I have printed from the internet in the last three months. It still is a ton of files, but probably a thousand or so rather than 27,000. Of course, for all the files that have both an uncorrupted .pdf and an accompanying .downloading file, my hard drive is being gobbled.
Oh DUH! Pando is a downloader. So is Dropbox, right?
