Script to open up pptx or .xlsx files? Answered

My hard drive is no longer working. I took it to a company to recover data from this disk. But most of the files have no original names. And besides, they don't open, probably as a result of damage. Is it possible to write a script to automatically try to open a file with the extension. pptx or .xlsx? Is it possible to make it so that the whole good files has been moved for example in the folder 'C:\Success'. The files that are corrupt in folder 'C:\Failed'. I'm not sure whether it is possible to do so? Maybe there is any guide how to restore them or utilities whether paid or free?

CorelDraw 9 Error message? Answered

I'm working with CorelDraw 9. I've been working on something for two months, it is 987Kb. Just when I was finishing the project, the file became corrupt. It upens up to 40% and then I receive the message "Error Reading myfile.cdr file". I tried importing it to a new cdr, it gets 74% done and then gives me the error message. When I click on accept, I receive an error message that says that it cannot import an empty document. I can see it in the preview box, though. I need a Corel programmer that could maybe open the file code and repair the problem. Can you help me?

Batch check the integrity of AutoCAD? Answered

We need a way to batch check the integrity of a lot of AutoCAD files and need suggestions or recommendations.  These files have been recovered from a raw data image so many of them are corrupt and will not open.  The option to move any undamaged files would be extra beneficial. The only program I have been able to find is one called SmartPurger but it does not work as AutoCAD will popup with error messages on corrupted files and stall the process.  There is an option in SmartPurger to auto accept the popups but it does not seem to actually work.  Been Googling for a few hours and it looks like it somehow may be possible with LISP or Script programming but I've got zero experience with these things. Thanks!

Unexpected error of Corel Draw file? Answered

Hi, Today, when I was working with a file in Corel and wanted to close it, I got an error "out of memory". Then I tried to do the same with other Corel files and have not got any error. I think that the problem is not in memory, because with the other small files everything is fine and my computer has 8GB memory. I tried to work with this file on another computer and there is the same problem arose. I tried to remove Corel x5 and installed it again but it did not solve the problem. Can you help me? Is there any chance that the file somehow can be corrupted, even though I worked in it? Thank you very much.

Power Point only works over remote assistance? Answered

One of our employees has a problem with pptx files in PowerPoint 2010. When  she opens her pptx file it only opens  the first slide and all the top tool bars in PowerPoint are grey and can’t be accessed. The steps I have taken are as follows: Installed the office 2007 compatibility pack although only some of the PowerPoint files were pptx. I tried open with Office 2007 but without success. I thought maybe it was created in Office 2007.   I have searched the web high and low for a solution for this and can’t find one single case with the same issues. I myself have never seen this before. The user is a local admin on her laptop. I have to add that there are no errors or warnings in event viewer. Has anyone seen anything like this?

Sent items OE folder may have been damaged? Answered

I recently received a message from OE6 that my sent items folder may have been damaged. OE6 created a new "sent items 1" folder. The original sent items folder still exists on my hard drive. I tried moving the sent items 1 out of my mail directory and moving the original sent items folder in it's place. That didn't work. It created a new sent items 1 folder which was blank. I then moved the original sent items folder to another directory and tried to import, received the standard "no files or in use by another application. Then I created a new identity and tried importing. Same result Same has now occurred to my inbox folder. Is there any utility out there that can repair a corrupted folder and then be able to import into my existing folders? How about upgrading to a full edition program like Outlook and importing from OE6? Any assistance would be nice as I would like to retrieve my old email files

DIY continuous rotating servo motor for cat toy?

I'm trying to make a cat toy for my cat based somewhat loosely off of a toy called the fling-ama-string.;=related I have one and he seems to like it but since it only moves vertically I've noticed that he gets bored quite quickly. However, when I lay the fling-ama-string horizontally on my table and the string runs over the edge of the table he plays with it a lot longer. My idea was similar to something like this: Which seems to have a motor running a line from across one side of a field to the other. I obviously do not need one as heavy duty as this but I feel like if I were to rig this around the leg of a few pieces of furniture and let my cat run around chasing the lure a few times a week he'd really enjoy it. My issue is what kind of motor do I need and how difficult is this going to be to set up? Also, I'd like to spend less than $50 on all the parts for this but seeing as how the motor itself might be somewhat pricey I can understand if it goes over my initial cap. If anyone has any ideas I'd really appreciate it!
