I posted this question at answers.microsoft.com and they did not answer me. I have posted there before with very good response but this is the first time I did not get a response. I hope it is ok to post this here
I have discovered that in the last two months I have files lurking on my HD that are corrupted. The only way I know to find the corrupted files is to open every file on my computer by file type. When I find a corrupted file I replace it from a backup. The problem is I have over 10,000 .mht files. 4000 .doc files, 1400 .pdf files, 1300 .txt files, etc.
If I can open 200 or 400 at a time I can go through all these files quite quickly and win8 pro allows all open files from one application to close instantly.
I would open a file window, put *.mht in a search and highlight 200 files and right click and open.
The problem is win8 pro only allows opening 15 files at a time.
Is there a way to open 200 or 400 files at a time and close instantly and go on the the next 2-400 in Windows 8 professional? I have a i7 haswell 15GB memory and 2GB video card, 2Tb HD, mid-tower case. That should be enough horse power to open 200 or 400 files at a time.
Thank you for the help
