Considering that xlsx can be used as a zip bomb and drive api can convert it into a sheet, I am wondering if there are any checks to prevent a conversion in case of a zip bomb? I have tried checking the docs but did not find any relevant information there. I did not find any such info on Stack overflow either.
The answer is no, Google Drive does not protect you from zip bombs.
Today, I verified that Google Drive will upload and store a zip bomb. Google Drive scans files under 100 MB for known viruses. I am not sure how Google classifies a zip bomb for storage and if the scanner will detect the zip bomb in the future. In the short term, the zip bomb is not flagged in Google Drive.
Google Chrome and Firefox detect zip bombs and prevent their download. Microsoft Edge permitted the download of the zip bomb.
Using the Google Drive integration with Windows Explorer (Windows 10 Professional) permitted the download of a zip bomb stored in Google Drive.
Most antivirus software will quarantine zip bombs during file scans and during downloads.
Therefore, you will need to implement additional strategies to protect systems from zip bombs.

I work for a government agency so I can't directly download R packages because we are behind a firewall. I asked the help desk for permission to download download the randomForest library. They let me download the zip file. But where do I save it so I can access it through RStudio?
So after poking around in RStudio, click on Tools->Install Packages then use the browse option to point to the saved file and it will import it.
I found a picture online: https://beta.techcrunch.com/wp-content/uploads/2010/07/q6uvf.jpg
and had an idea: I wanted to play around with DRM on .wmv and .wma files
I don't want to decrypt DRM content or strip DRM out of a file (because I don't have any files with that)
I want to encrypt a file create a license server, and then decrypt that using Windows Media Player (like that picture describes but with my own files and server)
I read on Wikipedia: https://en.wikipedia.org/wiki/Windows_Media_DRM
that I need Windows Media Rights Manager SDK to package content and create licenses
I found that some documentation on how to use that here: https://blogs.msdn.microsoft.com/mediasdkstuff/2008/09/26/wmrm-sdk-10-1-2-best-practice-sample-code/
but the page is disabled and IA doesn't have any snapshot of it
So does anyone have that SDK with some sample code (the language the sample code is in does not matter but C# would be nice)
Thanks for Anwsering and Best Regards
Today having problems with the Excel file on a Windows 7 laptop. I worked with this file last night without any problems.
The file was saved on a network drive and during saving have not been received error.
When this morning I needed to open the file I got the message about error.
"excel cannot open the file because the file format or file extension is not valid" And also the file is showing up as having 0kb.
Tried an excel repair on the file and also opening up in another program like .docx or .txt. Is there any way of finding out what happened this file or fixing the issue.
File server is running windows 2012 R2 server. Shadow copies are available and I can restore the file to previous version, however the user did alot of work after that time.
I think your file is corrupted and it may be repaired using an excel repair tool; I personally have not used the Excel version of this maker but I have used the Excel Repair Kit and password tool and they work well:
However, if the user was working for a long time Excel may have saved a copy in the users computer C:\Documents And Settings\UserName\Application Data\Microsoft\Excel\filename.xlsx.
Another thing, I use Undelete Server Edition and it has worked great for the last 5 years; every time a user saves a file it makes a copy and it stores it for the time you specify.
I am writing an app for Blackberry and will need to scan the device for certain types of media, for example, pictures, MP3s etc.
Is there an easy way to scan all the files and folders on the device itself (even just the home/user/ directory), as well as the SD card?
I'm assuming the solution is some sort of recursive algorithm whereby I get a list of directories in the current path, and scan through them, but how do I get the list of all folders (as well as files) in the path?
Thanks.

And download zip file with FileExplorerDemo. Scroll the opened page down and click on "Slow download" button.
Otherwise you may check the JDE samples folder for this sample code.
I'm using OpenXml sdk 2 to create a spreadsheet. How do I prompt the user to choose a save location?
Thanks
Open XML SDK 2.0 is used in creating the underlying XML that makes up an Excel, Word, or PowerPoint file. The functionality you are seeking is part of the Excel program and is not achievable through XML.
If you are sending the file back to the user to be downloaded they can choose where to save it from there.
