zip file downloading issue

Hi there, 

Welcome to the Box Community!

If you are encountering problems downloading files from your Box account, we recommend you try:

• Bulk download is dependent on the max file size upload limit for the Account type in total. See: Understand the Max File Size You Can Upload to Box.
• Files will download into the default location determined by your browser (ex. Downloads folder)
• Downloaded files from Firefox will download in Read Only mode if the download option "Open In" is selected. If you would like to edit the downloaded file, please choose the Save As option when downloading the file.
• If the option to download a file within a collaborative folder is not available to you in Box, then you may not have the proper Access Level for that collaborative folder to download the file. Please check your access level on the collaborative folder. If you are a Previewer, Uploader or Previewer-Uploader on the folder, you would not be able to download files in this folder.
• Files and Folders that are Watermarked may not be able to be downloaded normally by some collaborators. Please refer to Watermarking Files for expected behavior for each collaboration permission level on Watermarked content.
• When you download a folder from Box, the folder will download to your computer as a zipped file. You will have to unzip the folder once it has successfully downloaded to your computer. Please note that empty subfolders will be ignored and not included in the zip file.
• Box measures bandwidth usage based on downloads from open access shared links. All downloads from any public shared link count towards the bandwidth limit. Depending on the size of the files being shared and the frequency of downloads, you can reach this limit quite quickly based on the file format (GIF, FLV, MP3, and so forth). Click here for more info.

Thanks!
