During a customer engagement I was writing a PowerShell script to analyze the content of a farm. Since such scripts is very performance consuming we were working on representative site collection backups on a dedicated environment.
The script will iterate through all libraries (within webs, within sites) an write item information like "file type" or "file size" to a csv-file. Given that csv-file we were able to analyze the content by using Microsoft Excel.
On that environment we were working on 675 site collections containing 8181 webs. We were dealing with approximately 60.000 documents. On that specific environment we were figuring out that -who wonders- SharePoint Collaboration Technologies were mostly used for working with Microsoft Office files. The following image will show how the document type are distributed within our content:
Please feel free to leave a comment if you want me to publish the script as well.
Due to responses you can find the script in the following:
