Until recently, I had not heard of slack space existing within files. However, I found this site, which says the following:
"In addition to this slack space at the end of all files, the interior slack spaces of the compound files created by applications such as Word® and Excel® can also hold sensitive data scavanged by the reallocation of "deleted" clusters to those files."
From what I gather, the FAT file system wouldn't initialize slack data in OLE files, but NTFS would.
The above example seems to indicate a (rare) case in which unallocated space could inadvertently end up in a file. I'm wondering if there are other situations in which this is possible. If so, I'm also wondering which file types are susceptible to this and which aren't. I had never heard of this scenario before, so I'm wondering how common it is!
