Questions tagged [corrupt]

Data structures or files may become damaged or corrupt.

The "corrupt" tag is appropriate for questions related to damaged data structures or files:

  • detecting corruption: often related to common error messages or error states
  • preventing corruption: techniques for analyzing causes and avoiding them
  • recovering from corruption: tools and techniques for extracting partial data from damaged data structures, or restoring consistency to inconsistent data

Questions will always be in the context of a particular data structure, such as:

  • file format (zip, gzip, rar, ...)
  • file system (extfs, ntfs, ...)
  • data structure (tree, heap, memory, ...)
