How to Use OpenHashTab

While the basic functionalities of OpenHashTab are straightforward, several advanced features may enhance your experience:

Select multiple files or folders to hash them all at once; you can even traverse directories.
Double-click on a hash to copy it effortlessly.
Double-click the file name or algorithm to copy the line formatted for checksum files.
Access a popup menu through right-click for additional options: copy hash, copy filename, copy line, or copy the entire output.
Status counters indicate match/mismatch results or errors, displayed in an easy-to-read format.
Sorting capabilities allow you to arrange columns lexicographically, with hash columns sorting by match type.
Selecting a tab on a checksum file interprets it to hash the listed files automatically.
If a file has a corresponding checksum file (with the same name plus a recognized extension), it can check against it if enabled.
