Vera (Verify Archive)

Compares 2 folders or 2 files for a simple Yes/No verification of an archive or file transfer operation.

Simplifies archive verification by using a concept of 'source' & 'destination' instead of folder 1 & folder 2. Items on the destination but not on the source are ignored to avoid misleading missing file errors.

Compares any type of file: text, binary, EXE, JPG, WAV, AVI, etc. between any drives: hard discs, CD/DVDs, USB memory sticks, USB hard discs, SD cards, networks, floppy discs, etc.

The Windows file cache is bypassed to ensure the true source & destination are compared each time the check is run. Other checkers such as WinDiff & FC don't do this, but it's essential for tracking intermittent file corruption problems, otherwise you're just comparing copies held in RAM.

Verifying screenshot

It was designed to verify archives as opposed to just compare folders, so it uses the 'source' list to define all the items to be checked, and ignores any items from the destination which are not in this list.

This means you can use source & destination to reflect the direction of the original copy process and avoid misleading errors due to existing destination items missing from the source. This would occur with traditional comparison programs if you append files to an existing archive and then simply compare the two folders.

You can mimic a traditional 'compare folders' operation by clicking
Verify, Swap, Verify.

The 'More details' button shows a full list of checked files.

Comparison fails are also shown for each file such as mismatched sizes, mismatched contents, missing etc. Selected entries can be copied to the clipboard or saved to a text or CSV file:-
