CrcCheckCopy Changelog

What's new in CrcCheckCopy 2.7

Apr 28, 2024
  • Internal improvements
  • Added Thumbs.db to the ignore list
  • In the scan phase, when a file cannot be read, a random CRC is given so that an error will be produced during verification
  • Added error message if the "root" folder to scan or verify does not exist (mainly because of a typing mistake)

New in CrcCheckCopy 2.6.1 (May 30, 2023)

  • Fixed: when a filename or path contains the quote (") character the program still calculates the file's CRC but does not verify the CRC and reports an error instead. This can happen on MacOS.

New in CrcCheckCopy 2.6 (Apr 9, 2023)

  • New faster CRC algorithm increases speed to 20x when calculating the CRC from files on the local SSD drive
  • CRCstamps.txt will now include the file modification date. This will allow future versions to complete the verification faster by specifying an optional flag to skip files that have the same modification date.
  • Internal improvements

New in CrcCheckCopy 2.4.1 (Mar 15, 2021)

  • Fixed:
  • Bug in reading the license file of the PRO edition under Windows.

New in CrcCheckCopy 2.2 (Feb 27, 2021)

  • Added:
  • Find zero byte files.
  • Find duplicate files by their filesize and CRC32 (The filename is not examined: only the file size and its contents are checked).
  • New command-line switch /d to scan folders for duplicate files.
  • CrcCheckCopy /d path-to-scan-for-duplicates
  • The list of the zero sized files and the duplicate files is saved in a file named "CrcCheckCopy-report-duplicates.txt"
  • You can consider the zero byte files as a special kind of duplicate files: They have the same file size kai same contents.
  • Donation reminder added. Donations are good for your karma.
  • Changed:
  • During the scan mode, (with the /scan switch) at the end of the CRCstamps.txt file, there is an extra section for the zero-bytes files and duplicate files for you to be notified about them.

New in CrcCheckCopy 2.1 (Sep 29, 2020)

  • Added:
  • For the Windows edition: Digitally code-signed.

New in CrcCheckCopy 2.0 (Jul 21, 2020)

  • Fixed:
  • Under Windows XP and Windows server 2003 32bit, there was a warning about the filesizes that do not match. But the comparison was proceeding reliably, despite the warning message. Checking of the filesizes is now fixed.

New in CrcCheckCopy 1.9 (May 15, 2020)

  • When the folder to scan does not exist, the CRCstamps.txt looks as invalid.
