CRC32 Calculator Command Line Publisher's description
from Andrew Koupparis
Calculate the 32-bit Cyclic Redundency Check (CRC) of a given file
The CRC32 Calculator Command Line application will calculate the 32-bit Cyclic Redundency Check (CRC) of a given file.
CRC filename [/F /H /S /D /Bxxxx /R]
Wildcards are allowed (ex. *.*)
/F to display full filename
/H to include hidden files
/S to include system files
/D to scan subdirectories
/Bxxxx to set the buffer size in Kbytes - Default = 1024
/R to supress progress report
/? displays this screen
Parameters may stack (you can type /fhsdrb1024 and it will be accepted)
You may wish to increase buffer size if dealing with *large* files, do not however use a larger buffer than the physical memory. The minimum value is 1 KB = 1024 bytes, the default is 1 MB. Depending on the system, the available RAM and the file size different values may have quicker results. If the file is larger than the buffer you will also see a progress indicator.
The result will be something like: "filename - CRC32: $xxxxxxxx" or, if you use wildcards (as *.*) a list of the files and their CRCs.
Note that the procedure may take time for large (or many) files, so using a command like: crc32 *.* /d in the root directory may *take a while*.
The great thing about command-line is that using the " >filename" parameter you pass the results to the file. So a "crc32 *.* /fhsdr >result.txt" will create a quite flexible result list.
System Requirements:No special requirements.
