Here is an example of how you
can create file lists; the basis for the file
server functionality .
Powercopy provides the user the opportunity to create a CRC32 generated file list before installing a new software program. The purpose of this feature is obvious to anyone who has, after installing new software, encountered general system problems. Creating a file list prior to software installation is useful for troubleshooting errors resulting from the installation. This feature can prevent a virtual disaster as it allows a complete analysis of which system files have been replaced, added or changed by the Installation program. The Powercopy generated file list contains all needed file attributes (file name, folder name, CRC32-Checksum, file size, etc). After the installation compare the previously created file list with the file last created during the software installation (see below). This function is invaluable to a service technician as sometimes a new installation may create such problems as to require a reinstallation of the O/S.
The file list creation is performed
under the Windows DOS Shell. Before generating a file list read the Caution
Step 1. Enter the DOS Shell: Select 'Start' then 'Run' then type "command" in the 'Run' text box and press 'Enter'.
Step 2. Select the folder (directory or subdirectory) you want checked along with any or all subfolders.
Step 3. Type pc /mlb * /f- *.doc *.txt *.x* *.ht* *.gif *.jpg creates the file list (this is only one example).
Step 4. Return to Windows (type 'exit' then press 'Enter') and perform the software installation.
Step 5. After you have installed the software you can compare the new file list with the original one:
Next, exit to the DOS Shell (see above) and select the path (directory or subdirectory) where the original file list was created and type pc /check [@filelst.pc@].
Caution: During the creation of file lists, access violations may occur...for example:
"Sharing violation reading drive
"Abort, Retry, Fail"
If such messages occur type the
'f' key to continue the file list generation. The file list creation continues,
but for this file or any other generating the above message, no CRC will
be available. These denied system files are normally not essential to new
software installations and therefore are only listed by date, size and
time. The file name for the check list is: @filelst.pc@. This list contains
the file attributes and checksum and is located in the directory where
the file list was created. To view the results, double-click the
file icon (after returning to Windows). A text-editor will display the
