DOCUMENT:Q194618 01-MAY-2001 [ssafe] TITLE :INFO: Fast Get Only Works When Compare = Checksum PRODUCT :Microsoft SourceSafe PROD/VER: OPER/SYS: KEYWORDS:kbSSafe600 kbSSExplorer ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual SourceSafe for Windows, version 6.0 ------------------------------------------------------------------------------- SUMMARY ======= The Visual SourceSafe version 6.0 database format has a new Fast Get feature, but this feature only works when files are compared by Checksum. MORE INFORMATION ================ In the Visual SourceSafe Explorer, you can set "Compare files by" (go to the Tools menu, click Options, and click the Local Files tab) to Checksum, Contents, or Time. If "Compare files By" is set to Checksum, the fast Get uses a mechanism that speeds up comparing files by checksum. It stores the checksum for every file in a directory in the VssVer.scc file in that directory and compares it with the checksum information stored in the Crcs.dat file in the Visual SourceSafe data directory. If "Compare files By" is set to Contents or Time, the fast Get does not work. If you are not using the new database format, comparing by Checksum might not be the fastest method for comparing files. For more information on comparing files with the old 5.0 database format, see the following articles in the Knowledge Base: Q131773 INFO: Setting Compare to Time Increases Speed of GET Command Q131772 INFO: Setting Compare to Checksum Speeds GET Command Q123473 HOWTO: Increase Performance in SourceSafe REFERENCES ========== Visual SourceSafe Help: Local Files Options Tab; Compare Initialization Variable Additional query words: ====================================================================== Keywords : kbSSafe600 kbSSExplorer Technology : kbSSafeSearch kbAudDeveloper kbSSafe600 Issue type : kbinfo ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
