In Microsoft Exchange Server, the Esefile is an inbuilt utility that is used to copy files and test checksum. Different switches are used to perform specific task using this tool. This utility can be used on Microsoft Exchange Server 2000 and 5.5. In some situations, this utility may cause checksum errors and database corruption if you use incorrect switches. In such cases, all of your critical data becomes inaccessible and serious data loss situations occur. At this point, to retrieve your valuable data, you are required to opt for Exchange Server Recovery.
The command line format of Esefile tool is as follows:
Esefile [/c source destination] [/x file] [/s file] [/d file page number]
/c Copy source files to destination
/x Test Edb.dll format checksum
/s Test Ese.dll format checksum
/d Dumps a page from file
When you test checksum using this tool, it verifies page-level integrity of the database. It tests at speed of about 1 GB per minute.
