Understand options and parameters: Understand the various options and parameters of the `EXPAND` command. For example, the `-F:*` option is used to extract all files. The `-R` flag is used to extract a file with a new name. 4. Rights and access rights: Make sure you have the necessary permissions to access the source directory and extract files. This is especially important if you run the command in a directory that has special access rights. 5. Storage space check: Make sure there is enough disk space on the destination directory to accommodate the extracted files. 6. Virus protection: In some cases, antivirus programs may interfere with file extraction. Make sure your security software is configured to allow the `EXPAND` command. 7. Backup: Before running the `EXPAND` command on important files, it is advisable to create a backup. This way you can restore your data in the event of unexpected problems. 8.
