20.4.3. File Compression Many file compression utilities exist for UNIX (e.g., compress, gzip) and Windows (e.g., PKzip, WinZip). ANSYS cannot read compressed files. However, you can compress ANSYS models to save space when archiving, so long as you uncompress the models before trying to read them into ANSYS. 20.5. Reading Your Own Files into the ANSYS Program In many situations, you will need to read in your own files while using the ANSYS program. The file may be a text file of ANSYS commands or a binary file of ANSYS data. Use the /INPUT command (Utility Menu> File> Read Input from) to read in a text file containing ANSYS commands. For instance, you can read in the log file (Jobname.LOG) from a previous ANSYS session. For example, the following command causes the ANSYS program to read the file MATERIAL.INP from the current directory. /INPUT,MATERIAL,INP Table 20.3: Commands for Reading in Text Files (p. 303) lists other commands that you can use to read in text files.
