+# 7Zip
+7-Zip is a file archiver with the highest compression ratio. The program supports 7z (that implements LZMA compression algorithm), [ZIP](../../../files/ZIP.md), CAB, ARJ, GZIP, BZIP2, [TAR](compression/tar.md), CPIO, RPM and DEB formats. Compression ratio in the new 7z format is 30-50% better than ratio in [ZIP](../../../files/ZIP.md) format.
+
+## Usage
+Add file/directory to the archive (or create a new one):
+```shell
+7z a archive_name file_name
+7z a archive_name file_name -p -mhe=on # Password Protect
+```
+
+Update existing files in the archive or add new ones:
+```shell
+7z u archive_name file_name
+```
+
+List the content of an archive:
+```shell
+7z l archive_name
+```
+
+Extract files:
+```shell
+7z e archive_name # without using dir names
+7z x archive_name # extract with full paths
+7z x -ofolder_name archive_name # extract into folder
+```
+
+Check integrity of the archive:
+```shell
+7z t archive_name
+```
