| 25 | + | ## Dependencies | |
| 26 | + | ||
| 27 | + | Small amounts of 386 assembler. | |
| 28 | + | ||
| 29 | + | ## Usage | |
| 30 | + | ||
| 31 | + | 1\. For your project open "Project-\>Compiler Options-\>Other unit files" and add the path to the FPArchive units | |
| 32 | + | ||
| 33 | + | 2\. In the "uses" clause of your unit add AbBase, AbBrowse, AbZBrows, AbUnzper, AbArcTyp | |
| 34 | + | ||
| 35 | + | 3\. Create an unzip object: | |
| 36 | + | ||
| 37 | + | ``` pascal | |
| 38 | + | UnZip := TAbUnZipper.Create(nil); | |
| 39 | + | ``` | |
| 40 | + | ||
| 41 | + | 4\. Set the directory where you want to extract the files to: | |
| 42 | + | ||
| 43 | + | ``` pascal | |
| 44 | + | UnZip.BaseDirectory := '/path/to/extract'; | |
| 45 | + | ``` | |
| 46 | + | ||
| 47 | + | 5\. To restore directories structure (optional) add this line: | |
| 48 | + | ||
| 49 | + | ``` pascal | |
| 50 | + | UnZip.ExtractOptions := [eoCreateDirs, eoRestorePath]; | |
| 51 | + | ``` | |
| 52 | + | ||
| 53 | + | 6\. Try to extract all CSV files (for example) from an archive file: | |
| 54 | + | ||
| 55 | + | ``` pascal | |
| 56 | + | try | |
| 57 | + | UnZip.FileName := '/file/to/extract.zip'; | |
| 58 | + | UnZip.ExtractFiles('*.csv'); | |
| 59 | + | except | |
| 60 | + | on E: Exception do | |
| 61 | + | begin | |
| 62 | + | //some error handling | |
| 63 | + | end; | |
| 64 | + | end; | |
| 65 | + | ``` | |
| 66 | + | ||
| 67 | + | 7\. Free the created object: | |
| 68 | + | ||
| 69 | + | ``` pascal | |
| 70 | + | UnZip.Free; | |
| 71 | + | ``` | |
| 72 | + | ||
