Trash in Mac Operating system is same like Recycle bin in Windows OS, where the files that are deleted from the finder of Mac OS are temporarily stored. Generally, Trash is an invisible folder in Mac OS, which is located at the root level of the drive. The root level of the drive is called as Desktop Folder. When you keep a file in the Trash in Mac OS X, it is temporarily stored in invisible folder of your home directory called trash. Along with root user, each user has its own trash folder, where the deleted files are temporarily stored. You are not able to view or access trash folder directly from the Mac OS GUI. The default location of Trash is root / user folder name / trash. You cannot manually allocate the size of Trash; Mac OS itself automatically allocates size of the trash. If you want to know the total size of the contents of Trash then you need to open Trash, select all files and then click on get info. Trash is a folder, which may also expand its size with each new deleted folders or files. The main difference between Trash and Recycle bin is that, you can increase, decrease or even restrict the size of Recycle bin in Windows but in Mac you cannot restrict the size of Trash.
The most common cases in which files get deleted or lost are discussed below:
Even though the files bypass the Trash, they are not permanently deleted; only the allocation information of files gets deleted making the files inaccessible. Actually, they are still present on the hard drive until they are overwritten by new data.
Therefore, while deleting you need to recheck that the file you want to delete is important to you or not. If you dont want the file to bypass the Trash then you need to disable the delete command that bypass trash option. You need to take backup of essential data because, if you didnt find your deleted file in Trash then you can easily restore it back from backup file. To recover files from emptied Recycle Bin, you can make use of the Windows version of the software.
If you dont have backup then no need to worry because, Mac file recovery software helps you to recover deleted files from Mac OS until and unless the data has not been overwritten. So, do not save or copy any new files onto the drive from where you have accidentally deleted the files. HFS+, HFSX, FAT16 and FAT32 are the different types of file systems supported by this software. It can also recover files after system restore. The software can additionally recover files from Transcend memory card and memory card of other brands like SanDisk, Kingston etc.
