This depends on which device you used to delete the files.
If you connect the SD card to a Mac or Windows PC and delete the files from your SD card, the deleted files will be moved to Mac Trash bin or Windows Recycle bin, they will stay there until you empty the trash bin or permanently deleted from trash bin.
If you just click the Delete button on your device, for example a camera, you may be able to find the deleted files in Deleted or Trash folder. If you cannot find a trash folder, the deleted files are still stored on the SD card until new files overwrite them.
Yes, you can.
Deleted files from an SD card can be found in the trash bin if you delete them on Mac or Windows PC, or can be undeleted from the trash folder on the device that is inserted with the SD card.
Even if you permanently delete the files from an SD card, and they vanish from the trash bin or folder, you can still recover them. Because the system or device only deletes the portal of the files so that you cannot access to them any longer, the original space will be marked as available and waits for new files to replace and overwrite. If you stop writing to the SD card right after the permanent deletion, it is still possible to recover them using a data recovery program.
We all hope it never happens, but we just got the SD card files mistakenly deleted on Mac/Windows and lost them. You might have tried to find back the deleted files from Mac Trash/Windows Recycle Bin but found nothing, because they have been permanently deleted.

Many Mac users are seeking avenues to recover deleted files from SD card for free, even without software. Here we will dig out several free SD card recovery tips that are potentially working for Mac.
As mentioned in the beginning, if you delete files from SD Card using a Mac, the files will be moved to Mac’s Trash bin and you can recover files there.
If you cannot find the deleted files in Trash Bin, it may be for the reason that your Mac just created a hidden Trash folder for external storage media due to different format. You need to show the hidden trash folder and recover your files.
Speaking of recovering files with Terminal, you may be wondering if it works. Actually, with Terminal alone, you can recover deleted files from Mac Trash only, and you won’t be able to recover deleted files from an SD Card. But with the help of PhotoRec, we can achieve this.
PhotoRec is an open source data recovery program for Mac users, which uses command line to recover more than 400 types of files, ranging from photo, video, archive to document. It is not easy to use, even though you don’t have to know much about command lines, you need to input and move between the codes carefully, any errors will lead to failed recovery.
If you have a good habit of backing up files regularly, it should be pointed out that we can recover deleted files from SD Card with backup, so that you don’t have to download any extra apps and get SD card files back without software.
Cloud services are nowadays favored by a majority of people for uploading and backing up their folders and files, which can greatly save storage space of their local devices. Mostly, Mac users will prefer iCloud. If you have done this, please refer to the following steps to do free SD card data recovery on Mac.
The final option to recover files from SD card on Mac free without software is fixing SD card issues. That comes with the possibility that the SD card gets involved in corruption and makes files stored on it invisible. In that case you need to do SD card repair, rather than SD card file recovery.
If you are looking for free ways to recover deleted files from SD Card on Windows without installing any software, here are 2 options.
Still, you are recommended to check the Recycle Bin first if you deleted the SD card files on a Windows PC. If they are still in the bin, just select and restore them.
Alternatively, as a backup solution, most PC users will choose OneDrive. In case you have backed up the SD card data with OneDrive service, deleted files can be retrieved without effort.
Which SD Card brand you are using? It is much likely you will use one of these brands: SanDisk, Lexar, Transcend, Samsung, Sony. If your SD Card is produced by these manufactures, then you can search on their official websites and check if they offer data recovery software for lost file on your SD Card. For example, SanDisk recommends using its SanDisk Rescue for data retrieval. Here we will take SanDisk as an example to recover deleted photos or videos from SD Card. Surely, it supports recovering other files, like documents, mails, music, database, archives, etc.
